Thomas Percy, 1st Baron Egremont

Thomas Percy, 1st Baron Egremont 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", Egremont was involved in numerous riots and disturbances in the northern localities, and became a leading figure in the internecine Percy–Neville feud. When the Wars of the Roses began mid-decade, Egremont fought for the king on the Lancastrian side, being killed five years later at the Battle of Northampton. ^{Thomas Percy, 1st Baron Egremont, English Baron (d. 1460)}
