Context paragraphs:
Governance of England: There has not been a government of England since 1707 when the Kingdom of England ceased to exist as a sovereign state, as it merged with the Kingdom of Scotland to form the Kingdom of Great Britain.  Kingdom of Great Britain continued from 1707 until 1801 when it merged with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland, which itself became the United Kingdom of Great Britain and Northern Ireland (UK) in 1922 (in reality; in name in 1927) upon independence for most of the island of Ireland.  The UK since then has gone through significant change to its system of government, with devolved parliaments, assemblies and governments in Scotland, Wales and Northern Ireland.  England, however, remains under the full jurisdiction, on all matters, of the Parliament of the United Kingdom of Great Britain and Northern Ireland and the UK government as no devolved administration has been created for England within the new structure.  This situation has led to the anomaly, known as the West Lothian question, which is that Scottish Members of Parliament (MPs) are able to vote on legislation that affects only England whereas English MPs can not vote on certain Scottish matters due to devolution.  In some cases, such as top-up university tuition fees and foundation hospitals, the votes of Scottish MPs have been crucial in helping pass legislation for England that the majority of English MPs have opposed.

List of British monarchs: There have been 12 monarchs of the Kingdom of Great Britain and the United Kingdom (see Monarchy of the United Kingdom) since the merger of the Kingdom of England and the Kingdom of Scotland on 1 May 1707.  England and Scotland had been in personal union under the House of Stuart since 24 March 1603.  On 1 January 1801, Great Britain merged with the Kingdom of Ireland (also previously in personal union with Great Britain) to form the United Kingdom of Great Britain and Ireland.  After most of Ireland left the union on 6 December 1922, its name was amended on 12 April 1927 to the United Kingdom of Great Britain and Northern Ireland.

Monarchy of Ireland: A monarchical system of government existed in Ireland from ancient times until, for what became the Republic of Ireland, the mid-twentieth century.  Northern Ireland, as part of the United Kingdom, remains under a monarchical system of government.  The Gaelic kingdoms of Ireland ended with the Norman invasion of Ireland, when the kingdom became a fief of the Holy See under the Lordship of the King of England.  This lasted until the Parliament of Ireland conferred the crown of Ireland upon King Henry VIII of England during the English Reformation.  The monarch of England held the crowns of England and Ireland in a personal union.  The Union of the Crowns in 1603 expanded the personal union to include Scotland.  The personal union between England and Scotland became a political union with the enactments of the Acts of Union 1707, which created the Kingdom of Great Britain.  The crowns of Great Britain and Ireland remained in personal union until it was ended by the Acts of Union 1800, which united Ireland and Great Britain into the United Kingdom of Great Britain and Ireland from January 1801 until December 1922.

Charlotte of Mecklenburg-Strelitz: Charlotte of Mecklenburg-Strelitz (Sophia Charlotte; 19 May 1744 – 17 November 1818) was by marriage to King George III the Queen of Great Britain and Ireland from her wedding in 1761 until the union of the two kingdoms in 1801, after which she was Queen of the United Kingdom of Great Britain and Ireland until her death in 1818.  She was also the Electress of Hanover in the Holy Roman Empire until the promotion of her husband to King of Hanover on 12 October 1814, after which she was also queen consort of Hanover.

Acts of Union 1800: The Acts of Union 1800 (sometimes erroneously referred to as a single Act of Union 1801) united the Kingdom of Great Britain and the Kingdom of Ireland (previously in personal union) to create the United Kingdom of Great Britain and Ireland with effect from 1 January 1801.  The "Irish" Act (the Act of the (Old) Irish Parliament) however has since been repealed in the Republic of Ireland some time after Independence.

Charlotteville (disambiguation): Charlotteville is the name of places that have usually been named after Charlotte of Mecklenburg-Strelitz, the queen consort of United Kingdom's King George III (1738-1820).

British general election, 1796: The British general election, 1796, returned members to serve in the 18th and last House of Commons of the Parliament of Great Britain to be summoned before the formation of the United Kingdom of Great Britain and Ireland on 1 January 1801.  The members in office in Great Britain at the end of 1800 continued to serve in the first Parliament of the United Kingdom 1801–1802.

United Kingdom of Great Britain and Ireland: The United Kingdom of Great Britain and Ireland was established as a sovereign state on 1 January 1801 by the Acts of Union 1800, which merged the kingdoms of Great Britain and Ireland.  The growing desire for an Irish Republic led to the Irish War of Independence, which resulted in Ireland seceding from the Union and forming the Irish Free State in 1922.  Northern Ireland remained part of the United Kingdom, and the state was consequently renamed the "United Kingdom of Great Britain and Northern Ireland".

George III of the United Kingdom: George III (George William Frederick; 4 June 1738 – 29 January 1820) was King of Great Britain and Ireland from 25 October 1760 until the union of the two countries on 1 January 1801, after which he was King of the United Kingdom of Great Britain and Ireland until his death.  He was concurrently Duke and prince-elector of Brunswick-Lüneburg ("Hanover") in the Holy Roman Empire until his promotion to King of Hanover on 12 October 1814.  He was the third British monarch of the House of Hanover, but unlike his two predecessors, he was born in Britain, spoke English as his first language, and never visited Hanover.

Irish migration to Great Britain: Irish migration to Great Britain has occurred from the earliest recorded history to the present.  There has been a continuous movement of people between the islands of Ireland and Great Britain due to their proximity.  This tide has ebbed and flowed in response to politics, economics and social conditions of both places.  Ireland was a feudal Lordship of the Kings of England between 1171 and 1541; a Kingdom in personal union with the Kingdom of England and Kingdom of Great Britain between 1542 and 1801; and politically united with Great Britain as the United Kingdom of Great Britain and Ireland between 1801 and 1922.  Today, Ireland is divided between the independent Republic of Ireland and Northern Ireland.
