George III in the context of "Joshua Reynolds"

William IV (William Henry; 21 August 1765 – 20 June 1837) was King of the United Kingdom of Great Britain and Ireland and King of Hanover 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 the United Kingdom's House of Hanover.

William served in the Royal Navy in his youth, spending time in British North America and the Caribbean, and was later nicknamed the "Sailor King". In 1789, he was created Duke of Clarence and St Andrews. Between 1791 and 1811, he cohabited with the actress Dorothea Jordan, with whom he had ten children. In 1818, he married Princess Adelaide of Saxe-Meiningen. In 1827, he was appointed Britain's Lord High Admiral, the first since 1709.

The American Revolution (1765–1783) was a political conflict involving the Thirteen Colonies and Great Britain, culminating in the American Revolutionary War and the independence of the colonies as the United States. The Second Continental Congress established the Continental Army and appointed George Washington as its commander-in-chief in 1775. The following year, the Congress unanimously adopted the Declaration of Independence. Throughout most of the war, the outcome appeared uncertain. However, in 1781, a decisive victory by Washington and the Continental Army in the Siege of Yorktown led King George III and the British to negotiate the cessation of colonial rule and the acknowledgment of American independence, formalized in the Treaty of Paris in 1783.

Discontent with colonial rule began shortly after the French and Indian War in 1763. Even though the colonies had fought in and supported the war, the British Parliament imposed new taxes to compensate for wartime costs and transferred control of the colonies' western lands to British officials in Montreal. Representatives from several colonies convened the Stamp Act Congress in 1765; its "Declaration of Rights and Grievances" argued that taxation without representation violated their rights as Englishmen. In 1767, tensions flared again following British Parliament's passage of the Townshend Acts. In an effort to quell the mounting rebellion, King George III deployed British troops to Boston, where they killed protesters in the Boston Massacre in 1770. In December 1773, Sons of Liberty activists instigated the Boston Tea Party, during which they dumped chests of tea owned by the British East India Company into Boston Harbor. London responded by enacting a series of punitive laws, which effectively ended self-government in Massachusetts but also intensified the revolutionary cause.

The Declaration of Independence, formally The unanimous Declaration of the thirteen united States of America in the original printing, is the founding document of the United States. On July 4, 1776, it was adopted unanimously by the Second Continental Congress, who were convened at Pennsylvania State House, later renamed Independence Hall, in the colonial city of Philadelphia. These delegates became known as the nation's Founding Fathers. The Declaration explains why the Thirteen Colonies regarded themselves as independent sovereign states no longer subject to British colonial rule, and has become one of the most circulated, reprinted, and influential documents in history.

The American Revolutionary War commenced in April 1775 with the Battles of Lexington and Concord. Amid the growing tensions, the colonies reconvened the Congress on May 10. Their king, George III, proclaimed them to be in rebellion on August 23. On June 11, 1776, Congress appointed the Committee of Five (John Adams, Benjamin Franklin, Thomas Jefferson, Robert R. Livingston, and Roger Sherman) to draft and present the Declaration. Adams, a leading proponent of independence, persuaded the committee to charge Jefferson with writing the document's original draft, which the Congress then edited. Jefferson largely wrote the Declaration between June 11 and June 28, 1776. The Declaration was a formal explanation of why the Continental Congress voted to declare American independence from the Kingdom of Great Britain. Two days prior to the Declaration's adoption, Congress passed the Lee Resolution, which resolved that the British no longer had governing authority over the Thirteen Colonies. The Declaration justified the independence of the colonies, citing 27 colonial grievances against the king and asserting certain natural and legal rights, including a right of revolution.

The American Revolutionary War (April 19, 1775 – September 3, 1783), also known as the Revolutionary War or American War of Independence, was the armed conflict that comprised the final eight years of the broader American Revolution, in which American Patriot forces organized as the Continental Army and commanded by George Washington defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war, but Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 led King George III and the Kingdom of Great Britain to negotiate an end to the war. In 1783, in the Treaty of Paris, the British monarchy acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation.

In 1763, after the British Empire gained dominance in North America following its victory over the French in the Seven Years' War, tensions and disputes began escalating between the British and the Thirteen Colonies, especially following passage of Stamp and Townshend Acts. The British Army responded by seeking to occupy Boston militarily, leading to the Boston Massacre on March 5, 1770. In mid-1774, with tensions escalating even further between the British Army and the colonies, the British Parliament imposed the Intolerable Acts, an attempt to disarm Americans, leading to the Battles of Lexington and Concord in April 1775, the first battles of the Revolutionary War. In June 1775, the Second Continental Congress voted to incorporate colonial-based Patriot militias into a central military, the Continental Army, and unanimously appointed Washington its commander-in-chief. Two months later, in August 1775, the British Parliament declared the colonies to be in a state of rebellion. In July 1776, the Second Continental Congress formalized the war, passing the Lee Resolution on July 2, and, two days later, unanimously adopting the Declaration of Independence, on July 4.

