The Percies were an important family in northern England whose ancestor, William de Percy, received lands in Yorkshire and elsewhere from William I. Henry Percy served under Edward III and was created earl of Northumberland and Marshal of England in 1377. Although he originally supported Richard II, he turned against him because of the king's increased violence and excesses and supported the invasion of Henry IV in 1399. For this he received further honors including the kingdom of Man. Percy and his son, Hotspur, soon turned againsts Henry IV and plotted with Edmund Mortimer and Owain Glyn Dwr to dethrone the king and share England and Wales between them. He was declared a traitor and deprived of his lands. Earl of NothumberlandHenryPercy was born in 1342. He died on 20 February 1408; Henry was killed in battle at Bramham Moor.
