In 1216 the Abbot of Croxton Abbey was summoned to Newark Castle where King John lay dying.

His son, King Henry III, later made a number of donations to the abbey in memory of his father.

This, coupled with the devastation of the abbey's possessions in the North of England by Scottish raiders, led to the house being a staggering £2,000 in debt by 1348.

Further misfortune was brought by the Black Death which killed all of the abbey's senior canons, except for the abbot and prior.

[1] There were also gains during the 14th century, with the acquisition of the manor of Croxton Kerrial around 1335, and the advowson of the church of Finedon, Northamptonshire, in 1346.

Henry Manners, 2nd Earl of Rutland preserved "the monumental remains of his ancestors, by transferring them chiefly to Bottesford", from Croxton and Belvoir Priory.
