Metropolitan Borough of Sefton

The Metropolitan Borough of Sefton is a metropolitan borough of Merseyside, England. It was formed on 1 April 1974, by the amalgamation of the county boroughs of Bootle and Southport, the municipal borough of Crosby, the urban districts of Formby and Litherland, and part of West Lancashire Rural District. It consists of a coastal strip of land on the Irish Sea which extends from Southport in the north to Bootle in the south, and an inland part to Maghull in the south-east, bounded by the city of Liverpool to the south, the Metropolitan Borough of Knowsley to the south-east, and West Lancashire to the east.

It is named after Sefton, near Maghull. When the borough was created, a name was sought that would not unduly identify the borough with any of its constituent parts, particularly the former county boroughs of Bootle and Southport. The area had strong links with both the Earl of Sefton and the Earl of Derby, resident of Knowsley Hall, and the adjacent borough was subsequently named Knowsley. A Sefton Rural District covering some of the villages in the district existed from 1894 to 1932.
