In 1919 The First Dáil elected its first Áireacht or Ministry. Since then Irish governments have been formed under three constitutions, the Dáil Constitution (1919-1922), the Irish Free State Constitution Act, 1922 and Bunreacht na hÉireann (1937-present).
The method of government formation differed in each.
- In the Dáil Constitution, the head of government, the Príomh Áire/President of Dáil Éireann/President of the Republic was elected by the Dáil. He then formed a ministry.
- In the Irish Free State constitution, the Governor-General of the Irish Free State appointed the head of government, the President of the Executive Council on the nomination of Dáil Éireann (the Chamber of Deputies).
- Under Bunreacht na Éireann, the President of Ireland appoints the head of government, the Taoiseach, on the nomination of Dáil Éireann (the House of Representatives).
