The Irish general election of 1922 took place in Southern Ireland on 16 June 1922, under the provisions of the 1921 Anglo-Irish Treaty to elect a constituent assembly paving the way for the formal establishment of the Irish Free State.
 For Irish republicans this chose part of the membership of the Third Dáil of the Irish Republic; under the provisions of the treaty it was a provisional parliament replacing the parliament of Southern Ireland.
 From 6 December 1922 it was the Dáil Éireann of the Irish Free State.
The Irish Boundary Commission (Irish: "Coimisiún na Teorainne" ) met in 1924–25 to decide on the precise delineation of the border between the Irish Free State and Northern Ireland.
 The 1921 Anglo-Irish Treaty, which ended the War of Independence, provided for such a commission if Northern Ireland chose to secede from the Irish Free State, an event that occurred as expected two days after the Free State's inception on 6 December 1922.
 The governments of the United Kingdom, of the Irish Free State and of Northern Ireland were to nominate one member each to the commission.
 When the Northern government refused to cooperate, the British government assigned a Belfast newspaper editor to represent Northern Irish interests.
The original Irish Republican Army (IRA) fought a guerrilla war against British rule in Ireland in the Irish War of Independence between 1919 and 1921.
 Following the signing of the Anglo-Irish Treaty on 6 December 1921, the IRA in the 26 counties that were to become the Irish Free State split between supporters and opponents of the Treaty.
 The anti-Treatyites, sometimes referred to by Free State forces as Irregulars, continued to use the name Irish Republican Army (IRA) or in Irish Óglaigh na hÉireann, as did the organisation in Northern Ireland which originally supported the pro-Treaty side (if not the Treaty). "
Óglaigh na hÉireann" was also adopted as the name of the pro-Treaty National Army, and remains the official legal title of the Irish Defence Forces.
 This article deals with the anti-Treaty IRA that fought against the Irish Free State in the Irish Civil War, and with its successors up to 1969, when the IRA split again.
Comhairle na dTeachtaí was an Irish republican parliament established by opponents of the 1921 Anglo-Irish Treaty and the resulting Irish Free State, and viewed by republican legitimatists as a successor to the Second Dáil.
 Members were abstentionist from the Third Dáil established by the pro-Treaty faction.
 Just as the First Dáil established a parallel Irish Republic in opposition to the British Dublin Castle administration, so Comhairle na dTeachtaí attempted to establish a legitimatist government in opposition to the Provisional Government and Government of the Irish Free State established by the Third Dáil.
 This legitimatist government, called the Council of State, had Éamon de Valera as President.
 In 1926 de Valera resigned as President, left the Sinn Féin party and founded Fianna Fáil, which in 1927 entered the Fourth Dáil.
 Comhairle na dTeachtaí, never more than a symbolic body, was thereby rendered defunct.
 In 1930 Cumann na nGaedheal TDs alleged in the Dáil that de Valera had addressed Comhairle na dTeachtaí in December 1926, after the foundation of Fianna Fáil; this was to cast aspersions on de Valera's commitment to the Constitution of the Irish Free State.
The Irish Free State (Irish: "Saorstát Éireann" ] ; 6 December 192229 December 1937) was a state established in 1922 under the Anglo-Irish Treaty of December 1921.
 That treaty ended the three-year Irish War of Independence between the forces of the self-proclaimed Irish Republic, the Irish Republican Army (IRA), and British Crown forces.
The Constitution of the Irish Free State (Irish: "Bunreacht Shaorstáit Eireann" ) was the second constitution of the independent Irish state.
 It was adopted by Act of Dáil Éireann sitting as a constituent assembly on 25 October 1922.
 In accordance with Article 83 of the Constitution, the Irish Free State Constitution Act 1922 of the British Parliament, which came into effect upon receiving the royal assent on 5 December 1922, provided that the Constitution would come into effect upon the issue of a Royal Proclamation, which was done on 6 December 1922.
 In 1937 the Constitution of the Irish Free State was replaced by the modern Constitution of Ireland following a referendum.
The Irish Republic (Irish: "Poblacht na hÉireann" or "Saorstát Éireann" ) was a revolutionary state that declared its independence from the United Kingdom of Great Britain and Ireland in January 1919 (not to be confused with the proclamation of the Irish Republic that was a different Irish Republic or the Republic of Ireland Act 1948).
 The Republic claimed jurisdiction over the whole island of Ireland, but by 1920 its functional control was limited to only 21 of Ireland's 32 counties, and British state forces maintained presence across much of the north-east, as well as Cork, Dublin and other major towns.
The Irish Free State Constitution Act 1922 (Session 2) was an Act of the Parliament of the United Kingdom, passed in 1922 to enact in UK law the Constitution of the Irish Free State, and to formally ratify the 1921 Anglo-Irish Treaty of 6 December 1921.
The Anglo-Irish Treaty (Irish: "An Conradh Angla-Éireannach" ), commonly known as The Treaty and officially the Articles of Agreement for a Treaty Between Great Britain and Ireland, was an agreement between the government of the United Kingdom of Great Britain and Ireland and representatives of the Irish Republic that concluded the Irish War of Independence.
 It provided for the establishment of the Irish Free State within a year as a self-governing dominion within the 'community of nations known as the British Empire', a status 'the same as that of the Dominion of Canada'.
 It also provided Northern Ireland, which had been created by the Government of Ireland Act 1920, an option to opt out of the Irish Free State, which it exercised.
The Irish Republican Army was a guerrilla army that fought the Irish War of Independence against Britain from 1919–1921.
 It saw itself as the legitimate army of the Irish Republic declared in 1919.
 The Anglo-Irish Treaty, which ended this conflict, was a compromise which abolished the Irish Republic, but created the self-governing Irish Free State, within the British Empire.
 The IRA was deeply split over whether to accept the Treaty.
 Some accepted, whereas some rejected not only the Treaty but also the civilian authorities who had accepted it.
 This attitude eventually led to the outbreak of the Irish Civil War in late June 1922 between pro- and anti-Treaty factions.
