George III was the third British monarch of the House of Hanover, but unlike his two predecessors, he was born in Great Britain, spoke English as his first language, and never visited Hanover. His reign was marked by a series of military conflicts involving his kingdoms, much of the rest of Europe, and places farther afield. Early in his reign, Great Britain defeated France in the Seven Years' War, becoming the dominant European power in North America and India. However, many of Britain's American colonies were soon lost in the American War of Independence. Further wars against revolutionary and Napoleonic France from 1793 concluded in the defeat of Napoleon at the Battle of Waterloo in 1815.

Later in life, George III had recurrent mental illness. After a final relapse in 1810, a regency was established, and George III's eldest son, George, Prince of Wales, ruled as Prince Regent.

Frederick North, 2nd Earl of Guilford, (13 April 1732 – 5 August 1792), better known by his courtesy title Lord North, which he used from 1752 to 1790, was Prime Minister of Great Britain from 1770 to 1782. He led Great Britain through most of the American War of Independence. He also held a number of other cabinet posts, including Home Secretary and Chancellor of the Exchequer.

North's reputation among historians has swung back and forth. It reached its lowest point in the late nineteenth century when he was depicted as a creature of the king and an incompetent who lost the American colonies. In the early twentieth century a revisionism emphasised his strengths in administering the Treasury, handling the House of Commons, and in defending the Church of England.

The American Revolutionary War, also known as the American War of Independence, was an 18th-century war between Great Britain and its Thirteen Colonies (allied with France) which declared independence as the United States of America.

After 1765, growing philosophical and political differences strained the relationship between Great Britain and its colonies. Patriot protests against taxation without representation followed the Stamp Act and escalated into boycotts, which culminated in 1773 with the Sons of Liberty destroying a shipment of tea in Boston Harbor. Britain responded by closing Boston Harbor and passing a series of punitive measures against Massachusetts Bay Colony. Massachusetts colonists responded with the Suffolk Resolves, and they established a shadow government which wrested control of the countryside from the Crown. Twelve colonies formed a Continental Congress to coordinate their resistance, establishing committees and conventions that effectively seized power

Sir Humphry Davy, was a Cornish chemist and inventor, who is best remembered today for isolating, using electricity, a series of elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as discovering the elemental nature of chlorine and iodine. He also studied the forces involved in these separations, inventing the new field of electrochemistry. In 1799 Davy experimented with nitrous oxide and became astonished that it made him laugh, so he nicknamed it "laughing gas", and wrote about its potential anaesthetic properties in relieving pain during surgery.

He also invented the Davy lamp which allowed miners to work safely with flame based lamps in the presence of flammable gases. He joked that his assistant Michael Faraday was his greatest discovery.

The Iron Bridge is a bridge that crosses the River Severn in Shropshire, England. Opened in 1781, it was the first major bridge in the world to be made of cast iron, and was greatly celebrated after construction owing to its use of the new material.

In 1934 it was designated a Scheduled Ancient Monument and closed to vehicular traffic. Tolls for pedestrians were collected until 1950, when ownership of the bridge was transferred to Shropshire County Council. It now belongs to Telford and Wrekin Borough Council. The bridge, the adjacent settlement of Ironbridge and the Ironbridge Gorge form the UNESCO Ironbridge Gorge World Heritage Site.

Charles Watson-Wentworth, 2nd Marquess of Rockingham, was a British Whig statesman, most notable for his two terms as Prime Minister of Great Britain. He became the patron of many Whigs, known as the Rockingham Whigs, and served as a leading Whig grandee. He served in only two high offices during his lifetime (Prime Minister and Leader of the House of Lords), but was nonetheless very influential during his one and a half years of service.

Rockingham's administration was dominated by the American issue. Rockingham wished for repeal of the Stamp Act 1765 and won a Commons vote on the repeal resolution by 275 to 167 in 1766. However Rockingham also passed the Declaratory Act, which asserted that the British Parliament had the right to legislate for the American colonies in all cases whatsoever.

William Petty, 1st Marquess of Lansdowne, (2 May 1737 – 7 May 1805), known as The Earl of Shelburne between 1761 and 1784, by which title he is generally known to history, was an Irish-born British Whig statesman who was the first Home Secretary in 1782 and then Prime Minister in 1782–83 during the final months of the American War of Independence. He succeeded in securing peace with America and this feat remains his most notable legacy.

In March 1782 following the downfall of the North Government Shelburne agreed to take office under Lord Rockingham on condition that the King would recognise the United States.

William Henry Cavendish Cavendish-Bentinck, 3rd Duke of Portland, (14 April 1738 – 30 October 1809) was a British Whig and Tory politician during the late Georgian era. He served twice as British prime minister, of Great Britain (1783) and then of the United Kingdom (1807–09). The twenty-four years between his two terms as Prime Minister is the longest gap between terms of office of any British prime minister.

During his tenure the Treaty of Paris was signed formally ending the American Revolutionary War. The government was brought down after losing a vote in the House of Lords on its proposed reform of the East India Company after George III had let it be known that any peer voting for this measure would be considered his personal enemy.

William Pitt the Younger (28 May 1759 – 23 January 1806) was a prominent British Tory statesman of the late 18th and early 19th centuries. He became the youngest British prime minister in 1783 at the age of 24. He left office in 1801, but was Prime Minister again from 1804 until his death in 1806. He is known as "the Younger" to distinguish him from his father, William Pitt, 1st Earl of Chatham, called William Pitt the Elder or simply "Chatham", who had previously served as Prime Minister.

The younger Pitt's prime ministerial tenure, which came during the reign of George III, was dominated by major events in Europe, including the French Revolution and the Napoleonic Wars. Pitt, although often referred to as a Tory, or "new Tory", called himself an "independent Whig" and was generally opposed to the development of a strict partisan political system. He led Britain in the great wars against France and Napoleon. Pitt was an outstanding administrator who worked for efficiency and reform, bringing in a new generation of outstanding administrators.

