The
Constitution of the Irish Free State 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 and was proclaimed by
Royal Proclamation on 6 December 1922 in accordance with Article 83 of the Constitution and came into operation on the issue of that Proclamation. On the previous day the
Irish Free State Constitution Act 1922 of the British Parliament received the Royal Assent and gave effect to the Constitution under British law. In 1937 it was replaced by the modern
Constitution of Ireland following a
referendum.
