Humphrey de Bohun, 3rd Earl of Hereford, English politician, Lord High Constable of England (b. 1249)
Humphrey (VI) de Bohun (c. 1249 – 31 December 1298), 3rd Earl of Hereford and 2nd Earl of Essex, was an English nobleman known primarily for his opposition to King Edward I over the Confirmatio Cartarum. He was also an active participant in the Welsh Wars and maintained for several years a private feud with the earl of Gloucester. His father, Humphrey (V) de Bohun, fought on the side of the rebellious barons in the Barons' War. When Humphrey (V) predeceased his father, Humphrey (VI) became heir to his grandfather, Humphrey (IV). At Humphrey (IV)'s death in 1275, Humphrey (VI) inherited the earldoms of Hereford and Essex. He also inherited major possessions in the Welsh Marches from his mother, Eleanor de Braose.
Bohun spent most of his early career reconquering Marcher lands captured by Llywelyn ap Gruffudd during the Welsh war in England. This was finally accomplished through Edward I's war in Wales in 1277. Hereford also fought in Wales in 1282–83 and 1294–95. At the same time he also had private feuds with other Marcher lords, and his conflict with Gilbert de Clare, Earl of Gloucester, eventually ended with the personal intervention of King Edward himself. Hereford's final years were marked by the opposition he and Roger Bigod, Earl of Norfolk, mounted against the military and fiscal policy of Edward I. The conflict escalated to a point where civil war threatened, but was resolved when the war effort turned towards Scotland. The king signed the Confirmatio Cartarum – a confirmation of Magna Carta – and Bohun and Bigod agreed to serve on the Falkirk Campaign. Bohun died in 1298, and was succeeded by his son, Humphrey de Bohun, 4th Earl of Hereford.