Since 1718, Britain had transported convicts to its North American colonies, until this was ended by the American War of Independence. On 13 May 1787, penal transportation resumed with a fleet of convict ships from Portsmouth for Botany Bay. This marked the beginning of transportation to Australia. Between 1787 and 1868, when transportation was abolished, over 150,000 felons were exiled to New South Wales, Van Diemen's Land and Western Australia

Michael Faraday was a British scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis.

Faraday received little formal education but he was one of the most influential scientists in history. It was his research on the magnetic field around a conductor carrying a direct current that established the basis of the electromagnetic field. He also discovered the principles of electromagnetic induction and diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices was the basis of electric motor technology, and it was due to his efforts that electricity became practical for use in technology.

As a chemist, Faraday discovered benzene, investigated the clathrate hydrate of chlorine, invented an early form of the Bunsen burner and the system of oxidation numbers, and popularised terminology such as "anode", "cathode", "electrode" and "ion." The SI unit of capacitance is named in his honour: the farad.

Charles Babbage was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer.

Considered by some to be a "father of the computer", Babbage is credited with inventing the first mechanical computer that eventually led to more complex electronic designs, though all the essential ideas of modern computers are to be found in Babbage's analytical engine. His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century.

Parts of Babbage's incomplete mechanisms are on display in the Science Museum in London. In 1991, a functioning difference engine was constructed from Babbage's original plans. Built to tolerances achievable in the 19th century, the success of the finished engine indicated that Babbage's machine would have worked.

Edward Jenner was an English physician and scientist who was the pioneer of smallpox vaccine, the world's first vaccine. The terms "vaccine" and "vaccination" are derived from Variolae vaccinae (smallpox of the cow), the term devised by Jenner to denote cowpox. He used it in 1796 in his "Inquiry into the Variolae vaccinae known as the Cow Pox," in which he described the protective effect of cowpox against smallpox.

Jenner is often called "the father of immunology", and his work is said to have "saved more lives than the work of any other human". In Jenner’s time, smallpox killed around 10 percent of the population, with the number as high as 20 percent in towns and cities where infection spread more easily. In 1821 he was appointed physician extraordinary to King George IV

The Franco-American War more properly known as The Quasi-War was an undeclared war fought almost entirely at sea between the United States and France from 1798 to 1800 which broke-out during the beginning of John Adams' presidency.

After the French crown was overturned during the French Revolutionary Wars, the United States refused to continue repaying its large debt to France, which had supported it during its own revolution. It claimed that the debt had been owed to a previous regime. France was also outraged over the Jay Treaty and that the United States was actively trading with Britain, with whom they were at war. In response France authorized privateers to conduct attacks on American shipping, seizing numerous merchant ships, and ultimately leading the U.S. to retaliate.

The census was introduced to help the government understand the country's demographic layout and better utilise the population in wartime. A census of England and Wales, and a separate one of Scotland, has been taken ever since on a ten-yearly basis, with the exception of 1941. In 1801, information was collected on a parish basis. It was not until 1841 that more detailed information was requested.

Henry Addington, 1st Viscount Sidmouth, (30 May 1757 – 15 February 1844) was a British statesman who served as Prime Minister from 1801 to 1804. He is best known for obtaining the Treaty of Amiens in 1802, an unfavourable peace with Napoleonic France which marked the end of the Second Coalition during the French Revolutionary Wars. When that treaty broke down he resumed the war but he was without allies and conducted a relatively weak defensive war, ahead of what would become the War of the Third Coalition. He was forced from office in favour of William Pitt the Younger, who had preceded Addington as Prime Minister.

The Napoleonic Wars were a series of major conflicts pitting the French Empire and its allies, led by Napoleon I, against a fluctuating array of European powers formed into various coalitions, financed and usually led by the United Kingdom. The wars stemmed from the unresolved disputes associated with the French Revolution and its resultant conflict

William Pitt the Younger (28 May 1759 – 23 January 1806) was a prominent British Tory statesman of the late 18th and early 19th centuries. He became the youngest British prime minister in 1783 at the age of 24. He left office in 1801, but was Prime Minister again from 1804 until his death in 1806. He is known as "the Younger" to distinguish him from his father, William Pitt, 1st Earl of Chatham, called William Pitt the Elder or simply "Chatham", who had previously served as Prime Minister.

The younger Pitt's prime ministerial tenure, which came during the reign of George III, was dominated by major events in Europe, including the French Revolution and the Napoleonic Wars. Pitt, although often referred to as a Tory, or "new Tory", called himself an "independent Whig" and was generally opposed to the development of a strict partisan political system. He led Britain in the great wars against France and Napoleon. Pitt was an outstanding administrator who worked for efficiency and reform, bringing in a new generation of outstanding administrators.

The Battle of Trafalgar took place between the British Royal Navy amd the fleets of the French & Spanish during the Napoleonic Wars (1796–1815). 27 British ships led by Admiral Lord Nelson on HMS Victory defeated 33 French & Spanish ships under French Admiral Villeneuve. The battle took place in the Atlantic Ocean off the SW coast of Spain, just west of Cape Trafalgar. The Franco-Spanish fleet lost 22 ships, the British lost none

William Wyndham Grenville, 1st Baron Grenville, (25 October 1759 – 12 January 1834) was a British Pittite Tory and politician who served as Prime Minister of the United Kingdom from 1806 to 1807, though he was a supporter of the British Whig Party for the duration of the Napoleonic Wars.

Following Pitt's death in 1806, Grenville became the head of the "Ministry of All the Talents", a coalition between Grenville's supporters, the Foxite Whigs, and the supporters of former Prime Minister Lord Sidmouth, with Grenville as First Lord of the Treasury and Fox as Foreign Secretary as joint leaders. The Ministry ultimately accomplished little, failing either to make peace with France or to accomplish Catholic emancipation (the later attempt resulting in the ministry's dismissal in March, 1807). It did have one significant achievement, however, in the abolition of the slave trade in 1807.

