Thomas Percy, 1st Baron Egremont (29 November 1422 – 10 July 1460) was a scion of a leading noble family from northern England during the fifteenth century.
Described by one historian as "quarrelsome, violent and contemptuous of all authority",[1] Egremont was involved in numerous riots and disturbances in the northern localities, and became a leading figure in the internecine Percy–Neville feud.
[1] Following the skirmish with the men of Beverley, he was subsequently imprisoned at York Castle- the direct result, it has been suggested of the Archbishop manipulating the jury and County Sheriff, whilst getting his own tenants released instead.
[2] Conflict in the north was not only over local rivalries; English relations with Scotland periodically descended into warfare throughout the Middle Ages, and the mid-fifteenth century was no exception.
[8] It is not certain exactly when the bad blood between the two families begun; A. J. Pollard has pointed out that they were cooperating together over parliamentary elections in 1449, and as late as 1453; the former husting was attended by Sir Thomas Percy shortly before his elevation to the peerage.
