As a result of the 2009 structural changes to local government in England, the former Wiltshire County Council and the four districts within its geographical area were replaced by the new Wiltshire Council, which is a unitary authority covering the same area, with elections continuing to be held every four years, beginning in June 2009. Previously, Wiltshire County Council had been elected between 1889 and 2005, initially every three years, later every four years.
The county council was established in 1889 as the principal local authority for the historic county of Wiltshire. It continued as such until April 1997, when the borough of Swindon became a unitary authority, taking almost a third of the population out of the area then falling under Wiltshire County Council. From 2009, it became Wiltshire Council.