Isambard Kingdom Brunel (9 April 1806 – 15 September 1859), was an English mechanical and civil engineer who is considered "one of the most ingenious and prolific figures in engineering history", "one of the 19th-century engineering giants", and "one of the greatest figures of the Industrial Revolution, who changed the face of the English landscape with his groundbreaking designs and ingenious constructions". He also had the most outstanding name!

Brunel built dockyards, the Great Western Railway, a series of steamships including the first propeller-driven transatlantic steamship, and numerous important bridges and tunnels. His designs revolutionised public transport and modern engineering.

William Henry Cavendish Cavendish-Bentinck, 3rd Duke of Portland, (14 April 1738 – 30 October 1809) was a British Whig and Tory politician during the late Georgian era. He served twice as British prime minister, of Great Britain (1783) and then of the United Kingdom (1807–09). The twenty-four years between his two terms as Prime Minister is the longest gap between terms of office of any British prime minister.

During his tenure the Treaty of Paris was signed formally ending the American Revolutionary War. The government was brought down after losing a vote in the House of Lords on its proposed reform of the East India Company after George III had let it be known that any peer voting for this measure would be considered his personal enemy.

Spencer Perceval (1 November 1762 – 11 May 1812) was a British statesman who served as Prime Minister of the United Kingdom from October 1809 until his assassination in May 1812.[1] Perceval is the only British prime minister to have been murdered. He was also the only Solicitor General or Attorney General to become Prime Minister.

Perceval faced a number of crises during his term in office, including an inquiry into the Walcheren expedition, the madness of King George III, economic depression and Luddite riots. He overcame these crises, successfully pursued the Peninsular War in the face of opposition defeatism, and won the support of the Prince Regent. His position was looking stronger by early 1812, when, in the lobby of the House of Commons, he was assassinated by a merchant with a grievance against his government.

Charles Dickens is famous for his novels that touch upon the sensitive issues of poverty, child labour, and slavery. During a time when poverty was rife he had the courage to voice his opposition. Most of the characters in his novels are based on people he was acquainted with. This includes his own parents, who were the models for characters Mr & Mrs Micawber in ‘David Copperfield’

Robert Banks Jenkinson, 2nd Earl of Liverpool, (7 June 1770 – 4 December 1828) was a British statesman and Prime Minister (1812–27). As Prime Minister, Liverpool called for repressive measures at domestic level to maintain order after the Peterloo Massacre of 1819. He dealt smoothly with the Prince Regent when King George III was incapacitated. He also steered the country through the period of radicalism and unrest that followed the Napoleonic Wars. He favoured commercial and manufacturing interests as well as the landed interest. He sought a compromise of the heated issue of Catholic emancipation. The revival of the economy strengthened his political position. By the 1820s he was the leader of a reform faction of "Liberal Tories" who lowered the tariff, abolished the death penalty for many offences, and reformed the criminal law.

The War of 1812 was a conflict fought between the United States and the United Kingdom, and their respective allies from June 1812 to February 1815. Historians in Britain often see it as a minor theater of the Napoleonic Wars; in the United States and Canada, it is seen as a war in its own right.

Peace negotiations began in August 1814, and the Treaty of Ghent was signed on December 24. News of the peace did not reach America for some time. Unaware of the treaty, British forces invaded Louisiana and were defeated at the Battle of New Orleans in January 1815. These late victories were viewed by Americans as having restored national honour, leading to the collapse of anti-war sentiment and the beginning of the Era of Good Feelings, a period of national unity. News of the treaty arrived shortly thereafter, halting military operations. The treaty was unanimously ratified by the US Senate on February 17, 1815, ending the war with no boundary changes.

Sir Henry Bessemer was an English inventor, whose steel-making process would become the most important technique for making steel in the nineteenth century for almost one century from 1856 to 1950. He also played a significant role in establishing the town of Sheffield as a major industrial centre.

Bessemer had been trying to reduce the cost of steel-making for military ordnance, and developed his system for blowing air through molten pig iron to remove the impurities. This made steel easier, quicker and cheaper to manufacture, and revolutionized structural engineering. Bessemer also made over 100 other inventions in the fields of iron, steel and glass and profited financially from their success.

The Corn Laws were tariffs and trade restrictions on imported food and grain ("corn") enforced in Great Britain between 1815 and 1846. They were designed to keep grain prices high to favour domestic producers and imposed steep import duties, making it too expensive to import grain from abroad, even when food supplies were short.

The laws became the focus of opposition from urban groups who had far less political power than rural Britain. The Irish famine of 1845–1852 forced a resolution because of the urgent need for new food supplies. Prime Minister Sir Robert Peel, a Conservative, achieved repeal with the support of the Whigs in Parliament, overcoming the opposition of most of his own party.

The Second Barbary War (1815) was fought between the United States and the North African Barbary Coast states of Tripoli, Tunis, and Ottoman Algeria. The war ended when the United States Senate ratified Commodore Stephen Decatur’s Algerian treaty on December 5, 1815. However, Dey Omar Agha of Algeria repudiated the US treaty, refused to accept the terms of peace that had been ratified by the Congress of Vienna, and threatened the lives of all Christian inhabitants of Algiers. William Shaler was the US commissioner in Algiers who had negotiated alongside Decatur, but he had to flee aboard British vessels and watch rockets and cannon shot fly over his house "like hail" during the Bombardment of Algiers (1816). He negotiated a new treaty in 1816 which was not ratified by the Senate until February 11, 1822 because of an oversight.

The Battle of Waterloo was fought near Waterloo in present-day Belgium. A French army under the command of Emperor Napoleon Bonaparte was defeated by two of the armies of the Seventh Coalition: a British-led Allied army under the command of the Duke of Wellington, and a Prussian army under the command of Gebhard Leberecht von Blücher, Prince of Wahlstatt. The battle marked the end of the Napoleonic Wars

Augusta Ada King, Countess of Lovelace (née Byron) was an English mathematician and writer, known for her work on Charles Babbage's mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and published the first algorithm intended to be carried out by such a machine. As a result, she is sometimes regarded as the first to recognise the full potential of a "computing machine" and the first computer programmer.

