Henry experienced a more inconsistent relationship with King Richard II than his father had. First cousins and childhood playmates, they were admitted together as knights of the Order of the Garter in 1377, but Henry participated in the Lords Appellants' rebellion against the king in 1387. After regaining power, Richard did not punish Henry, although he did execute or exile many of the other rebellious barons. In fact, Richard elevated Henry from Earl of Derby to Duke of Hereford.
