King of England (1422-1461 and 1470-1471) who as an infant succeeded his father, Henry V, and for most of his reign exercised little power. He was taken prisoner in the Yorkist victory at Northampton (1460), and Edward IV was proclaimed king (1461). Rescued from captivity, Henry regained the throne (1470) but was recaptured at the Battle of Barnet and murdered in the Tower of London
