User:DBD/List of Prime Ministers' retirement honours

This is a list of Prime Ministers of the United Kingdom, and its predecessor state the Kingdom of Great Britain, from when the first Prime Minister (in the modern sense), Robert Walpole, took office in 1721, until the present day.

18th century Prime Ministers
Prime Ministers during the 18th century were Prime Minister of England, Wales and Scotland (the Kingdom of Great Britain, formed by the Act of Union 1707).

19th century Prime Ministers
Prime Ministers during the 19th century were Prime Minister of England, Wales, Scotland and Ireland, following the Act of Union 1800 (which merged the Kingdom of Ireland with the Kingdom of Great Britain, forming the United Kingdom of Great Britain and Ireland, as of 1 January, 1801).

20th century Prime Ministers
There was no change in the jurisdiction of the Parliament of the United Kingdom (and hence the area the Prime Minister was Prime Minister of) until 1922, when following the Anglo-Irish War, 26 counties in Ireland seceded from the United Kingdom, forming the Irish Free State. The other 6 counties, in the northeast of Ireland, remained in the Union, becoming Northern Ireland. The official name of the United Kingdom became the United Kingdom of Great Britain and Northern Ireland.