Lovelace was the only legitimate child of the poet Lord Byron and his wife Anne Isabella "Annabella" Milbanke, Lady Wentworth. Ada translated an article by Italian military engineer Luigi Menabrea, on the Babbage engine, supplementing it with a set of notes, which contain what many consider to be the first computer program, an algorithm designed to be carried out on the engine, if it had ever been built.

James Prescott Joule (24 December 1818 – 11 October 1889) was an English physicist, mathematician and brewer, born in Salford, Lancashire. Joule studied the nature of heat, and discovered its relationship to mechanical work. This led to the law of conservation of energy, which in turn led to the development of the first law of thermodynamics. The SI derived unit of energy, the joule, is named after him.

Joule worked with Lord Kelvin to develop an absolute thermodynamic temperature scale, which came to be called the Kelvin scale. Joule also made observations of magnetostriction, and he found the relationship between the current through a resistor and the heat dissipated, which is also called Joule's first law. His experiments about energy transformations were first published in 1843.

George IV was King of the United Kingdom of Great Britain and Ireland and King of Hanover following the death of his father, King George III, on 29 January 1820, until his own death ten years later. From 1811 until his accession, he served as Prince Regent during his father's final mental illness.

George IV led an extravagant lifestyle that contributed to the fashions of the Regency era. He was a patron of new forms of leisure, style and taste. He commissioned John Nash to build the Royal Pavilion in Brighton and remodel Buckingham Palace, and Sir Jeffry Wyattville to rebuild Windsor Castle.

His charm and culture earned him the title "the first gentleman of England", but his dissolute way of life and poor relationships with his parents and his wife earned him the contempt of the people and dimmed the prestige of the monarchy.

Florence Nightingale, (12 May 1820 – 13 August 1910) was an English social reformer and statistician, and the founder of modern nursing.

Nightingale came to prominence while serving as a manager and trainer of nurses during the Crimean War, in which she organised care for wounded soldiers. She gave nursing a favourable reputation and became an icon of Victorian culture, especially in the persona of "The Lady with the Lamp" making rounds of wounded soldiers at night. In 1860, Nightingale laid the foundation of professional nursing with the establishment of her nursing school at St Thomas' Hospital in London.

Louis Pasteur (December 27, 1822 – September 28, 1895) was a French biologist, microbiologist and chemist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. His discoveries have saved many lives. He reduced mortality from puerperal fever, and created the first vaccines for rabies and anthrax. His medical discoveries provided direct support for the germ theory of disease and its application in clinical medicine. He is best known to the general public for his invention of the technique of treating milk and wine to stop bacterial contamination, a process now called pasteurization.

William Thomson, 1st Baron Kelvin, (26 June 1824 – 17 December 1907) was a Scots-Irish mathematical physicist and engineer who was born in Belfast. At the University of Glasgow he did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics, and did much to unify the emerging discipline of physics in its modern form.

He also had a career as an electric telegraph engineer and inventor, which propelled him into the public eye and ensured his wealth, fame and honour. He had extensive maritime interests and was most noted for his work on the mariner's compass, which previously had limited reliability. Absolute temperatures are stated in units of kelvin in his honour.

The Stockton and Darlington Railway (S&DR) was a railway company that operated in north-east England from 1825 to 1863. The world's first public railway to use steam locomotives, its first line connected collieries near Shildon with Stockton-on-Tees and Darlington, and was officially opened on 27 September 1825. The movement of coal to ships rapidly became a lucrative business, and the line was soon extended to a new port and town at Middlesbrough. While coal wagons were hauled by steam locomotives from the start, passengers were carried in coaches drawn by horses until carriages hauled by steam locomotives were introduced in 1833.

Joseph Lister, 1st Baron Lister, (5 April 1827 – 10 February 1912), was a British surgeon and a pioneer of antiseptic surgery. He promoted the idea of sterile surgery while working at the Glasgow Royal Infirmary. Lister successfully introduced carbolic acid (now known as phenol) to sterilise surgical instruments and to clean wounds.

Applying Louis Pasteur's advances in microbiology, Lister championed the use of carbolic acid as an antiseptic, so that it became the first widely used antiseptic in surgery. He first suspected it would prove an adequate disinfectant because it was used to ease the stench from fields irrigated with sewage waste.

Lister's work led to a reduction in post-operative infections and made surgery safer for patients, distinguishing him as the "father of modern surgery".

George Canning (11 April 1770 – 8 August 1827) was a British Tory statesman who served as Prime Minister of the United Kingdom from April to August 1827. He occupied various senior cabinet positions under numerous prime ministers, before eventually serving himself as Prime Minister for the final four months of his life.

He died after a mere 119 days in office which, to this day, remains the shortest tenure of any British Prime Minister.

Frederick John Robinson, 1st Earl of Ripon, (1 November 1782 – 28 January 1859), known as The Viscount Goderich between 1827 and 1833, the name by which he is best known to history, was a British politician during the Regency era. He was Prime Minister of the United Kingdom between August 1827 and January 1828.

When the Prime Minister, George Canning, died in 1827 Goderich succeeded him, but was unable to hold together Canning's fragile coalition of moderate Tories and Whigs. He resigned after 144 days in office, the shortest in history for any British prime minister who did not die in office.

Arthur Wellesley, 1st Duke of Wellington, (1 May 1769 – 14 September 1852) was an Anglo-Irish soldier and Tory statesman who was one of the leading military and political figures of 19th-century Britain, serving twice as Prime Minister. His victory against Napoleon at the Battle of Waterloo in 1815 puts him in the first rank of Britain's military heroes.

His term as PM was marked by Catholic emancipation: the granting of almost full civil rights to Catholics in Great Britain and Ireland. The change was prompted by the landslide by-election win of Daniel O'Connell, an Irish Catholic proponent of emancipation, who was elected despite not being legally allowed to sit in Parliament. In the House of Lords, facing stiff opposition, Wellington spoke for Catholic Emancipation, and according to some sources, gave one of the best speeches of his career.

