Princes in the Tower
It is unclear what happened to the boys after the last recorded sighting of them in the tower. It is generally assumed that they were murdered; a common hypothesis is that they were killed by Richard in an attempt to secure his hold on the throne. Their deaths may have occurred sometime in 1483, but apart from their disappearance, the only evidence is circumstantial. As a result, several other hypotheses about their fates have been proposed, including the suggestion that they were murdered by Henry Stafford, 2nd Duke of Buckingham or Henry VII, among others. It has also been suggested that one or both princes may have escaped assassination. In 1487, Lambert Simnel initially claimed to be Richard, Duke of York, but later claimed to be Edward Plantagenet, 17th Earl of Warwick. From 1491 until his capture in 1497, Perkin Warbeck claimed to be Richard, Duke of York, having supposedly escaped to Flanders. Warbeck's claim was supported by some contemporaries (including the aunt of the disappeared princes, Margaret of York).
