Crompton was recorded in 1212 as being one of the five parts of the thegnage estate of Kaskenmoor, which was held on behalf of King John by Roger de Montbegon and William de Nevill. The other parts of this estate were Glodwick, Sholver, Oldham, and Werneth, names and places still familiar today. Crompton would later form a township within the ancient ecclesiastical parish of Prestwich-cum-Oldham, in the hundred of Salford. Throughout the Middle Ages, local men acted as jurors and constables for the purposes of upholding law and order in the township.
