Sir Henry Percy, also called Harry Hotspur (1364 ? - 1403) was the eldest son of the 1st Earl of Northumberland and 4th Lord Percy of Alnwick. His nickname is suggestive of his impulsive nature.
Harry acquired a great reputation as a warrior, fighting against the Scots and the French. He fought against the Scots at the Battle of Otterburn in 1388.
With his father he helped depose Richard II of England, but later with his uncle Thomas Percy, Earl of Worcester he led a rebellion against King Henry IV in 1403, forming an alliance with another rebel, Owen Glendower. Before they could join forces, Hotspur was defeated and killed at the Battle of Shrewsbury. He is a major character in Shakespeare's Henry IV, Part 1.