William IV was King of the United Kingdom of Great Britain and Ireland from 26 June 1830 until his death in 1837. The third son of George III, William succeeded his elder brother George IV, becoming the last king and penultimate monarch of Britain's House of Hanover.

William served in the Royal Navy in his youth and was nicknamed the "Sailor King". In 1789, he was created Duke of Clarence and St Andrews. In 1827, he was appointed as Britain's first Lord High Admiral since 1709. As his two older brothers died without leaving legitimate issue, he inherited the throne when he was 64 years old. His reign saw several reforms: the poor law was updated, child labour restricted, slavery abolished in nearly all of the British Empire, and the British electoral system refashioned by the Reform Act 1832. He was the last monarch to appoint a prime minister contrary to the will of Parliament.

At the time of his death William had no surviving legitimate children. He was succeeded by his niece Victoria and in Hanover by his brother Ernest Augustus.

Charles Grey, 2nd Earl Grey, (13 March 1764 – 17 July 1845), known as Viscount Howick between 1806 and 1807, was a member of the Whig Party and was a long-time leader of multiple reform movements, most famously the Reform Act 1832. His government also saw the abolition of slavery in the British Empire, in which the government purchased slaves from their owners in 1833. Grey was a strong opponent of the foreign and domestic policies of William Pitt the Younger in the 1790s. In 1807, he resigned as foreign secretary to protest the King's uncompromising rejection of Catholic Emancipation. Grey finally resigned in 1834 over disagreements in his cabinet regarding Ireland, and retired from politics.

Earl Grey tea is named after him.

James Clerk Maxwell (13 June 1831 – 5 November 1879) was a Scottish scientist in the field of mathematical physics. His most notable achievement was to formulate the classical theory of electromagnetic radiation, bringing together for the first time electricity, magnetism, and light as different manifestations of the same phenomenon. Maxwell's equations for electromagnetism have been called the "second great unification in physics" after the first one realised by Isaac Newton.

His discoveries helped usher in the era of modern physics, laying the foundation for such fields as special relativity and quantum mechanics. Many physicists regard Maxwell as the 19th C scientist having the greatest influence on 20th C physics. On the centenary of Maxwell's birthday, Einstein described Maxwell's work as the "most profound and the most fruitful that physics has experienced since the time of Newton".

The Black Hawk War was a brief conflict between the United States and Native Americans led by Black Hawk, a Sauk leader. The war erupted soon after Black Hawk and a group of Sauks, Meskwakis, and Kickapoos, known as the "British Band", crossed the Mississippi River, into the U.S. state of Illinois, from Iowa Indian Territory in April 1832. Black Hawk's motives were ambiguous, but he was apparently hoping to avoid bloodshed while resettling on tribal land that had been ceded to the United States in the disputed 1804 Treaty of St. Louis.

The war gave the young captain Abraham Lincoln his brief military service, although he never participated in a battle. Other participants who later became famous included Winfield Scott, Zachary Taylor, and Jefferson Davis. The war gave impetus to the U.S. policy of Indian removal, in which Native American tribes were pressured to sell their lands and move west of the Mississippi River and stay there.

The Slavery Abolition Act abolished slavery in the British Empire. This Act expanded the jurisdiction of the Slave Trade Act 1807 which made the purchase or ownership of slaves illegal within the British Empire, with the exception "of the Territories in the Possession of the East India Co", Ceylon (Sri Lanka), & Saint Helena. The Act was repealed in 1997 as part of a review of English statute but later anti-slavery legislation remains

In 1832, a Royal Commission into the Poor Law recommended changes to the system of parish poor relief. Many of its recommendations were incorporated into the Poor Law Amendment Act of 1834.

This statute maintained outdoor relief (relief given outside a workhouse), but led to more central control of the system

The Workhouse originated in the Poor Law Act 1388 but mass unemployment after the Napoleonic Wars, & the introduction of technology to replace agricultural workers meant the established system was unsustainable. The Poor Law of 1834 discouraged the provision of relief to anyone who refused to enter a workhouse. Life in a workhouse was harsh but in the provision of free medical care & education for children inmates were advantaged over the general population

William Lamb, 2nd Viscount Melbourne, (15 March 1779 – 24 November 1848) was a British Whig statesman who served as Home Secretary (1830–1834) and Prime Minister (1834 and 1835–1841). He is best known for his intense and successful mentoring of Queen Victoria in the ways of politics, when she was between the ages of 18 and 21. Historians have concluded that Melbourne does not rank highly as a Prime Minister, for there were no great foreign wars or domestic issues to handle, he lacked major achievements, and he enunciated no grand principles. "But he was kind, honest and not self-seeking."

Melbourne was Prime Minister on two occasions. The first ended when he was dismissed by King William IV in 1834, the last British prime minister to be dismissed by a monarch. Six months later he was re-appointed and served for six years.

Arthur Wellesley, 1st Duke of Wellington, (1 May 1769 – 14 September 1852) was an Anglo-Irish soldier and Tory statesman who was one of the leading military and political figures of 19th-century Britain, serving twice as Prime Minister. His victory against Napoleon at the Battle of Waterloo in 1815 puts him in the first rank of Britain's military heroes.

This, his second term as PM, was a caretaker role until a new leader was found.

Sir Robert Peel, 2nd Baronet, (5 February 1788 – 2 July 1850) was a British statesman and Conservative Party politician who served twice as Prime Minister of the United Kingdom (1834–35 and 1841–46) and twice as Home Secretary (1822–27 and 1828–30). He is regarded as the father of modern British policing and as one of the founders of the modern Conservative Party.

His first administration was a minority government, dependent on Whig support and with Peel serving as his own Chancellor of the Exchequer. After only four months, his government collapsed and he served as Leader of the Opposition during the second government of the Viscount Melbourne (1835–1841).

