when did ireland gain independence and establish a unified government
History of Ireland In 1922, after the Irish War of Independence and the Anglo-Irish Treaty, most of Ireland seceded from the United Kingdom to become the independent Irish Free State, which after the 1937 constitution, began to call itself Ireland. The six northeastern counties, known as Northern Ireland, remained within the United Kingdom. The Irish Civil War followed soon after the War of Independence. The history of Northern Ireland has since been dominated by sporadic sectarian conflict between (mainly Catholic) Irish nationalists and (mainly Protestant) unionists. This conflict erupted into the Troubles in the late 1960s, until peace was achieved with the Belfast Agreement thirty years later.
Northern Ireland Northern Ireland was created in 1921, when Ireland was partitioned between Northern Ireland and Southern Ireland by the Government of Ireland Act 1920. Unlike Southern Ireland, which would become the Irish Free State in 1922, the majority of Northern Ireland's population were unionists, who wanted to remain within the United Kingdom.[15] Most of these were the Protestant descendants of colonists from Great Britain. However, a significant minority, mostly Catholics, were nationalists who wanted a united Ireland independent of British rule.[16][17][18][19] Today, the former generally see themselves as British and the latter generally see themselves as Irish, while a distinct Northern Irish or Ulster identity is claimed both by a large minority of Catholics and Protestants and by many of those who are non-aligned.[20]
Republic of Ireland In accordance with the treaty, on 6 December 1922 the entire island of Ireland became a self-governing dominion called the Irish Free State (Saorstát Éireann). Under the Constitution of the Irish Free State, the Parliament of Northern Ireland had the option to leave the Irish Free State one month later and return to the United Kingdom. During the intervening period, the powers of the Parliament of the Irish Free State and Executive Council of the Irish Free State did not extend to Northern Ireland. Northern Ireland exercised its right under the treaty to leave the new dominion and rejoined the United Kingdom on 8 December 1922. It did so by making an address to the King requesting, "that the powers of the Parliament and Government of the Irish Free State shall no longer extend to Northern Ireland."[26] The Irish Free State was a constitutional monarchy sharing a monarch with the United Kingdom and other dominions of the British Commonwealth. The country had a governor-general (representing the monarch), a bicameral parliament, a cabinet called the "Executive Council", and a prime minister called the President of the Executive Council.
Irish War of Independence Both sides agreed to a ceasefire (or 'truce') on 11 July 1921. In May, Ireland was partitioned under British law by the Government of Ireland Act, which created Northern Ireland. The post-ceasefire talks led to the signing of the Anglo-Irish Treaty on 6 December 1921. This ended British rule in most of Ireland and, after a ten-month transitional period overseen by a provisional government, the Irish Free State was created as a self-governing dominion on 6 December 1922. Northern Ireland remained within the United Kingdom. After the ceasefire, political and sectarian violence between republicans (usually Catholics) and loyalists (usually Protestants) continued in Northern Ireland for many months. In June 1922, disagreement among republicans over the Anglo-Irish Treaty led to the Irish Civil War which lasted for eleven months. The Irish Free State awarded 62,868 medals for service during the War of Independence, of which 15,224 were issued to IRA fighters of the flying columns.[11]
