Henry of Monmouth, the eldest son of Henry IV, became heir apparent and Prince of Wales after his father seized the throne in 1399. During the reign of his father, the young Prince Henry gained military experience fighting the Welsh during the revolt of Owain Glyndŵr, and against the powerful Percy family of Northumberland. He played a central part at the Battle of Shrewsbury despite being just sixteen years of age. As he entered adulthood, Henry played an increasingly central role in England's government due to the declining health of his father, but disagreements between Henry and his father led to political conflict between the two. After his father's death in March 1413, Henry ascended to the throne of England and assumed complete control of the country, also reviving the historic English claim to the French throne.
