Henry Percy was originally a follower of Edward III of England , for whom he held high offices in the administration of northern England. At a young age he was made Warden of the Marches towards Scotland in 1362, with the authority to negotiate with the Scottish government. In February 1367 he was entrusted with the supervision of all castles and fortified places in the Scottish marches. He went on to support King Richard II and was created an Earl and briefly given the title of Marshal of England . After Richard elevated his rival Ralph Neville to the position of Earl of Westmorland in 1397, Percy supported the rebellion of Henry Bolingbroke , who became King as Henry IV.
On King Henry IV's coronation he was appointed Constable of England and granted the lordship of the Isle of Man . Percy and his son, Henry Percy , known as "Hotspur", were given the task of subduing the rebellion of Owain Glyndwr , but their attempts to make peace with the Welsh rebels did not meet with the king's approval.
In 1403 the Percys turned against Henry IV in favour of Edmund Mortimer, 5th Earl of March , and then conspired with Owain Glynd against King Henry. The Tripartite Indenture was signed by all three parties, which divided England up between them. Glynd was to be given Wales , and a substantial part of the west of England , Northumberland was to have received the north of England, as well as Northamptonshire , Norfolk , Warwickshire , and Leicestershire . The Mortimers were to have received the rest of southern England, below the river Trent.[2]
The Percy rebellion failed at the Battle of Shrewsbury , where Hotspur was killed. Since the earl did not directly participate in the rebellion, he was not convicted of treason. However, he lost his office as Constable. In 1405 Percy supported Richard le Scrope , Archbishop of York , in another rebellion, after which Percy fled to Scotland, and his estates were confiscated by the king.
In 1408 Percy invaded England in rebellion once more and was killed at the Battle of Bramham Moor . Percy's severed head was subsequently put on display at London Bridge.

Alnwick Castle, the traditional home of the Percy family, was featured in the Harry Potter movies as the location of Hogwarts
