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 Cartaruma confirmation of Magna Cartaand 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. Family background and inheritance Humphrey (VI) de Bohun was part of a line of Anglo-Norman aristocrats going back to the Norman Conquest, most of whom carried the same name. His grandfather was Humphrey (IV) de Bohun, who had been part of the baronial opposition of Simon de Montfort, but later gone over to the royal side. He was taken prisoner at the Battle of Lewes in May 1264, but was restored to favour after the royalist victory at the Battle of Evesham the next year. Humphrey (IV)'s son, Humphrey (V) de Bohun, remained loyal to the baronial side throughout the Barons' War, and was captured at Evesham on 4 August 1265. In October of that year, Humphrey (V) died in captivity
