 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.

The Parliament of Great Britain was formed in 1707 following the ratification of the Acts of Union by both the Parliament of England and the Parliament of Scotland.
 The Acts created a new unified Kingdom of Great Britain and dissolved the separate English and Scottish parliaments in favour of a single parliament, located in the former home of the English parliament in the Palace of Westminster, near the City of London.
 This lasted nearly a century, until the Acts of Union 1800 merged the separate British and Irish Parliaments into a single Parliament of the United Kingdom with effect from 1 January 1801.
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 The "Irish" Act (the Act of the (Old) Irish Parliament) however has since been repealed in the Republic of Ireland some time after Independence.
The Irish House of Lords was the upper house of the Parliament of Ireland that existed from medieval times until 1800.
 It was modelled on the House of Lords of England, with members of the Peerage of Ireland sitting in the Irish Lords, just as members of the Peerage of England did at Westminster.
 When the Act of Union 1800 abolished the Irish parliament, a subset of Irish peers sat in the House of Lords of the merged Parliament of the United Kingdom.
