The current Constitution of Ireland came into effect on 29 December 1937, repealing and replacing the Constitution of the Irish Free State, having been approved in a national plebiscite on 1 July 1937 with the support of 56.5% of voters in the then Irish Free State. The Constitution was closely associated with Éamon de Valera, the President of the Executive Council of the Irish Free State at the time of its approval (and who assumed the position of Taoiseach on its adoption).
