George III in the context of Gold State Coach

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.

Sir Joshua Reynolds (16 July 1723 – 23 February 1792) was an English painter who specialised in portraits. The art critic John Russell called him one of the major European painters of the 18th century, while Lucy Peltz says he was "the leading portrait artist of the 18th-century and arguably one of the greatest artists in the history of art." He promoted the "Grand Style" in painting, which depended on idealisation of the imperfect. He was a founder and first president of the Royal Academy of Arts and was knighted by George III in 1769. He has been referred to as the 'master who revolutionised British Art.'

Reynolds had a famously prolific studio that produced over 2,000 paintings during his lifetime. Ellis Waterhouse estimated those works the painter did ‘think worthy’ at ‘hardly less than a hundred paintings which one would like to take into consideration, either for their success, their originality, or their influence.' Of these, Portrait of Omai is probably his best known work and has been described by Simon Schama as "one of the greatest things British art has ever produced [and] one of the all time, timeless masterpieces that painting can produce." Waterhouse considered The Marlborough Family as 'the most monumental achievement of British portraiture' and that 'Reynolds' genius came to full flower in the diversity and geniality he was able to give to his full-length portraits' like Portrait of Philip Gell and Portrait of the Earl of Carlisle.

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.

James Gillray (13 August 1756 – 1 June 1815) was a British caricaturist and printmaker famous for his etched political and social satires, mainly published between 1792 and 1810. Many of his works are held at the National Portrait Gallery in London.

Gillray has been called "the father of the political cartoon", with his works satirizing George III, Napoleon, prime ministers and generals. Regarded as one of the two most influential cartoonists, the other being William Hogarth, Gillray's wit and humour, knowledge of life, fertility of resource, keen sense of the ludicrous, and beauty of execution, at once gave him the first place among caricaturists.

From 1340, English monarchs, beginning with the Plantagenet king Edward III, asserted that they were the rightful kings of France. They fought the Hundred Years' War (1337–1453), in part, to enforce this claim, but ultimately without success. From the early 16th century, the claim had lost any realistic prospect of fulfilment, although every English and, later, British monarch, from Edward III to George III, styled themselves king or queen of France until 1801.

Edward's claim was through his mother, Isabella, sister of the last direct line Capetian king of France, Charles IV. Women were excluded from inheriting the French crown and Edward was Charles's nearest male relative. On Charles's death in 1328, however, the French magnates supported Philip VI, the first king of the House of Valois, a cadet branch of the Capetian dynasty. Philip was Charles's nearest male line relative. French jurists later argued that it was a fundamental law of the kingdom that the crown could not be inherited through the female line. This was supposedly based on the 6th-century Frankish legal code known as the Salic law, although the link to the Salic law, which was tenuous in any case, was not made until the 15th century.

Saint John (French: Saint-Jean) is a seaport city located on the Bay of Fundy in the province of New Brunswick, Canada. It is Canada's oldest incorporated city, established by royal charter on May 18, 1785, during the reign of George III. The Port of Saint John is Canada's third-largest by tonnage with a cargo base that includes dry and liquid bulk, break bulk, containers, and cruise. The city has a strong industrial base, including oil refining and manufacturing, as well as significant finance and tourism sectors and research institutions such as the New Brunswick Museum and the University of New Brunswick. Saint John was the most populous city in New Brunswick for more than 230 years until the 2016 census, when it was overtaken by Moncton. It is currently the second-largest city in the province, with a population of 69,895 over an area of 315.59 km (121.85 sq mi).

French explorer Samuel de Champlain landed at Saint John Harbour on June 24, 1604, the feast of St. John the Baptist, and named the Saint John River in his honour; the indigenous Mi'kmaq and Wolastoqiyik peoples called the river "Wolastoq". The Saint John area was an important location for trade and defence in Acadia during the French colonial era, and Fort La Tour, in the city's harbour, was a pivotal battleground during the Acadian Civil War.

The Treaty of Paris, signed by representatives of King George III of Great Britain and representatives of the United States on September 3, 1783, officially ended the War of American Independence and recognized the Thirteen Colonies, which had been part of colonial British America, to be free, sovereign and independent unified states.

The treaty set the boundaries between British North America, later called Canada, and the United States, on lines the British labeled as "exceedingly generous," although exact boundary definitions in the far-northwest and to the south continued to be subject to some controversy. Details included fishing rights and restoration of property and prisoners of war.

