Partition of Ireland
By the end of the war (during which the 1916 Easter Rising had taken place), most Irish nationalists now wanted full independence rather than home rule. In September 1919, British Prime Minister David Lloyd George tasked a committee with planning another home rule bill. Headed by English unionist politician Walter Long, it was known as the 'Long Committee'. It decided that two devolved governments should be established—one for the nine counties of Ulster and one for the rest of Ireland—together with a Council of Ireland for the "encouragement of Irish unity". Most Ulster unionists wanted the territory of the Ulster government to be reduced to six counties so that it would have a larger Protestant unionist majority, which they believed would guarantee its longevity. The six counties of Antrim, Down, Armagh, Londonderry, Tyrone and Fermanagh comprised the maximum area unionists believed they could dominate, The area that was to become Northern Ireland included counties Fermanagh and Tyrone, even though they had nationalist majorities in the 1918 Irish general election.Events overtook the government. In the 1918 Irish general election, the pro-independence Sinn Féin party won the overwhelming majority of Irish seats. Sinn Féin's elected members boycotted the British parliament and founded a separate Irish parliament (Dáil Éireann), declaring an independent Irish Republic covering the whole island. Many Irish republicans blamed the British establishment for the sectarian divisions in Ireland, and believed that Ulster unionism would fade once British rule was ended. The British authorities outlawed the Dáil in September 1919, and a guerrilla conflict developed as the Irish Republican Army (IRA) began attacking British forces. This became known as the Irish War of Independence.Meanwhile, the Government of Ireland Act 1920 passed through the British parliament in 1920. It would divide Ireland into two self-governing UK territories: the six northeastern counties (Northern Ireland) being ruled from Belfast, and the other twenty-six counties (Southern Ireland) being ruled from Dublin. Both would have a shared Lord Lieutenant of Ireland, who would appoint both governments and a Council of Ireland, which the UK government intended to evolve into an all-Ireland parliament. The Act received royal assent that December, becoming the Government of Ireland Act 1920. It came into force on 3 May 1921, partitioning Ireland and creating Northern Ireland. the 1921 Irish elections were held on 24 May, in which unionists won most seats in the Northern Ireland parliament. It first met on 7 June and formed its first devolved government, headed by Ulster Unionist Party leader James Craig. Irish nationalist members refused to attend. King George V addressed the ceremonial opening of the Northern parliament on 22 June.During 1920–22, in what became Northern Ireland, partition was accompanied by violence "in defence or opposition to the new settlement" during the Troubles in Northern Ireland (1920–1922). The IRA carried out attacks on British forces in the north-east but was less active than in the rest of Ireland. Protestant loyalists attacked Catholics in reprisal for IRA actions. In the summer of 1920, sectarian violence erupted in Belfast and Derry, and there were mass burnings of Catholic property in Lisburn and Banbridge. Conflict continued intermittently for two years, mostly in Belfast, which saw "savage and unprecedented" communal violence between Protestants and Catholics, including rioting, gun battles, and bombings. Homes, businesses, and churches were attacked and people were expelled from workplaces and mixed neighbourhoods. More than 500 were killed and more than 10,000 became refugees, most of them Catholics. The British Army was deployed and the Ulster Special Constabulary (USC) was formed to help the regular police. The USC was almost wholly Protestant. Members of the USC and regular police were involved in reprisal attacks on Catholic civilianss. A truce between British forces and the IRA was established on 11 July 1921, ending the fighting in most of Ireland. However, communal violence continued in Belfast, and in 1922 the IRA launched a guerrilla offensive along the new Irish border.The Anglo-Irish Treaty was signed between representatives of the governments of the UK and the Irish Republic on 6 December 1921, creating the Irish Free State. Under the terms of the treaty, Northern Ireland would become part of the Free State unless its government opted out by presenting an address to the king, although in practice partition remained in place.