William Lamb, 2nd Viscount Melbourne, (15 March 1779 – 24 November 1848) was a British Whig statesman who served as Home Secretary (1830–1834) and Prime Minister (1834 and 1835–1841). He is best known for his intense and successful mentoring of Queen Victoria in the ways of politics, when she was between the ages of 18 and 21. Historians have concluded that Melbourne does not rank highly as a Prime Minister, for there were no great foreign wars or domestic issues to handle, he lacked major achievements, and he enunciated no grand principles. "But he was kind, honest and not self-seeking."

Melbourne was Prime Minister on two occasions. The first ended when he was dismissed by King William IV in 1834, the last British prime minister to be dismissed by a monarch. Six months later he was re-appointed and served for six years.

Victoria was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death. On 1 May 1876, she adopted the additional title of Empress of India.

Victoria inherited the throne at the age of 18, after her father's three elder brothers had all died leaving no surviving legitimate children. She became a national icon who was identified with strict standards of personal morality. Victoria married her first cousin Prince Albert. After his death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result, republicanism temporarily gained strength but in the latter half of her reign, her popularity recovered. Her Golden and Diamond Jubilees were times of public celebration.

Before 1837, there was no national system of civil registration in England and Wales. Baptisms, marriages and burials were recorded in parish registers maintained by Church of England clergy. With the increase in nonconformity baptisms, marriages and burials were going unrecorded. The Parochial Registers Act of 1812 did not recognise the church registers of Nonconformists. Eventually, this led to the 1836 Registration and Marriage Acts

More correctly known as the Palace of Westminster, the Houses of Parliament are the meeting places of the Houses of Commons and Lords. The name is from the neighbouring Westminster Abbey.While the present buildings make look as though they date from the Gothic Period of the 14th and 15th Centuries, they were built between 1840 and 1870 following the 1834 fire

British Migration to New Zealand: In early 19th C, Britain conditions were such that millions set off for the New World. By 1839 there were only 2,000 immigrants in New Zealand, by 1852, 28,000. The decisive moment for this change was 1840 when the Treaty of Waitangi was signed. This established British authority in European eyes, and gave British immigrants legal rights as citizens. The treaty helped ensure that for 100+ years, most immigrants would come from the UK

Sir Robert Peel, 2nd Baronet, (5 February 1788 – 2 July 1850) was a British statesman and Conservative Party politician who served twice as Prime Minister of the United Kingdom (1834–35 and 1841–46) and twice as Home Secretary (1822–27 and 1828–30). He is regarded as the father of modern British policing and as one of the founders of the modern Conservative Party.

His second government ruled for five years. He cut tariffs to stimulate trade; to replace the lost revenue he pushed through a 3% income tax. He played a central role in making free trade a reality and set up a modern banking system.

Following the end of the Napoleonic War in 1815, the public mood of compliance with income tax rapidly evaporated. The government wanted to retain it to help reduce the National Debthowever, strong public opposition to the tax was demonstrated by landowners, merchants, manufacturers, bankers, and tradesmen. On 18 March 1816, the government was narrowly defeated on the issue and was forced to abandon it.

By the early 1840s business opinion had moved towards 'free trade' and the removal of high protective duties on imports and exports. Sir Robert Peel, the Prime Minister, was keen to facilitate this thinking. In 1842, therefore, he re-introduced income tax at 7d in the pound on incomes over £150. This allowed him to remove import and export duties on more than 700 items.

Sir John Bennet Lawes, 1st Baronet, FRS (28 December 1814 – 31 August 1900) was an English entrepreneur and agricultural scientist. He founded an experimental farm at his home at Rothamsted Manor that eventually became the Rothamsted Experimental Station, where he developed and, in 1842, patented a superphosphate that would mark the beginnings of the chemical fertilizer industry

SS Great Britain is a museum ship and former passenger steamship, and was advanced for her time. She was the longest passenger ship in the world from 1845 to 1854. She was designed by Isambard Kingdom Brunel (1806–1859), for the Great Western Steamship Company's transatlantic service between Bristol and New York. While other ships had been built of iron or equipped with a screw propeller, the Great Britain was the first to combine these features in a large ocean-going ship. She was the first iron steamer to cross the Atlantic, which she did in 1845, in 14 days.

John Russell, 1st Earl Russell, (18 August 1792 – 28 May 1878), known by his courtesy title Lord John Russell before 1861, was a leading Whig and Liberal politician who served as Prime Minister of the United Kingdom on two occasions during the early Victorian era.

He headed a government that failed to deal with the Irish Potato Famine, a disaster which saw the loss of a quarter of that country's population. It has been said that his ministry of 1846 to 1852 was the ruin of the Whig party: it never composed a Government again, and his ministry of 1865 to 1866 was very nearly the ruin of the Liberal Party also.

Alexander Graham Bell was a Scottish-born scientist, inventor, engineer, and innovator who is credited with inventing and patenting the first practical telephone. He also founded the American Telephone and Telegraph Company (AT&T) in 1885.

Bell's father, grandfather, and brother had all been associated with work on elocution and speech and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone in 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study

The Great Exhibition of the Works of Industry of All Nations or The Great Exhibition, sometimes referred to as the Crystal Palace Exhibition in reference to the temporary structure in which it was held, was an international exhibition that took place in Hyde Park, London, from 1 May to 15 October 1851. It was the first in a series of World's Fairs, exhibitions of culture and industry that became popular in the 19th century, and it was a much anticipated event. It was organized by Henry Cole and Prince Albert, husband of the reigning monarch, Queen Victoria. It was attended by famous people of the time,

Edward George Geoffrey Smith-Stanley, 14th Earl of Derby, (29 March 1799 – 23 October 1869) was a British statesman, three-time Prime Minister of the United Kingdom and, to date, the longest-serving leader of the Conservative Party. He was known before 1834 as Edward Stanley, and from 1834 to 1851 as Lord Stanley. He is one of only four British prime ministers to have three or more separate periods in office. However, his ministries all lasted less than two years and totalled three years and 280 days.

