Irish heads of government since 1919

(Redirected from List of prime ministers of Ireland)

Ireland

The head of government, or prime minister, of Ireland is known as the Taoiseach and heads a cabinet called the Government. However, since 1919, heads of government in the Irish state have borne a number of titles. Under the short-lived Irish Republic of 1919–22 the head of government was known first as the President of Dáil Éireann and later as the President of the Republic. Under the Irish Free State of 1922–37 the head of government was the President of the Executive Council. There also briefly existed, immediately before the creation of the Irish Free State, an interim office of Chairman of the Provisional Government. For a brief period in 1921 the offices of President of the Republic and Chairman of the Provisional Government existed simultaneously.

Northern Ireland

The most recent devolved cabinet in Northern Ireland is the Northern Ireland Executive, established under the Good Friday Agreement. The Executive has been in operation, intermittently, since 1999; but had existed continuously since 2007, but after elections following a government collapsed on 16 January 2017, no Executive was formed until January 2020, when the parties came to an agreement and an Executive was subsequently established. Since 1921, there have been three different prime ministerial offices in Northern Ireland. The most recent structure, the Office of the First Minister and deputy First Minister, represents a diarchy. As such, there is no longer a singular executive office, but rather a dual office.

Notes

The President of Dáil Éireann, also known as the Príomh Aire, was upgraded to a head of state-level President of the Irish Republic in August 1921.
^ From January to August 1922 there were two administrations operating in parallel, the Ministry of the self-declared independent Irish Republic and the Provisional Government accepted by the United Kingdom, and each cabinet had an overlapping membership. De Valera had filled both posts, but after his resignation there were two heads of government, Arthur Griffith, as President of the Republic, and Michael Collins as Chairman of the Provisional Government of Southern Ireland. This anomalous situation came about because the British Government would only recognise the parliament that it had established through the Government of Ireland Act, so Sinn Féin participated in the charade to move matters along. To add to the confusion, Collins was Griffith's Minister of Finance, while Griffith was Collins's Minister for Foreign Affairs. The dual leadership came to an end when W. T. Cosgrave assumed both offices on the deaths of Griffith, on 12 August 1922, and Collins, on 22 August, and merged the two parallel administrations.
Successor of the Sinn Féin Anti-Treaty faction.
Successor of Cumann na nGaedheal and two more parties.
Created the Viscount Craigavon in 1927.
Created the Viscount Brookeborough in 1952.
