Wars of the Roses
Richard managed to win against a rebellion by his old friend, the Duke of Buckingham. Henry Tudor, a distant relative of Henry VI who returned to England, became the leader of the rebellions and created a new Lancastrian army. Elizabeth, Edward IV's widow, supported Henry after he promised to marry her daughter Elizabeth of York. In the Battle of Bosworth Field, Richard III was killed, and his army was defeated. Henry took the throne as King Henry VII, the first king of the House of Tudor.
