Tayside was one of the 12 regions into which Scotland was divided from 1975 to 1996. During that period the Tayside Regional Council provided a range of local government services across a large part of Scotland extending from the North Sea to the highlands.
Tayside was formed in 1975 by bringing together the traditional county areas of Kinross-shire, Angus and most of Perthshire. A large part of the west side of the traditional county of Perthshire was transferred to Stirling District in Central Region. This extended from Killin in the north-east to Tyndrum in the north-west, and south past Crianlarich to take in Callander, Aberfoyle, Doune and Dunblane.
Tayside was bordered by the regions of Fife, Central, Strathclyde and Highland. As a region, Tayside was the upper of two tiers of local government. The lower tier comprised three district councils: Perth & Kinross, Angus and the City of Dundee. Perth & Kinross was formed by the merger of Kinross-shire with those parts of Perthshire not lost to Stirling. The new district of City of Dundee was carved out of the south-west corner of Angus.
In 1996, a further major reorganisation swept away Scotland's regions and districts and replaced them with 32 unitary councils. Tayside's three district council areas were all translated into unitary council areas: and the area is now divided among the unitary councils of Perth & Kinross, Angus and City of Dundee.
Although Tayside disappeared in 1996 as a local government unit, its name and coverage live on in bodies such as NHS Tayside.