The Treaty of Kiel (Danish: Kieltraktaten) or Peace of Kiel (Swedish and Norwegian: Kielfreden or freden i Kiel) was concluded between the United Kingdom of Great Britain and Ireland and the Kingdom of Sweden on one side and the Kingdoms of Denmark and Norway on the other side on 14 January 1814 in Kiel. It ended the hostilities between the parties in the ongoing Napoleonic Wars, where the United Kingdom and Sweden were part of the anti-French camp (the Sixth Coalition) while Denmark–Norway was allied to the French Empire.

Frederick VI of Denmark joined the anti-French alliance, ceded Heligoland to George III of the United Kingdom, and further ceded the Kingdom of Norway to Charles XIII of Sweden in return for Swedish Pomerania. Specifically excluded from the exchange were the Norwegian dependencies of Greenland, Iceland and the Faroe Islands, which remained in the union with Denmark. (Norway would unsuccessfully contest the Danish claim to all of Greenland in the Eastern Greenland Case of 1931–1933.)

The Regency era of British history is commonly understood as the years between c. 1795 and 1837, although the official regency for which it is named only spanned the years 1811 to 1820. King George III first suffered debilitating illness in the late 1780s, and relapsed into his final mental illness in 1810. By the Regency Act 1811, his eldest son George, Prince of Wales, was appointed Prince Regent to discharge royal functions. The Prince had been a major force in Society for decades. When George III died in 1820, the Prince Regent succeeded him as George IV. In terms of periodisation, the longer timespan is roughly the final third of the Georgian era (1714–1837), encompassing the last 25 years or so of George III's reign, including the official Regency, and the complete reigns of both George IV and his brother and successor William IV. It ends with the accession of Queen Victoria in June 1837 and is followed by the Victorian era (1837–1901).

Although the Regency era is remembered as a time of refinement and culture, that was the preserve of the wealthy few, especially those in the Prince Regent's own social circle. For the masses, poverty was rampant as urban population density rose due to industrial labour migration. City dwellers lived in increasingly larger slums, a state of affairs severely aggravated by the combined impact of war, economic collapse, mass unemployment, a bad harvest in 1816 (the "Year Without a Summer"), and an ongoing population boom. Political response to the crisis included the Corn Laws, the Peterloo Massacre, and the Representation of the People Act 1832. Led by William Wilberforce, there was increasing support for the abolitionist cause during the Regency era, culminating in passage of the Slave Trade Act 1807 and the Slavery Abolition Act 1833.

Giovanni Antonio Canal (18 October 1697 – 19 April 1768), commonly known as Canaletto (Italian: [kanaˈletto]), was an Italian painter from the Republic of Venice, considered an important member of the 18th-century Venetian school.

Painter of cityscapes or vedute, of Venice, Rome, and London, he also painted imaginary views (referred to as capricci), although the demarcation in his works between the real and the imaginary is never quite clearcut. He was further an important printmaker using the etching technique. In the period from 1746 to 1756, he worked in England, where he painted many views of London and other sites, including Warwick Castle and Alnwick Castle. He was highly successful in England, thanks to the British merchant and connoisseur Joseph "Consul" Smith, whose large collection of Canaletto's works was sold to King George III in 1762.

The Georgian era was a period in British history from 1714 to 1837, named after the Hanoverian kings George I, George II, George III and George IV. The definition of the Georgian era is also often extended to include the relatively short reign of William IV, which ended with his death in 1837. The subperiod that is the Regency era is defined by the regency of George IV as Prince of Wales during the illness of his father George III. The term Georgian is typically used in the contexts of social and political history and architecture. The term Augustan literature is often used for Augustan drama, Augustan poetry and Augustan prose in the period 1700–1740s. The term Augustan refers to the acknowledgement of the influence of Latin literature from the ancient Roman Republic. The term Georgian era is not applied to the time of the two 20th-century British kings of this name, George V and George VI. Those periods are simply referred to as Georgian.

When Victoria became Queen in 1837 the Georgian era was followed by the Victorian era. The Victorians emphasized moral earnestness and propriety, as well as industrial and scientific progress and scientific advancement. There was a growing tension between faith and doubt and more Realism in literature and art (moving away from Romantic idealism).

Victoria (Alexandrina Victoria; 24 May 1819 – 22 January 1901) was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death. Her reign of 63 years and 216 days, which was longer than those of any of her predecessors, constituted the Victorian era, a period of industrial, political, scientific, and military change within the United Kingdom marked by a great expansion of the British Empire. In 1876, the British parliament voted to grant her the additional title of Empress of India.

Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn (the fourth son of King George III), and Princess Victoria of Saxe-Coburg-Saalfeld. After the deaths of her father and grandfather in 1820, she was raised under close supervision by her mother and her comptroller, John Conroy. She inherited the throne aged 18 after her father's three elder brothers died without surviving legitimate issue. Victoria attempted privately to influence government policy and ministerial appointments; publicly, she became a national icon who was identified with strict standards of personal morality.
