Partition of Ireland
Beginning on 21 January 1919 with the Soloheadbeg ambush, through the Irish War of Independence, Irish republicans attempted to bring about the secession of Ireland from the United Kingdom of Great Britain and Ireland. Meanwhile, Irish unionistsmost of whom lived in the northeast of the islandwere just as determined to maintain the Union. The British Government, committed to implementing Home Rule, set up a cabinet committee under the chairmanship of southern unionist Walter Long. The Long Committee recommended the establishment of two devolved administrations, dividing the island into two territories: Northern Ireland and Southern Ireland. This was implemented as the Government of Ireland Act 1920. The act entered into force as a "" on 3 May 1921 and provided that Northern Ireland would consist of the six northeastern counties, while the remainder of the island would form Southern Ireland. It was intended that each jurisdiction would be granted home rule but remain within the United Kingdom. The government of Southern Ireland never functioned: the war for independence continued until the two sides agreed a truce in July 1921, ending with the Anglo-Irish Treaty on 6 December 1921.
Foreign relations of Ireland
Since at least the 1600s Ireland has had political connections with the United Kingdom, with the whole island becoming a part of the United Kingdom of Great Britain and Ireland from 1801 to 1922. From the time of Ireland declaring itself independent from the United Kingdom in 1937, the two countries have been involved in a dispute over the status of Northern Ireland. Articles 2 and 3 of the Constitution of Ireland formerly claimed Northern Ireland as a part of the ""national territory"", though in practice the Irish government did recognise the UK's jurisdiction over the region.
From the onset of the Troubles in 1969, the two governments sought to bring the violence to an end. The Sunningdale Agreement of 1973 and the Anglo-Irish Agreement of 1985 were important steps in this process. In 1998, both states signed the Good Friday Agreement and now co-operate closely to find a solution to the region's problems. Articles 2 and 3 of the Constitution of Ireland were amended as part of this agreement, the territorial claim being replaced with a statement of aspiration to unite the people of the island of Ireland. As part of the Good Friday Agreement, the states also ended their dispute over their respective names: "Ireland" and the "United Kingdom of Great Britain and Northern Ireland". Each agreed to accept and use the others' correct name.
