The State Management Scheme was the nationalisation of the brewing, distribution and sale of liquor in three dustricts of the United Kingdom from 1916 until 1973.The main focus of the scheme was Carlisle and the surrounding district close to the armament factories at Gretna, founded in 1916 to supply explosives and shells to the British Army in the First World War. However, there were three schemes in total: Carlisle and Gretna, Cromarty Firth, and Enfield. In 1921 Carlisle and Gretna was split into two separate areas. Carlisle was the larger part and supplied some beer to Gretna. In 1922 the Enfield scheme ended and its public houses were sold back to private enterprise.
