The 'United Kingdom of Great Britain and Ireland' was the formal name of the
United Kingdom from
1 January 1801 until
12 April 1927. It was formed by the merger of the
Kingdom of Great Britain (itself having been a merger of the Kingdoms of
England and
Scotland) and the
Kingdom of Ireland.
Following
Irish independence on
6 December 1922, when the 1921
Anglo-Irish Treaty came into effect, the name continued in official use until it was changed to the
United Kingdom of Great Britain and Northern Ireland by the
Royal and Parliamentary Titles Act of 1927. That part of the island of Ireland which seceded from the United Kingdom of Great Britain and Ireland in 1922 today constitutes the
Republic of Ireland.
Origins
The merger of the two kingdoms followed the
Irish Rebellion of 1798. The rebellion, which shook the
Protestant Ascendancy in Ireland, was met with brutality on behalf of the government resulting in the death of up to 30,000 at government hands through massacres, atrocities and terrors. The rebellion had been preceded by a century of
discriminatory rule in Ireland, where the overwhelming majority of the population were excluded or limited from public and economic life. As a result of this, the London government pushed the merger largely in response to the perception that the rebellion was provoked as much by the brutish misrule of the Ascendancy as by the efforts of the revolutionaries.
To some measure, a crisis over the mental health of King
George III, given that both separate kingdoms could in theory appoint different
regents. The union was enacted by means of the
Act of Union, passed by both the
Irish Parliament and the
British Parliament.
Terms of the Union

George III, the first king of the new United Kingdom.
Under the terms of the merger, the separate Parliaments of
Great Britain and
Ireland were abolished, and replaced by a united
Parliament of the United Kingdom.
[1] The new
House of Commons consisted of all
Members of Great Britain's
18th Parliament and 100 Irish MPs
co-opted in a special
election in 1801.
The new
House of Lords consisted of all members of Great Britain's House of Lords, and 4
Lords Spiritual and 28
Lords Temporal from the
Irish House of Lords.
1 The new Parliament met in the
Palace of Westminster, formerly the home of the Parliament of Great Britain and, until 1707, the
Parliament of England.
Part of the trade-off for Irish Catholics was to be the granting of
Catholic Emancipation, which had been fiercely resisted by the all-
Anglican Irish Parliament. However, this was blocked by
King George III who argued that emancipating Roman Catholics would breach his
Coronation Oath.
The United Kingdom
The Act of Union was initially seen favourably in Ireland, given that the old Irish parliament was seen as hostile to the majority Catholic population, some of whose members had only been given the vote as late as 1794 and who were legally debarred from election to the body. The
Roman Catholic hierarchy endorsed the Union. However King George III's decision to block Catholic Emancipation fatally undermined the appeal of the Union. Leaders like
Henry Grattan who sat in the new parliament, having been leading members of the old one, were bitterly critical.
The eventual achievement of
Catholic Emancipation in 1829, following a campaign by
Daniel O'Connell,
MP for
County Clare, who had won election to Westminster and who could not for religious beliefs take the
Oath of Supremacy, removed the main negative that had undermined the appeal of the old parliament, the exclusion of Catholics. From 1829 on a demand grew again for a native Irish parliament separate from Westminster. However, his campaign to repeal the Act of Union ultimately failed.
==Irish
Devolution==
Later leaders, such as
Charles Stewart Parnell the first leader of the
Irish Parliamentary Party, campaigned for a version of All-Ireland self-government called
Home Rule within the United Kingdom, which was nearly achieved in the 1880s under the (British) ministry of
William Ewart Gladstone who introduced two
Irish Home Rule Bills. However, the measures were defeated in Parliament, and following the ascension of the
Conservatives to the majority, the issue was buried as long as that party was in power.
With the return to power of the
Liberals in 1910 supported by the Irish Party under
John Redmond who now held the balance of power in the Commons, the veto power of the
Lords was removed under the
Parliament Act and an Home Rule Bill introduced in 1912 passed Parliament as the
Third Home Rule Act in 1914, but was temporarily suspended for the duration of
World War I. However the constant delaying of Home Rule and the opposition of the
Orange Order in
Ulster created the frustration that eventually led to political violence and the 1916
Easter Rising. The
European situation changed the political climate such that in the
1918 general election, the Irish Party lost most of its seats to the new
Sinn Féin party.
Breakdown of the Union
In 1919, Sinn Féin MPs elected to Westminster formed a unilaterally independent Irish parliament in
Dublin,
Dáil Éireann with an executive under the
President of Dáil Éireann,
Éamon de Valera. A
War of Independence was fought between 1919 and 1921. Since 1918 the British Government had gone ahead with its commitment to introduce Home Rule to Ireland, and on the
23 December 1920 a Fourth Home Rule Act along the recommendations of the earlier
Irish Convention was passed by the British parliament, the
Government of Ireland Act 1920, resulting in the
Partition of Ireland into two national provinces, called
Northern Ireland and
Southern Ireland. Finally, on
6 December 1922, a year after the
Anglo-Irish Treaty was signed, the twenty-six Southern Ireland counties seceded from the United Kingdom of Great Britain and Ireland and formed the autonomous
Irish Free State. The six counties forming
Northern Ireland remained in the United Kingdom.
Thereafter, the United Kingdom of Great Britain and Ireland continued in name until 1927 when it was renamed as the
United Kingdom of Great Britain and Northern Ireland by the
Royal and Parliamentary Titles Act 1927.
Legacy
Despite increasing political independence from each other from 1922, and complete political independence since 1949, the union left the two countries intertwined with each other in many respects. Ireland used the
Irish Pound from 1928 until 2001 when it was replaced by the
Euro. Until it joined the
ERM in 1979, the Irish pound was
directly linked to the
Pound Sterling.
Decimalisation of both currencies occurred simultaneously on
Decimal Day in 1971. Coins of equivalent value had the same dimensions and size until the introduction of the
British Twenty Pence coin in 1982, the first new coin to be issued since the break with Sterling. British coinage, therefore,
although technically not legal tender in the
Republic of Ireland was in wide circulation and
''usually'' acceptable as payment. The new
British Twenty Pence coin and later
British One Pound coin were the notable exceptions to this, as there was initially no equivalent Irish
coin value, and when subsequently, Irish coins of these values were introduced, their designs differed significantly, thereby not allowing for "stealth" passing of the coins in change.
Irish Citizens in the UK have a status almost equivalent to
British Citizens. They can vote in all elections and even stand for
parliament. As well as this, some people born in the
Republic of Ireland before 1949, but after 3rd March 1922, are
British Subjects.
British Citizens have similar rights to Irish Citizens in the Republic of Ireland and can vote in all elections apart from
Presidential Elections and referendums. People from Northern Ireland can have dual nationality by applying for an
Irish passport in addition to, or instead of a
British one.
List of monarchs
Though the United Kingdom of Great Britain and Ireland came to an end in 1922, the monarch continued to use the title of ''King'' or ''Queen of United Kingdom of Great Britain and Ireland'' until 1927. Then, under the Royal and Parliamentary Titles Act 1927, new titles were introduced for the British monarch so that he would reign as
King of the United Kingdom of Great Britain and Northern Ireland, in the United Kingdom of Great Britain and Northern Ireland, and
King of Ireland, in the Irish Free State.
