Richard III. (1452‒1485)

Richard III., king of England from 1483 to 1486, youngest brother of Edward IV., and last of the Plantagenets, born at Fotheringhay Castle; in 1461 was created Duke of Gloucester by his brother for assisting him to win the crown; faithfully supported Edward against Lancastrian attacks; married (1473) Anne, daughter of Warwick, the King-Maker; early in 1483 was appointed Protector of the kingdom and guardian of his young nephew, Edward V.; put to death nobles who stood in the way of his ambitious schemes for the throne; doubts were cast upon the legitimacy of the young king, and Richard's right to the throne was asserted; in July 1483 he assumed the kingly office; almost certainly instigated the murder of Edward and his little brother in the Tower; ruled firmly and well, but without the confidence of the nation; in 1488 Henry, Earl of Richmond, head of the House of Lancaster, invaded England, and at the battle of Bosworth Richard was defeated and slain (1452‒1485).
