Dublin Corporation (Irish: Bardas Bhaile Átha Cliath), known by generations of Dubliners simply as The Corpo, is the former name of the city government and its administrative organisation in Dublin since the time of Henry II. Significantly re-structured in 1660-1661, even more significantly in 1840, it was modernised on 1 January 2002, as part of a general reform of local government in Ireland, and since then is known as Dublin City Council. This article deals with the history of municipal government in Dublin up to 31 December 2001.
