Antrim County Council

Antrim County Council was formed under orders issued under the Local Government (Ireland) Act 1898 which came into effect on 1 April 1899.^[1][2][3] It was the council for the administrative county of Antrim, which included the existing judicial county of Antrim, except the part in the city of Belfast; the existing judicial county of the town of Carrickfergus; and the part of the existing judicial county of Down containing the town of Lisburn.^[4]

The Local Government (Ireland) Act 1919 introduced proportional representation by means of the single transferable vote (PR-STV) for the 1920 Antrim County Council election.^[5] PR-STV was abolished in Northern Ireland under the Local Government Act 1922, with a reversion to first-past-the-post for the 1924 Northern Ireland local elections, the first local elections held in the new jurisdiction.^[6][7]

It was originally based at the Crumlin Road Courthouse^[8] but moved to County Hall in Ballymena in 1970.^[9] It was abolished on 1 October 1973 under the Local Government Act (Northern Ireland) 1972.^[10]
