Strathclyde, former administrative region, western Scotland. In 1996 Strathclyde was dissolved and divided into 12 new unitary authorities: Argyll and Bute, East Dunbartonshire, West Dunbartonshire, South Lanarkshire, North Lanarkshire, East Ayrshire, North Ayrshire, East Renfrewshire, City of Glasgow, Inverclyde, South Ayrshire, and Renfrewshire.
Strathclyde was originally created in 1975 by the merger of the former counties of Ayrshire, Buteshire, Dunbartonshire, Lanarkshire, and Renfrewshire, with most of Argyllshire and a small part of Stirlingshire. The former region extended from the Grampian Mountains in the north to lowland farming areas in the south. The heavily industrialized central area centers on Glasgow; nearby, to the east, are the coal mining districts. Along the former region's western coast and the southern islands of the Inner Hebrides are numerous resort towns.
