When the Earl of Warwick discovered that the young king had married Elizabeth without his permission, he was furious. Although he was forced to accept the marriage, he became angry at the way Elizabeth's family grew powerful as a result of her becoming queen. A few years later, he turned against Edward and tried to put his rival, King Henry VI of England, back on the throne. While Edward was fighting to get his throne back, Elizabeth went to Westminster Abbey to find sanctuary; this meant that, because the abbey was a holy place, she could not be captured by her enemies as long as she remained there. While there, she gave birth to her first son, who was named Edward after his father. After a while, her husband returned and rescued her and her children, defeating the Earl of Warwick in battle and killing him.
