Henry IV of England
King of England and Lord of Ireland.
He was the tenth King of England of the House of Plantagenet and also asserted his grandfather's claim to the title King of France. He was born at Bolingbroke Castle in Lincolnshire, hence his other name, Henry Bolingbroke /ˈbɒlɪŋbrʊk/. His father, John of Gaunt, was the third son of Edward III, and enjoyed a position of considerable influence during much of the reign of Henry's cousin Richard II, whom Henry eventually deposed. Henry's mother was Blanche, heiress to the considerable Lancaster estates, and thus he became the first King of England from the Lancaster branch of the Plantagenets
