of November 1800, illustrating the new arms, flag, and royal standard of the United Kingdom The Acts of Union were two complementary Acts, namely: • The Union with Ireland Act 1800 (39 & 40 Geo. 3 c. 67), an Act of the
Parliament of Great Britain, and • The Act of Union (Ireland) 1800 (40 Geo. 3 c. 38), an Act of the
Parliament of Ireland. They were passed on 2 July 1800 and 1 August 1800 respectively, and came into force on 1 January 1801. They ratified eight articles which had been previously agreed by the British and Irish parliaments: • Articles I–IV dealt with the political aspects of the Union. It created a
united parliament. • In the House of Lords, the existing members of the Parliament of Great Britain were joined by, as
Lords Spiritual, four bishops of the
Church of Ireland, rotating among the dioceses in each session and as
Lords Temporal 28
Irish representative peers elected for life by the
Peerage of Ireland. • The House of Commons was to include the pre-union representation from Great Britain and 100 members from Ireland. :: • Article V united the established
Church of England and Church of Ireland into "one Protestant Episcopal Church, to be called, The United Church of England and Ireland"; but also confirmed the independence of the
Church of Scotland. • Article VI created a
customs union, with the exception that customs duties on certain British and Irish goods passing between the two countries would remain for 10 years (a consequence of having trade depressed by the ongoing war with revolutionary France). The High Court of Northern Ireland ruled that parts of this Article as it applied to the UK were "
impliedly repealed" by the passage of the
European Union (Withdrawal) Act 2020. This decision was upheld on appeal by the
Supreme Court of the United Kingdom. • Article VII stated that Ireland would have to contribute two-seventeenths towards the expenditure of the United Kingdom. The figure was a ratio of Irish to British foreign trade. • Article VIII formalised the legal and judicial aspects of the Union. Part of the appeal of the Union for many Irish Catholics was the promise of
Catholic emancipation, allowing
Roman Catholic MPs, who had not been permitted to sit in the Irish Parliament, to sit in the United Kingdom Parliament. This was however blocked by King
George III who argued that emancipating Roman Catholics would breach his
Coronation Oath, and was not realised until the
Roman Catholic Relief Act 1829. The traditionally separate
Irish Army, which had been funded by the Irish Parliament, was merged into the larger
British Army.
The first parliament In the first Parliament of the United Kingdom of Great Britain and Ireland, the members of the House of Commons were not elected afresh. By royal proclamation authorised by the Act, all the members of the last House of Commons from Great Britain took seats in the new House, and from Ireland
100 members were chosen from the last Irish House of Commons: two members from each of the 32 counties and the two largest boroughs, and one from each of the next 31 largest boroughs and from
Dublin University, chosen by lot. The other 84 Irish parliamentary boroughs were disfranchised; all were
pocket boroughs, whose patrons received £15,000 compensation for the loss of what was considered their property. == Flags and styles==
