1921 division of the island into two jurisdictions
The Partition of Ireland () was the process by which the Government of the United Kingdom of Great Britain and Ireland (UK) divided Ireland into two self-governing polities: Northern Ireland and Southern Ireland. It was enacted on 3 May 1921 under the Government of Ireland Act 1920. The Act intended both territories to remain within the United Kingdom and contained provisions for their eventual reunification. The smaller Northern Ireland was duly created with a devolved government (Home Rule) and remained part of the UK. The larger Southern Ireland was not recognised by most of its citizens, who instead recognised the self-declared 32-county Irish Republic. On 6 December 1922 (a year after the signing of the Anglo-Irish Treaty), Ireland was partitioned. At that time, the territory of Southern Ireland left the UK and became the Irish Free State, now known as the Republic of Ireland. Ireland had a large Catholic, nationalist majority who wanted self-governance or independence. Prior to partition the Irish Home Rule movement compelled the British Parliament to introduce bills that would give Ireland a devolved government within the UK (home rule). This led to the Home Rule Crisis (1912–14), when Ulster unionists/loyalists founded a large paramilitary organization (at least 100,000 men), the Ulster Volunteers, that could be used to prevent Ulster from being ruled by an Irish government. The British government proposed to exclude all or part of Ulster, but the crisis was interrupted by the First World War (1914–18). Support for Irish independence grew during the war and after the 1916 armed rebellion known as the Easter Rising.
The Irish republican political party Sinn Féin won the vast majority of Irish seats in the 1918 election. They formed a separate Irish parliament and declared an independent Irish Republic covering the whole island. This led to the Irish War of Independence (1919–21), a guerrilla conflict between the Irish Republican Army (IRA) and British forces. In 1920 the British government introduced another bill to create two devolved governments: one for six northern counties (Northern Ireland) and one for the rest of the island (Southern Ireland). This was passed as the Government of Ireland Act 1920, and came into force as a "" on 3 May 1921. Following the 1921 elections, Ulster unionists formed a Northern Ireland government. A Southern government was not formed, as republicans recognised the Irish Republic instead. During 1920–22, in what became Northern Ireland, partition was accompanied by violence "in defence or opposition to the new settlement" – see The Troubles in Northern Ireland (1920–1922). In the first half of 1922, the IRA launched a failed "Northern Offensive" into border areas of Northern Ireland. The capital, Belfast, saw "savage and unprecedented" communal violence, mainly between Protestant and Catholic civilians. More than 500 were killed and more than 10,000 became refugees, most of them from the Catholic minority.
The Irish War of Independence resulted in a truce in July 1921 and led to the Anglo-Irish Treaty that December. Under the Treaty, the territory of Southern Ireland would leave the UK and become the Irish Free State. Northern Ireland's parliament could vote it in or out of the Free State, and a commission could then redraw or confirm the provisional border. The Northern government chose to remain in the UK. The Boundary Commission proposed small changes to the border in 1925, but they were not implemented.
Since partition, most Irish nationalists/republicans continue to seek a united and independent Ireland, while Ulster unionists/loyalists want Northern Ireland to remain part of the UK. Over the years the Unionist governments of Northern Ireland have been accused of discrimination against the Irish nationalist and Catholic minority. In 1967 Unionists opposed a civil rights campaign to end discrimination, viewing it as a republican front. This helped spark the Troubles (c. 1969–1998), a thirty-year conflict in which more than 3,500 people were killed. Under the 1998 Good Friday Agreement, the Irish and British governments and the main political parties agreed to a power-sharing government in Northern Ireland, and that the status of Northern Ireland would not change without the consent of a majority of its population. The treaty also reaffirmed an open border between both jurisdictions.
Background.
Irish Home Rule movement.
Results in Ireland of the December 1910 United Kingdom general election showing a large majority for the Irish Parliamentary Party.
During the 19th century, the Irish nationalist Home Rule movement campaigned for Ireland to have self-government while remaining part of the United Kingdom. The nationalist Irish Parliamentary Party won most Irish seats in the 1885 general election. It then held the balance of power in the British House of Commons, and entered into an alliance with the Liberals. IPP leader Charles Stewart Parnell convinced British Prime Minister William Gladstone to introduce the First Irish Home Rule Bill in 1886. Protestant unionists in Ireland opposed the Bill, fearing industrial decline and religious persecution of Protestants by a Catholic-dominated Irish government. English Conservative politician Lord Randolph Churchill proclaimed: "the Orange card is the one to play", in reference to the Protestant Orange Order. The belief was later expressed in the popular slogan, "Home Rule means Rome Rule". Partly in reaction to the Bill, there were riots in Belfast, as Protestant unionists attacked the city's Catholic nationalist minority. The Bill was defeated in the Commons.
Gladstone introduced a Second Irish Home Rule Bill in 1892. The Irish Unionist Alliance had been formed to oppose home rule, and the Bill sparked mass unionist protests. In response, Liberal Unionist leader Joseph Chamberlain called for a separate provincial government for Ulster where Protestant unionists were a majority. Irish unionists assembled at conventions in Dublin and Belfast to oppose both the Bill and the proposed partition. The unionist MP Horace Plunkett, who would later support home rule, opposed it in the 1890s because of the dangers of partition. Although the Bill was approved by the Commons, it was defeated in the House of Lords.
