Soke of Peterborough

The Soke of Peterborough is a historic area of England associated with the City and Diocese of Peterborough, but considered part of Northamptonshire. The Soke was also described as the Liberty of Peterborough, or Nassaburgh hundred, and comprised, besides Peterborough, about thirty parishes.

The area forms much of the present City of Peterborough unitary authority area in the post-1974 ceremonial county of Cambridgeshire. The Church of England dioceses of Peterborough and Ely still, however, follow the boundary of the Soke, with only the part of the city that is north of the River Nene lying within the Diocese of Peterborough, while Thorney and urban areas south of the Nene, including Stanground and Fletton, are in the Diocese of Ely.

The term soke refers to a general legal term in medieval England referring to various concepts, including a jurisdiction of land or rights to hold a court or receive fines.
