When the Earl of Warwick learned of Edward's marriage, he was angry. He grew even more angry as time went on, because Elizabeth's family became powerful and the king no longer respected Warwick as he had done in the beginning. In 1459 he rebelled against the king, with help from another of Edward's younger brothers, George, Duke of Clarence; George was married to the Earl of Warwick's elder daughter, Isabel. The rebels went to France and made an alliance with Queen Margaret, who was the wife of King Henry VI. The Earl of Warwick managed to defeat King Edward in battle in 1471, and freed King Henry VI from prison. Henry was now king again, and Edward had to escape to Burgundy, while his wife and children went into hiding.
