It was created for the 1985 local elections, replacing Castlereagh Area A which had existed since 1973, and originally contained seven wards (Beechill, Carryduff, Four Winds, Knockbracken, Minnowburn, Moneyreagh and Newtownbreda). For the 1993 local elections, it was reduced to five wards, with Carryduff splitting into East and West and gaining Cairnshill but losing Beechill, Minnowburn and Newtownbreda to the new Castlereagh West DEA. For the 2014 local elections, it was increased to seven wards, regaining the areas which had previously gone to Castlereagh West.
