Partition of IrelandThe partition of Ireland (críochdheighilt na hÉireann) was the process by which the Government of the United Kingdom of Great Britain and Ireland 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.
Ulster loyalismUlster loyalism is a strand of Ulster unionism associated with working class Ulster Protestants in Northern Ireland. Like other unionists, loyalists support the continued existence of Northern Ireland (and formerly all of Ireland) within the United Kingdom, and oppose a united Ireland independent of the UK. Unlike other strands of unionism, loyalism has been described as an ethnic nationalism of Ulster Protestants and "a variation of British nationalism".
Curragh incidentThe Curragh incident of 20 March 1914, sometimes known as the Curragh mutiny, occurred in the Curragh, County Kildare, Ireland. The Curragh Camp was then the main base for the British Army in Ireland, which at the time still formed part of the United Kingdom of Great Britain and Ireland. Ireland was scheduled to receive a measure of devolved government, which included Ulster, later in the year. The incident is important in 20th-century Irish history, and is notable for being one of the few occasions since the English Civil War in which elements of the British military openly intervened in politics.
Irish Home Rule movementThe Home Rule movement was a movement that campaigned for self-government (or "home rule") for Ireland within the United Kingdom of Great Britain and Ireland. It was the dominant political movement of Irish nationalism from 1870 to the end of World War I. Isaac Butt founded the Home Government Association in 1870. This was succeeded in 1873 by the Home Rule League, and in 1882 by the Irish Parliamentary Party. These organisations campaigned for home rule in the British House of Commons.
