Edward V
Edward V was born in Westminster Abbey in November 1470 while his father was in exile in the Netherlands (for a short time). He was the son of King Edward IV and Elizabeth Woodville. Edward’s sister Elizabeth of York later married Henry VII. This marriage was a part of the so-called "Tudor Myth" because Elizabeth was from the house of York and Henry VII from the house of Lancaster (also have a look at Tudor Rose. Edward’s younger brother was called Richard. Young Edward was made Prince of Wales in 1471 and stayed there for the whole time of his father's reign. After the death of his father in April 1483 he became king for a very short time.
His uncle Richard III “Duke of Gloucester” exercised his royal power as lord protector of the realm because Edward was a minor. On June 1483 he put Edward and Richard into the Tower of London where they were murdered. There are rumours that Richard ordered the murder of the boys to become king himself.
