Henry Bolingbroke, later known as King Henry IV of England, was born in 1367. He was the son of John of Gaunt, the Duke of Lancaster, and played a significant role in the political landscape of England during the late 14th century. Bolingbroke initially served as a loyal supporter of King Richard II but later became his rival. In 1399, Bolingbroke returned from exile to claim his inheritance and ultimately deposed Richard II, becoming king himself. His reign marked the beginning of the Lancastrian dynasty, which would influence English history for many years. Henry IV faced numerous challenges, including rebellions and conflicts with the Welsh and Scots.
