Oireachtas (Irish Free State) in the context of "Parliament of Ireland"

The Irish Free State (6 December 1922 – 29 December 1937), also known by its Irish name Saorstát Éireann (English: /ˌsɛərstɑːt ˈɛərən/ SAIR-staht AIR-ən, Irish: [ˈsˠiːɾˠsˠt̪ˠaːt̪ˠ ˈeːɾʲən̪ˠ]), was a state established in December 1922 under the Anglo-Irish Treaty of December 1921. The treaty ended the three-year Irish War of Independence between the forces of the Irish Republic—the Irish Republican Army (IRA)—and British Crown forces.

The Free State was established as a dominion of the British Empire. It comprised 26 of the 32 counties of Ireland. Northern Ireland, which was made up of the remaining six counties, exercised its right under the Treaty to opt out of the new state. The Irish Free State government consisted of the governor-general—the viceregal representative of the King—and the Executive Council (cabinet), which replaced both the revolutionary Dáil Government and the Provisional Government set up under the Treaty. W. T. Cosgrave, who had led both of these administrations since August 1922, became the first president of the Executive Council (prime minister). The Oireachtas or legislature consisted of Dáil Éireann (the lower house) and Seanad Éireann (the upper house), also known as the Senate. Members of the Dáil were required to take an Oath of Allegiance to the Constitution of the Free State and to declare fidelity to the King. The oath was a key issue for opponents of the Treaty, who refused to take it and therefore did not take their seats. Pro-Treaty members, who formed Cumann na nGaedheal in 1923, held an effective majority in the Dáil from 1922 to 1927 and thereafter ruled as a minority government until 1932.

The President of the Executive Council of the Irish Free State (Irish: Uachtarán ar Ard-Chomhairle Shaorstát Éireann) was the head of government or prime minister of the Irish Free State which existed from 1922 to 1937. He was the chairman of the Executive Council of the Irish Free State, the Free State's cabinet. The President was appointed by the Governor-General, upon the nomination of Dáil Éireann (the lower house of the Oireachtas of parliament) and had to enjoy the confidence of the Dáil to remain in office. The office was succeeded by that of Taoiseach, though subsequent Taoisigh are numbered from the first President of the Executive Council.

Dáil Éireann (Irish: [ˌd̪ˠaːlʲ ˈeːɾʲən̪ˠ]) served as the directly elected lower house of the Oireachtas of the Irish Free State from 1922 to 1937. The Free State constitution described the role of the house as that of a "Chamber of Deputies". Until 1936 the Free State Oireachtas also included an upper house known as the Seanad. Like its modern successor, the Free State Dáil was, in any case, the dominant component of the legislature; it effectively had authority to enact almost any law it chose, and to appoint and dismiss the President of the Executive Council (prime minister). The Free State Dáil ceased to be with the creation of the modern 'Dáil Éireann' under the terms of the 1937 Constitution of Ireland. Both the Dáil and Seanad sat in Leinster House.

Seanad Éireann (Irish pronunciation: [ˈʃan̪ˠəd̪ˠ ˈeːɾʲən̪ˠ]; Senate of Ireland) was the upper house of the Oireachtas (parliament) of the Irish Free State from 1922 to 1936. It has also been known simply as the Senate, First Seanad, Free State Senate or Free State Seanad. The Seanad was established under the 1922 Constitution of the Irish Free State. A number of constitutional amendments were made to change the manner of its election and its powers. It was eventually abolished in 1936 when it attempted to obstruct constitutional reforms favoured by the government. It sat, like its modern successor, in Leinster House.

Dáil Éireann (English: Assembly of Ireland), also called the Revolutionary Dáil, was the revolutionary, unicameral parliament of the Irish Republic from 1919 to 1922. The Dáil was first formed on 21 January 1919 in Dublin by 69 Sinn Féin MPs elected in the 1918 United Kingdom general election, who had won 73 seats of the 105 seats in Ireland, with four party candidates (Arthur Griffith, Éamon de Valera, Eoin MacNeill and Liam Mellows) elected for two constituencies. Their manifesto refused to recognise the British parliament at Westminster and instead established an independent legislature in Dublin. The convention of the First Dáil coincided with the beginning of the War of Independence.

The First Dáil was replaced by the Second Dáil in 1921. Both of these Dála existed under the proclaimed Irish Republic; it was the Second Dáil which narrowly ratified the Anglo-Irish Treaty. The status of the Third Dáil of 1922–1923 was different as it was also recognised by the British. It was elected under the terms of the 1921 Anglo-Irish Treaty as a provisional parliament to pave the way for the creation of an independent Irish state. With the establishment of the Irish Free State in 1922, a new parliament called the Oireachtas was established, of which Dáil Éireann became the lower house.

Fianna Fáil (/ˌfiː(ə)nə ˈfɔɪl, -ˈfɔːl/ ; Irish: [ˌfʲiən̪ˠə ˈfˠaːlʲ]; meaning "Soldiers of Destiny" or "Warriors of Fál"), officially Fianna Fáil – The Republican Party (Irish: Fianna Fáil – An Páirtí Poblachtánach), is a centre to centre-right political party in Ireland.

Fianna Fáil was founded as a republican party in 1926 by Éamon de Valera and his supporters after they split from Sinn Féin in order to take seats in the Oireachtas, which Sinn Féin refused to recognise. Since 1927, Fianna Fáil has been one of Ireland's two major parties, along with Fine Gael since 1933; both are seen as centre-right parties, to the right of the Labour Party and Sinn Féin. The party dominated Irish political life for most of the 20th century, and, since its foundation, either it or Fine Gael has led every government. Between 1932 and 2011, it was the largest party in Dáil Éireann, but latterly with a decline in its vote share; from 1989 onwards, its periods of government were in coalition with parties of either the left or the right.