Derby formed a minority government in February 1852 following the collapse of Lord John Russell's Whig Government. When the aged Duke of Wellington, by then very deaf, heard the list of inexperienced cabinet ministers being read aloud in the House of Lords, he gave the government its nickname by shouting "Who? Who?" From then this government would be known as the "Who, Who" government

George Hamilton-Gordon, 4th Earl of Aberdeen, (28 January 1784 – 14 December 1860), was a British statesman, diplomat and landowner, successively a Tory, Conservative and Peelite politician, who served as Prime Minister from 1852 until 1855 in a coalition between the Whigs and Peelites, with Radical and Irish support.

The Aberdeen ministry was filled with powerful and talented politicians, whom Aberdeen was largely unable to control and direct. Despite trying to avoid this happening, it took Britain into the Crimean War, and fell when its conduct became unpopular, after which Aberdeen retired from politics.

The Crimean War was fought by an alliance of Britain, France, Turkey and Sardinia against Russian expansion into the Danube region (modern day Romania). One battle - The Battle of Balaclava - became famous for the Charge of the Light Brigade

The Crimean war also saw the rise to prominence of Florence Nightingale.

Henry John Temple, 3rd Viscount Palmerston, (20 October 1784 – 18 October 1865) was a British statesman who served twice as Prime Minister in the mid-19th century. Palmerston dominated British foreign policy during the period 1830 to 1865, when Britain was at the height of her imperial power. He held office almost continuously from 1807 until his death in 1865. He began his parliamentary career as a Tory, defected to the Whigs in 1830, and became the first Prime Minister of the newly formed Liberal Party in 1859.

He had two periods in office, 1855–1858 and 1859–1865, before his death at the age of 80 years, a few months subsequent to victory in a general election in which he had achieved an increased majority. He remains, to date, the last Prime Minister to die in office.

Edward George Geoffrey Smith-Stanley, 14th Earl of Derby, (29 March 1799 – 23 October 1869) was a British statesman, three-time Prime Minister of the United Kingdom and, to date, the longest-serving leader of the Conservative Party. He was known before 1834 as Edward Stanley, and from 1834 to 1851 as Lord Stanley. He is one of only four British prime ministers to have three or more separate periods in office. However, his ministries all lasted less than two years and totalled three years and 280 days.

Among the notable achievements of this, his second administration, was the end of the British East India Company following the Sepoy Mutiny, which brought India under direct British control for the first time. Once again the government was short-lived, resigning after only one year, having narrowly lost a vote of no-confidence

Sir Arthur Conan Doyle was Scottish author who created the legendary character, 'Sherlock Holmes.' He wrote over 60 'Sherlock Holmes' stories and many non-fiction, works of fantasy, science-fiction, poetry and historical novels. He went to medical school and set up his own practice. His medical career did not succeed and he began writing while he waited for patients. The rest is history.

Henry John Temple, 3rd Viscount Palmerston, (20 October 1784 – 18 October 1865) was a British statesman who served twice as Prime Minister in the mid-19th century. Palmerston dominated British foreign policy during the period 1830 to 1865, when Britain was at the height of her imperial power. He held office almost continuously from 1807 until his death in 1865. He began his parliamentary career as a Tory, defected to the Whigs in 1830, and became the first Prime Minister of the newly formed Liberal Party in 1859.

He had two periods in office, 1855–1858 and 1859–1865, before his death at the age of 80 years, a few months subsequent to victory in a general election in which he had achieved an increased majority. He remains, to date, the last Prime Minister to die in office.

On the Origin of Species (or more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life), published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.

The history of the London Underground began with the construction of the Metropolitan Railway, the world's first underground railway which opened in 1863 using gas-lit wooden carriages hauled by steam locomotives. The Metropolitan eventually extended more than 50 miles from Baker Street, London. By 1907 the District and Metropolitan Railways had electrified the underground sections of their lines.

John Russell, 1st Earl Russell, (18 August 1792 – 28 May 1878), known by his courtesy title Lord John Russell before 1861, was a leading Whig and Liberal politician who served as Prime Minister of the United Kingdom on two occasions during the early Victorian era.

When Palmerston suddenly died in late 1865, Russell again became Prime Minister. His second premiership was short and frustrating, and Russell failed in his great ambition of expanding the franchise, a task that would be left to his Conservative successors, Derby and Benjamin Disraeli. In 1866, party disunity again brought down his government.

Edward George Geoffrey Smith-Stanley, 14th Earl of Derby, (29 March 1799 – 23 October 1869) was a British statesman, three-time Prime Minister of the United Kingdom and, to date, the longest-serving leader of the Conservative Party. He was known before 1834 as Edward Stanley, and from 1834 to 1851 as Lord Stanley. He is one of only four British prime ministers to have three or more separate periods in office. However, his ministries all lasted less than two years and totalled three years and 280 days.

Derby returned to power for the third and last time in 1866. This administration was particularly notable for the passage of the Reform Act 1867, which greatly expanded the suffrage but which provoked the resignation of three cabinet ministers including the Secretary for India and three-time future Prime Minister, Lord Cranborne (later Lord Salisbury).

Marie Skłodowska Curie; born Maria Salomea Skłodowska 7 November 1867 – 4 July 1934) was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and only woman to win twice, and the only person to win a Nobel Prize in two different sciences. She was part of the Curie family legacy of five Nobel Prizes. She was also the first woman to become a professor at the University of Paris, and in 1995 became the first woman to be entombed on her own merits in the Panthéon in Paris.

She was born in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaw's clandestine Flying University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her older sister Bronisława to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work. She shared the 1903 Nobel Prize in Physics with her husband Pierre Curie and physicist Henri Becquerel. She won the 1911 Nobel Prize in Chemistry.

Benjamin Disraeli, 1st Earl of Beaconsfield, (21 December 1804 – 19 April 1881) was a British statesman who twice served as Prime Minister of the United Kingdom.

During his first term of office, the Conservatives remained a minority in the House of Commons and the passage of the Reform Bill required the calling of a new election once the new voting register had been compiled. Disraeli's term as Prime Minister, which began in February 1868, would therefore be short.

