Charles I was king of England, Scotland and Ireland, whose conflicts with parliament led to civil war and his eventual execution.

Charles's reign was plagued with tensions with parliament over money - made worse by the costs of war abroad. In addition, Charles favoured a High Anglican form of worship, and his wife was Catholic - both made many of his subjects suspicious, particularly the Puritans. In November 1641, tensions were raised even further with disagreements over who should command an army to suppress an uprising in Ireland. Charles attempted to have five members of parliament arrested and in August 1642, raised the royal standard at Nottingham. Civil war began.

The Royalists were defeated by the Scots and the formation of the New Model Army. Convinced that there would never be peace while the king lived, a rump of radical MPs, including Cromwell, put him on trial for treason. He was found guilty and executed on 30 January 1649 outside the Banqueting House on Whitehall, London.

Sir Christopher Wren is best known for the design of St Paul's Cathedral, London. After the 1666 Great Fire of London destroyed most of the city, the king appointed him as one of the architectural commissioners to oversee the rebuilding of the city. Over the next 46 years, Wren designed and supervised the rebuilding of 51 city churches including his masterpiece, St. Paul’s Cathedral

The English Civil War (1642–1651) was a series of armed conflicts between Parliamentarians ("Roundheads") and Royalists ("Cavaliers") over the manner of England's governance. The first (1642–1646) and second (1648–1649) wars pitted the supporters of King Charles I against the supporters of the Long Parliament, while the third (1649–1651) saw fighting between supporters of King Charles II and supporters of the Rump Parliament. The war ended with the Parliamentarian victory at the Battle of Worcester on 3 September 1651.

The outcome was threefold: the trial and execution of Charles I (1649); the exile of his son, Charles II (1651); and the replacement of English monarchy with the Commonwealth of England (1649–1653) and then the Protectorate under the personal rule of Oliver Cromwell (1653–1658) and his son Richard (1658–1659). Constitutionally, the wars established that an English monarch cannot govern without Parliament's consent.

Sir Isaac Newton FRS PRS (25 December 1642 – 20 March 1726/27 was an English mathematician, physicist, astronomer, theologian, and author (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time, and a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations of classical mechanics. Newton also made seminal contributions to optics, and shares credit with Gottfried Wilhelm Leibniz for developing the infinitesimal calculus.

Oliver Cromwell (25 April 1599 – 3 September 1658) was an English military and political leader. He served as Lord Protector of the Commonwealth of England, Scotland, and Ireland from 1653 until his death, acting simultaneously as head of state and head of government of the new republic.

Cromwell was one of the signatories of King Charles I's death warrant in 1649. He died from natural causes in 1658 and was buried in Westminster Abbey. The Royalists returned to power along with King Charles II in 1660, and they had his corpse dug up, hung in chains, and beheaded.

Edmond Halley was a British astronomer and mathematician, known for calculating the orbit of Halley’s Comet. He went St Helena to make a list of the southern stars. He created a catalogue of 341, which he published as ‘Catalogus Stellarum Australium’. It instantly established him as a leading astronomer, earning him a fellowship at the Royal Society and a M.A. degree from Oxford

Richard Cromwell (4 October 1626 – 12 July 1712) became the second Lord Protector of England, Scotland and Ireland, and was one of only two commoners to become the English head of state, the other being his father, Oliver Cromwell, from whom he inherited the post on his father's death. But but he lacked authority and he formally renounced power nine months after succeeding. Without a king-like figure, such as Oliver Cromwell, as head of state the government lacked coherence and legitimacy.

Although a Royalist revolt was crushed by recalled civil war figure General John Lambert, who then prevented the Rump Parliament from reconvening and created a Committee of Safety, he found his troops melted away in the face of General George Monck's advance from Scotland. Monck then presided over the Restoration of 1660.

After the execution of his father, Prince Charles spent the next nine years in exile in France, the Dutch Republic and the Spanish Netherlands. A political crisis that followed the death of Cromwell in 1658 resulted in the restoration of the monarchy, and Charles was invited to return to Britain. On 29 May 1660, his 30th birthday, he was received in London to public acclaim and crowned Charles II. After 1660, all legal documents were dated as if he had succeeded his father as king in 1649.

