The Fourth Home Rule Bill was an all-Ireland law-making authority called The Council of Ireland, which had how many members?
Council of Ireland The Council of Ireland (Irish: "Comhairle na hÉireann" ) was a statutory body established under the Government of Ireland Act 1920 as an all-Ireland law-making authority with limited jurisdiction, initially over both Northern Ireland and Southern Ireland, and later solely over Northern Ireland. It had 41 members: 13 members of each of the Houses of Commons of Southern Ireland and of Northern Ireland; 7 members of each of the Senates of Southern Ireland and of Northern Ireland; and a President chosen by the Lord-Lieutenant of Ireland. It was abolished in 1925.
Oath of Allegiance (Ireland) The Irish Oath of Allegiance (Irish: "Mionn Dílse" ) 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.
