History

Swainby was first recorded in Domesday Book of 1086, in the form Suanebi. The name means 'farm of the young men,' from the Old Norse sveinn. At the time of the Domesday Survey the manor was held by Count Alan of Brittany and the tenant was Ribald, Lord of Middleham. In about 1188 Ribald's descendant Helewise granted land at Swainby for a new monastery, but in 1214-16 Helewise's son moved the monks to refound the abbey at Coverham. Both the remaining traces of Swainby Abbey and the remains of the deserted village are now listed as a scheduled monument.

Allerthorpe is located in the north of the civil parish. It now comprises only the manor house, Allerthorpe Hall, built in 1608 and now a Grade I listed building. Allerthorpe was also first recorded in Domesday Book, in the form erleuestorp. The name is Old Norse and means "village of a man named Herlef".

The parish was historically a township in the parish of Pickhill in the wapentake of Hallikeld in the North Riding of Yorkshire. It became a separate civil parish in 1866. It was transferred to the new county of North Yorkshire in 1974. From 1974 to 2023 the parish was part of the district of Hambleton. It is now administered by the unitary North Yorkshire Council. It shares a grouped parish council with the civil parishes of Burneston and Theakston.