Charles was one of the most popular and beloved kings of England, known as the Merry Monarch, in reference to both the liveliness and hedonism of his court and the general relief at the return to normality after over a decade of rule by Cromwell and the Puritans. Charles's wife, Catherine of Braganza, bore no live children, but Charles acknowledged at least twelve illegitimate children by various mistresses. He was succeeded by his brother James

Although the Black Death and had been known in England for centuries, the Great Plague killed an estimated 100,000 people - almost a quarter of London's population - in 18 months. King Charles II and his court left London and fled to Oxford.

At that time, bubonic plague was a much feared disease but its cause was not understood. Some blamed emanations from the earth, "pestilential effluviums", unusual weather, sickness in livestock, abnormal behaviour of animals or an increase in the numbers of moles, frogs, mice or flies. It was not until 1894 that the identification by Alexandre Yersin of its causal agent Yersinia pestis was made and the transmission of the bacterium by rat fleas became known.

The people of London who had managed to survive the Great Plague of the previous year must have thought that 1666 could only be better, then on 2 September in a bakery near London Bridge, a fire started … the Great Fire of London.

The fire gutted the medieval City of London inside the old Roman city wall. It threatened but did not reach the aristocratic district of Westminster, Charles II's Palace of Whitehall, and most of the suburban slums. It consumed 13,200 houses, 87 parish churches, St Paul's Cathedral, and most of the buildings of the City authorities. It is estimated to have destroyed the homes of 70,000 of the City's 80,000 inhabitants. The death toll is unknown but was thought to be small, as only six verified deaths were recorded. This has recently been challenged because the deaths of poor and middle-class people were not recorded; moreover, the heat of the fire may have cremated many victims, leaving no recognisable remains.

James II of England and Ireland, and James VII of Scotland reigned from 6 February 1685 until he was deposed in the Glorious Revolution of 1688. He was the last Roman Catholic monarch of England, Scotland and Ireland.

The second surviving son of Charles I, he ascended the throne upon the death of his brother, Charles II. Members of Britain's Protestant political elite suspected him of being pro-French and pro-Catholic and of having designs on becoming an absolute monarch. When he produced a Catholic heir, a son called James, leading nobles called on his Protestant son-in-law and nephew William III of Orange to invade, which he did in the Glorious Revolution of 1688. James fled England. He was replaced by his Protestant daughter Mary. James made one serious attempt to recover his crowns from William and Mary when he landed in Ireland in 1689. After the defeat of the Jacobite forces by the Williamites at the Battle of the Boyne in July 1690, James returned to France.

William III, supported by a group of influential British political and religious leaders, invaded England in what became known as the "Glorious Revolution," landing at the southern English port of Brixham. James was deposed and William and his wife became joint sovereigns. William and Mary reigned together until Mary's death on 28 December 1694, after which William ruled as sole monarch.

William's reputation as a staunch Protestant enabled him to take power in Britain when many were fearful of a revival of Catholicism. Hiss victory at the Battle of the Boyne in 1690 is still commemorated by loyalists in Northern Ireland and Scotland. His reign marked the beginning of the transition from the personal rule of the Stuarts to a more Parliament-centred rule

Mary II (30 April 1662 – 28 December 1694) was Queen of England, Scotland, and Ireland, reigning with her husband, King William III of England and Ireland, and King William II of Scotland. William and Mary, both Protestants, became king and queen after the Glorious Revolution, which resulted in the adoption of the English Bill of Rights and the deposition of her Roman Catholic father, James II and VII. William became sole ruler upon her death in 1694.

Mary wielded less power than William when he was in England, ceding most of her authority to him, though he heavily relied on her. She acted alone when William was engaged in military campaigns abroad, proving herself to be a powerful, firm, and effective ruler.

Queen Anne, the second daughter of James II, Anne was a staunch, high church Protestant. During her reign Britain became a major military power and the foundations were laid for the 18th century’s Golden Age.

Anne was plagued by ill health throughout her life, and from her thirties, she grew increasingly ill and obese. Despite seventeen pregnancies by her husband, Prince George of Denmark, she died without surviving issue and was the last monarch of the House of Stuart. Under the Act of Settlement 1701, which excluded all Catholics, she was succeeded by her second cousin George I of the House of Hanover.