The British Army during the American Revolutionary War served for eight years of armed conflict, fought in eastern North America, the Caribbean, and elsewhere from April 19, 1775 until the treaty ending the war, September 3, 1783. Britain had no European allies in the war, which was initially between Great Britain and American insurgents in the Thirteen Colonies. The war widened when the American insurgents made a formal alliance with France (1778) and gained the aid of France's ally Spain (1779).

In June 1775, the Second Continental Congress, gathered in present-day Independence Hall in the revolutionary capital of Philadelphia, appointed George Washington commander-in-chief of the Continental Army, which the Congress organized by uniting and organizing patriot militias into a single army under the command of Washington, who led it in its eight-year war against the British Army. The following year, in July 1776, the Second Continental Congress, representing the Thirteen Colonies, unanimously adopted the Declaration of Independence, an iconic and historical document largely written by Thomas Jefferson, addressed to King George III, which articulated why the delegates to the Congress felt were declaring themselves free and independent from the Kingdom of Great Britain. Adoption of the Declaration served to both inspire the cause of independence in the Thirteen Colonies and also formalized and escalated the Revolutionary War.

The Whigs were a political party in the Parliaments of England, Scotland, Ireland, Great Britain and the United Kingdom. Between the 1680s and the 1850s, the Whigs contested power with their rivals, the Tories. The Whigs became the Liberal Party when the faction merged with the Peelites and Radicals in the 1850s. Many Whigs left the Liberal Party in 1886 over the issue of Irish Home Rule to form the Liberal Unionist Party, which merged into the Conservative Party in 1912.

The Whigs began as a political faction that opposed absolute monarchy and Catholic emancipation, supporting constitutional monarchism and parliamentary government, but also Protestant supremacy. They played a central role in the Glorious Revolution of 1688 and were the standing enemies of the Roman Catholic Stuart kings and pretenders. The period known as the Whig Supremacy (1714–1760) was enabled by the Hanoverian succession of George I in 1714 and the failure of the Jacobite rising of 1715 by Tory rebels. The Whigs took full control of the government in 1715 and thoroughly purged the Tories from all major positions in government, the army, the Church of England, the legal profession, and local political offices. The first great leader of the Whigs was Robert Walpole, who maintained control of the government from 1721 to 1742, and whose protégé, Henry Pelham, led the government from 1743 to 1754. Great Britain approximated a one-party state under the Whigs until King George III came to the throne in 1760 and allowed Tories back in; however, the Whig Party's hold on power remained strong for many years thereafter. Historians have called the period from roughly 1714 to 1783 the "long period of Whig oligarchy". During the American War of Independence, the Whigs were the party more sympathetic to American independence and the creation of a democracy in the United States.

Whiggism or Whiggery is a political philosophy that grew out of the Parliamentarian faction in the Wars of the Three Kingdoms (1639–1653) and was concretely formulated by Lord Shaftesbury during the Stuart Restoration. The Whigs advocated the supremacy of Parliament (as opposed to that of the king), government centralisation, and coercive Anglicisation through the educational system. They also staunchly opposed granting freedom of religion, civil rights, or voting rights to anyone who worshipped outside of the Established Churches of the realm. Eventually, the Whigs grudgingly conceded strictly limited religious toleration for Protestant dissenters, while continuing the religious persecution and disenfranchisement of Roman Catholics and Scottish Episcopalians. They were particularly determined to prevent the ascension of a Catholic heir presumptive to the British throne, especially of James II or his legitimate male descendants and instead granted the throne to the Protestant House of Hanover in 1714. Whig ideology is associated with early conservative liberalism.

Beginning with the Titus Oates plot and Exclusion Crisis of 1679–1681, and the Glorious Revolution of 1688–1689, Whiggism dominated English and British politics until about 1760, after which the Whigs splintered into different political factions. In the same year, King George III was crowned and allowed the Tories back into the Government. Even so, some modern historians now call the period between 1714 and 1783 the, "age of the Whig oligarchy".

George IV (George Augustus Frederick; 12 August 1762 – 26 June 1830) was King of the United Kingdom of Great Britain and Ireland and King of Hanover from 29 January 1820 until his death in 1830. At the time of his accession to the throne, he was acting as prince regent for his father, King George III, having done so since 5 February 1811 during his father's final mental illness.

George IV was the eldest child of King George III and Queen Charlotte. He 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 commissioned Jeffry Wyatville to rebuild Windsor Castle. George's 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, Caroline of Brunswick, earned him the contempt of the people and dimmed the prestige of the monarchy. He excluded Caroline from his coronation and asked the government to introduce the unpopular Pains and Penalties Bill in an unsuccessful attempt to divorce her.
