Oath of Allegiance (Ireland)

The Irish Oath of Allegiance was a controversial provision in the Anglo-Irish Treaty of 1921, which Irish TDs (members of the Lower House of the Irish Parliament) and Senators were required to swear before taking their seats in Dáil Éireann (Chamber of Deputies) and Seanad Éireann (Irish Senate) before the 'Constitution (Removal of Oath) Act, 1933' was passed on 3 May 1933. The controversy surrounding the Oath was one of the principal issues that led to the Irish Civil War of 1922–23 between supporters and opponents of the Treaty.

Ironically, in view of the opposition expressed to the oath by anti-treaties, it was in fact largely the work of Michael Collins, based in its open lines on a draft oath suggested by the President of the Republic, Éamon de Valera, and also on the oath of the Irish Republican Brotherhood. In fact, Collins cleared the oath with the IRB before proposing it during the treaty negotiations. By the standards of the oaths of allegiance to be found in other British Commonwealth Dominions, it was quite mild, with no direct personal Oath to the monarch, only an indirect oath of fidelity by virtue of the King's role in the treaty settlement as "King in Ireland", a figurehead position. The public perception among those who were hostile to the treaty was that it was an offensive oath due to its inclusion of the British monarch. They claimed:
