Dublin Corporation (Irish: Bardas Bhaile Átha Cliath), known by generations of Dubliners simply as The Corpo, is the former name given to the city government and its administrative organisation in Dublin between 1661 and 1 January 2002. It is now known as Dublin City Council.
The long form of its name was The Lord Mayor, Aldermen and Burgesses of the City of Dublin.
Two chamber Corporation
Dublin Corporation first came into being under the Anglo-Normans in Dublin in the late 13th century. For centuries it was a two chamber body, made up of an upper house of Aldermen and a lower house, known as the Sheriffs and Commons, consisting the 48 Sheriff's representatives and 96 representatives of guilds. The upper house was presided over by a mayor, who was elected from and by the Aldermen.
19th century reform
The modern Dublin Corporation was restructured by late 19th century and 20th century legislation, particularly, the Municipal Corporations (Ireland) Act 1840, with the elected body reduced to a single chamber Dublin City Council, presided over by the Lord Mayor of Dublin, an office first instituted but not filled by King Charles I and reconstituted following the Restoration of the Crown by King Charles II. A later monarch, Queen Victoria, refused to visit Ireland for a number of years, partly in protest at Dublin Corporation's decision not to congratulate her son, Prince Albert Edward, The Prince of Wales, on both his marriage to Princess Alexandra of Denmark and on the birth of the royal couple's oldest son, Prince Albert Victor.
21st century change of name
On 1 January 2002, following a major reform of local government which also abolished the 300 year old title of Alderman in the Republic of Ireland and 700 year old title of 'town clerk' in Dublin, the name of Dublin Corporation was abolished, with the 19th century name Dublin City Council, that previously had been used simply to refer to the assembly of elected councillors, being given for the entire administration.
