Dublin Clontarf (UK Parliament constituency)

Clontarf, a division of the parliamentary borough of Dublin, was a parliamentary constituency which returned one Member of Parliament (MP) to the House of Commons of the United Kingdom from 1918 until 1922. From 1918 to 1921, it was also used a constituency for Dáil Éireann.

It predominantly comprised the area of Clontarf which had been brought into the jurisdiction of the city in 1900, since the last time of a revision of constituencies. It was defined as:

History
Under the Redistribution of Seats Act 1885, the parliamentary borough of Dublin had been divided into four divisions: College Green, Dublin Harbour, St Stephen's Green and St Patrick's. Under the Redistribution of Seats (Ireland) Act 1918, the city was allocated three additional seats: Dublin Clontarf, St James's and St Michan's.

At the 1918 general election, Sinn Féin issued an election manifesto in which it called for a "establishment of a constituent assembly comprising persons chosen by Irish constituencies". After the election, Sinn Féin invited all those elected for Irish constistuencies to sit as members of Dáil Éireann, termed Teachta Dála (or TD, known in English as a Deputy). In practice, only those elected for Sinn Féin attended. This included Richard Mulcahy, elected for Clontarf.

Under the Government of Ireland Act 1920, the area was combined with the St James's and St Michan's Divisions to form Dublin North-West, a 4-seat constituency for the Southern Ireland House of Commons and a single-seat constituency at Westminster. At the 1921 election for the Southern Ireland House of Commons, the four seats were won uncontested by Sinn Féin, who treated it as part of the election to the Second Dáil. Richard Mulcahy was one of the four TDs for Dublin North-West.

Under s. 1(4) of the Irish Free State (Agreement) Act 1922, no writ was to be issued "for a constituency in Ireland other than a constituency in Northern Ireland". Therefore, no vote was held in Dublin North-West at the 1922 United Kingdom general election on 15 November 1922, shortly before the Irish Free State left the United Kingdom on 6 December 1922.