Home Rule Crisis.
Following the December 1910 election, the Irish Parliamentary Party again agreed to support a Liberal government if it introduced another home rule bill. The Parliament Act 1911 meant the House of Lords could no longer veto bills passed by the Commons, but only delay them for up to two years. British Prime Minister H. H. Asquith introduced the Third Home Rule Bill in April 1912. An amendment to the Bill was introduced calling for the partition of Ireland. In June 1912 Asquith spoke in Parliament rejecting the suggestion of partition: ;templatestyles src="Template:Blockquote/styles.css" / ;"You can no more split Ireland into parts than you can split England or Scotland into parts...You have an essential unity of race and temperament, although I agree that unhappily dissensions have been rank, partially by religion, and partially, by the organisation of partisanship. The more Irishmen are encouraged and empowered to cooperate in the great works of governing their own country, the more convinced am I that these differences will disappear."
Unionists opposed the Bill, but argued that if Home Rule could not be stopped then all or part of Ulster should be excluded from it. Irish nationalists opposed partition, although some were willing to accept Ulster having some self-governance within a self-governing Ireland ("Home Rule within Home Rule"). Winston Churchill made his feelings about the possibility of the partition of Ireland clear: "Whatever Ulster's right may be, she cannot stand in the way of the whole of the rest of Ireland. Half a province cannot impose a permanent veto on the nation. Half a province cannot obstruct forever the reconciliation between the British and Irish democracies." The 1911 census reported Catholic majorities in five of the nine counties of Ulster, two of the Catholic majority counties (Tyrone and Fermanagh) would later be incorporated into Northern Ireland. In September 1912, more than 500,000 Unionists signed the Ulster Covenant, pledging to oppose Home Rule by any means and to defy any Irish government. They founded a large paramilitary movement, the Ulster Volunteers, to prevent Ulster becoming part of a self-governing Ireland. They also threatened to establish a Provisional Ulster Government. In response, Irish nationalists founded the Irish Volunteers to ensure Home Rule was implemented. The Ulster Volunteers smuggled 25,000 rifles and three million rounds of ammunition into Ulster from the German Empire, in the Larne gun-running of April 1914. The Irish Volunteers also smuggled weaponry from Germany in the Howth gun-running that July. On 20 March 1914, in the "Curragh incident", many of the highest-ranking British Army officers in Ireland threatened to resign rather than deploy against the Ulster Volunteers. This meant that the British government could legislate for Home Rule but could not be sure of implementing it. Ireland seemed to be on the brink of civil war.
Exclusion of Ulster.
In May 1914, the British government introduced an amending bill to the Third Home Rule Act allowing for the "temporary exclusion of Ulster" from Home Rule. Some Ulster unionists were willing to tolerate the 'loss' of some mainly-Catholic areas of the province (the Ulster counties of Monaghan, Cavan and Donegal). In May 1914 three border boundary options were proposed for the temporary exclusion of part of Ulster from Home Rule. One option recommended that Counties Tyrone and Fermanagh, south County Armagh, south County Down, the cities of Newry and Derry should be left under the proposed Irish Parliament. There was then debate over how much of Ulster should be excluded and for how long, and whether to hold referendums in each county. The Chancellor of the Exchequer Lloyd George supported "the principle of the referendum...each of the Ulster Counties is to have the option of exclusion from the Home Rule Bill." In July 1914, King George V called the Buckingham Palace Conference to allow Unionists and Nationalists to come together and discuss the issue of partition, but the conference achieved little. After much negotiations in 1914, John Redmond the leader of the largest political party in Ireland (the Irish Parliamentary Party) agreed to the temporary exclusion of some areas of Ulster. In June 1916 (after the Easter Rising) Lloyd George asked for Redmonds approval for six counties (now to include Tyrone and Fermanagh) to be temporarily excluded (four counties had been requested in 1912 and 1914). Redmond was assured by the British Prime Minister and the entire Cabinet that voters in all counties excluded from Home Rule would be permitted to vote on joining a Home Rule Ireland (a vote was never held). Redmond was also "guaranteed" that all excluded counties were to be returned to Home Rule Ireland after six years. On 20 July 1916 Redmond was removed from any further negotiations with the British government. He spoke on the floor of the House of Commons: ;templatestyles src="Template:Blockquote/styles.css" / ;I was informed, on behalf of the Cabinet, that negotiations and communications and consultations with me had been struck off, and that I would receive no communication from the Cabinet until they had come to a decision, behind my back, upon proposals which I had never seen and which they refused to submit to me. I asked them what the nature of these new proposals was, and I was told that the Cabinet did not desire to consult me about them, and until they had come to a decision I would be told nothing...The next communication I received was on Saturday last, when the Minister for War and the Home Secretary requested me to call and see them at the War Office. They then informed me that another Cabinet Council had been held, and that it had been decided, mark you, decided, to insert in the Bill two entirely new provisions, one providing for the permanent exclusion of Ulster, of the six Ulster counties...and I was given to understand in so many words that this decision was not put before me for the purpose of discussion or consultation, that the decision was absolute and final, and the right hon. Gentlemen described themselves to me simply as messengers, without any power or authority to discuss these questions in any way whatever with me, and they informed me that it was the intention of the Government to introduce a Bill containing these provisions practically whether we liked it or not.
