Perkin Warbeck was a pretender to the English throne claiming to be Richard of Shrewsbury, Duke of York, who was the second son of Edward IV and one of the so-called "Princes in the Tower". Richard, were he alive, would have been the rightful claimant to the throne, assuming that his elder brother Edward V was dead and that he was legitimate—a point that had been previously contested by his uncle, King Richard III.

The House of Tudor was an English and Welsh dynasty that held the throne of England from 1485 to 1603. They descended from the Tudors of Penmynydd, a Welsh noble family, and Catherine of Valois. The Tudor monarchs ruled the Kingdom of England and the Lordship of Ireland for 118 years with five monarchs: Henry VII, Henry VIII, Edward VI, Mary I and Elizabeth I. The Tudors succeeded the House of Plantagenet as rulers of the Kingdom of England, and were succeeded by the Scottish House of Stuart. The first Tudor monarch, Henry VII, descended through his mother from the House of Beaufort, a legitimised branch of the English royal House of Lancaster, a cadet house of the Plantagenets. The Tudor family rose to power and started the Tudor period in the wake of the Wars of the Roses (1455–1487), which left the main House of Lancaster extinct in the male line.
