The Wikipedia article of the day for August 17, 2021 is Murder of William de Cantilupe.
William de Cantilupe was killed by multiple stab wounds in Scotton, Lincolnshire, in March 1375. The de Cantilupes were a wealthy English family and had a history of service to the crown. They were major landholders in the Midlands, with estates in Greasley, Ilkeston, and Withcall. William de Cantilupe’s ancestors included royal councillors and, distantly, Saint Thomas de Cantilupe. Among the suspects in the murder were his wife Maud and the sheriff Thomas Kydale. Maud may have had an affair with Kydale during her husband’s frequent absences on service during the war in France. Fifteen members of the household were also accused. De Cantilupe’s murder was the first to come within the purview of the Treason Act 1351, a statute which declared the murder of a man by his wife or servants to be petty treason. Maud was tried and acquitted. She then married Kydale. Two members of the household staff were convicted and executed. Others who were indicted did not appear for trial and were outlawed. One of the outlaws, de Cantilupe’s steward, John Tailour of Barneby, was pardoned by Richard II.
