A county council is the elected administrative body governing an area known as a county. This term has slightly different meanings in different countries.
County councils were formed in the late 19th century. In the various constituent countries of the United Kingdom councils had different powers and different memberships. Following local government reforms in the 1970s, county councils no longer exist in Scotland or Northern Ireland. In England they generally form the top level in a two-tier system of administration; in Wales they are unitary authorities.
In England county councils were introduced in 1889, and reformed in 1974. Since the mid-1990s a series of local government reorganisations has reduced the number of county councils as unitary authorities have been established in a number of areas. County councils are very large employers with a great variety of functions including education (schools and youth services), social services, highways, fire and rescue services, libraries, waste disposal, consumer services and town and country planning. Until the 1990s they also ran colleges of further education and the careers services. That decade also saw the privatisation of some traditional services, such as highway maintenance, cleaning and school meals.
County councils were created by the Local Government Act 1888, largely taking over the administrative functions of the unelected county courts of quarter sessions. County councils consisted of councillors, directly elected by the electorate; and county aldermen, chosen by the council itself. There was one county alderman for every three councillors (one for every six in the London County Council). The first elections to the councils were held at various dates in January 1889, and they served as "provisional" or shadow councils until 1 April, when they came into their powers. Elections of all councillors and half of the aldermen took place every three years thereafter. The areas over which the councils had authority were designated as administrative counties. The writ of the county councils did not extend everywhere: large towns and some historic counties corporate were constituted county boroughs by the same act. County borough councils were independent of the council for the county in which they were geographically situated, and exercised the functions of both county and district councils. The new system was a major modernisation, which reflected the increasing range of functions carried out by local government in late Victorian Britain. A major accretion of powers took place when education was added to county council responsibilities in 1902. County councils were responsible for more strategic services in a region, with (from 1894) smaller urban district councils and rural district councils responsible for other activities. The Local Government Act 1929 considerably increased the powers of county councils, who took charge of highways in rural districts.
