Cavan is a former parliamentary constituency represented in Dáil Éireann, the house of representatives of the Oireachtas, from 1921 to 1977. The method of election was proportional representation by means of the single transferable vote (PR-STV).
History and boundaries The constituency was created in 1921 under the Government of Ireland Act 1920 as a 3-seat constituency for the Southern Ireland House of Commons and a single-seat constituency for the United Kingdom House of Commons at Westminster, combining the former Westminster constituencies of East Cavan and West Cavan. At the 1921 election for the Southern Ireland House of Commons, the three seats were won uncontested by Sinn Féin, who treated it as part of the election to the Second Dáil. It was never used as a Westminster constituency; under 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 Cavan 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.
The constituency was recreated under the Electoral Act 1923, the first electoral act of the new state. At the 1977 general election, the Cavan and Monaghan constituencies were abolished and succeeded by the new 5-seat Cavan–Monaghan constituency.
