August 2nd , 1800
The Acts of Union 1800 merged the Kingdom of Ireland and Kingdom of Great Britain into the United Kingdom of Great Britain and Ireland.
The parliament was merged with that of Great Britain; the united Parliament was in effect the British parliament at Westminster enlarged with a subset of the Irish Lords and Commons.
Irish Members of Parliament and peers now took their seats in the Palace of Westminster and Parliament House was sold to Bank of Ireland.
The terms of the union were agreed on 28 March 1800 by both houses of the Irish Parliament.
Two Acts with identical aims (but with different wording) were passed in both the British and Irish parliaments, with the British Act of Union becoming law on 2 July 1800, and royal assent given to the Irish Act of Union on 1 August 1800.
The Irish Parliament met for the last time the following day on August 2nd, 1800.