William Ewart Gladstone (29 December 1809 – 19 May 1898) was a British statesman and Liberal Party politician. In a career lasting over sixty years, he served for twelve years as Prime Minister of the United Kingdom, spread over four terms beginning in 1868 and ending in 1894.

Many reforms were passed during his first ministry, including the disestablishment of the Church of Ireland and the introduction of secret voting. After electoral defeat in 1874, Gladstone resigned as leader of the Liberal Party.

The 1870 Education Act stands as the very first piece of legislation to deal specifically with the provision of education in Britain. Most importantly, it demonstrated a commitment to provision on a national scale.

The Act allowed voluntary schools to carry on unchanged, but established a system of 'school boards' to build and manage schools in areas where they were needed. The boards were locally elected bodies which drew their funding from the local rates. Unlike the voluntary schools, religious teaching in the board schools was to be 'non-denominational'. A separate Act extended similar provisions to Scotland in 1872.

Ernest Rutherford was a New Zealand physicist known as the father of nuclear physics.

He received the Nobel Prize in Chemistry in 1908 “for his investigations into the disintegration of the elements & the chemistry of radioactive substances.” He identified & named the Alpha & Beta

Benjamin Disraeli, 1st Earl of Beaconsfield, (21 December 1804 – 19 April 1881) was a British statesman who twice served as Prime Minister of the United Kingdom.

Disraeli's new government enacted many reforms, including: - the Artisans' and Labourers' Dwellings Improvement Act 1875, which made inexpensive loans available to towns and cities to construct working-class housing. - the Public Health Act 1875, modernising sanitary codes through the nation, - the Sale of Food and Drugs Act (1875) - the Education Act (1876). - the Factory Act meant to protect workers, - the Conspiracy, and Protection of Property Act 1875, which allowed peaceful picketing - the Employers and Workmen Act (1875) to enable workers to sue employers in the civil courts if they broke legal contracts.

As a result of these social reforms the Liberal-Labour MP Alexander Macdonald said, "The Conservative party have done more for the working classes in five years than the Liberals have in fifty."

"Mr. Watson — Come here — I want to see you" were the first intelligible words spoken over the telephone, as recorded in Bell's Journal entry (10 March 1876). These are often misquoted as "Mr. Watson, come here, I want you." Watson later recounted that Bell had spilled battery acid and had called for him over the phone with these words, but this may have been in a separate incident.

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). His work is also known for its influence on the philosophy of science.

He is best known to the general public for his mass–energy equivalence formula E = mc2, which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory.

William Ewart Gladstone (29 December 1809 – 19 May 1898) was a British statesman and Liberal Party politician. In a career lasting over sixty years, he served for twelve years as Prime Minister of the United Kingdom, spread over four terms beginning in 1868 and ending in 1894.

Historians have debated the wisdom of Gladstone's foreign-policy during his second ministry. Paul Hayes says it "provides one of the most intriguing and perplexing tales of muddle and incompetence in foreign affairs, unsurpassed in modern political history until the days of Grey and, later, Neville Chamberlain."

Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish physician, microbiologist, and pharmacologist. His best-known discoveries are the enzyme lysozyme in 1923 and the world's first antibiotic substance benzylpenicillin (Penicillin G) from the mould Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain. He wrote many articles on bacteriology, immunology, and chemotherapy.

A prime meridian, based at the Royal Observatory, Greenwich, in London was established by Sir George Airy in 1851. By 1884, over two-thirds of all ships and tonnage used it as the reference meridian on their charts and maps. In October of that year, at the behest of US President Chester A. Arthur, 41 delegates from 25 nations met in Washington, D.C., United States, for the International Meridian Conference. This conference selected the meridian passing through Greenwich as the official prime meridian due to its popularity. However, France abstained from the vote, and French maps continued to use the Paris meridian for several decades.

Robert Arthur Talbot Gascoyne-Cecil, 3rd Marquess of Salisbury, (3 February 1830 – 22 August 1903), styled Lord Robert Cecil before 1865 and Viscount Cranborne from June 1865 until April 1868, was a British statesman and Conservative Party politician, serving as Prime Minister three times for a total of over thirteen years. He was the last Prime Minister to head his full administration from the House of Lords.

He became Prime Minister of a minority administration from 1885 to 1886. In the November 1883 issue of National Review Salisbury wrote an article titled "Labourers' and Artisans' Dwellings" in which he argued that the poor conditions of working class housing were injurious to morality and health

William Ewart Gladstone (29 December 1809 – 19 May 1898) was a British statesman and Liberal Party politician. In a career lasting over sixty years, he served for twelve years as Prime Minister of the United Kingdom, spread over four terms beginning in 1868 and ending in 1894.

During this administration he first introduced his Home Rule Bill for Ireland. The issue split the Liberal Party (a breakaway group went on to create the Liberal Unionist party) and the bill was thrown out on the second reading, ending his government after only a few months and inaugurating another headed by Lord Salisbury.

Robert Arthur Talbot Gascoyne-Cecil, 3rd Marquess of Salisbury, (3 February 1830 – 22 August 1903), styled Lord Robert Cecil before 1865 and Viscount Cranborne from June 1865 until April 1868, was a British statesman and Conservative Party politician, serving as Prime Minister three times for a total of over thirteen years. He was the last Prime Minister to head his full administration from the House of Lords.

In 1889 Salisbury set up the London County Council and then in 1890 allowed it to build houses. However, he came to regret this, saying in November 1894 that the LCC, "is the place where collectivist and socialistic experiments are tried. It is the place where a new revolutionary spirit finds its instruments and collects its arms".

John Logie Baird (13 August 1888 – 14 June 1946) was a Scottish engineer, innovator, one of the inventors of the mechanical television, demonstrating the first working television system on 26 January 1926, and inventor of both the first publicly demonstrated colour television system, and the first purely electronic colour television picture tube.

In 1928 the Baird Television Development Company achieved the first transatlantic television transmission. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history.
