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.

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.

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.
