Armagh was a county constituency of the Parliament of Northern Ireland from 1921 to 1929. It returned four MPs, using proportional representation by means of the single transferable vote.
Armagh was created by the Government of Ireland Act 1920 and consisted of the entirety of County Armagh. The House of Commons (Method of Voting and Redistribution of Seats) Act (Northern Ireland) 1929 divided the constituency into four constituencies elected under first past the post: Central, Mid, North and South Armagh constituencies.[1]
In May 1921, Dáil Éireann, the parliament of the self-declared Irish Republic run by Sinn Féin, passed a resolution declaring that elections to the House of Commons of Northern Ireland and the House of Commons of Southern Ireland would be used as the election for the Second Dáil.[2] All those elected were on the roll of the Second Dáil, but Michael Collins, who was also elected for Cork Mid, North, South, South East and West, was the only MP elected for Armagh to sit as a TD in Dáil Éireann.[3]
Armagh had a slight Unionist majority, but this was fairly evenly balanced with a Nationalist minority. In both general elections, two Unionists were elected, alongside one Nationalist and one Republican.
