According to English legend, Arthur became king when he managed to pull a sword out of a stone. Although people were surprised when he was crowned, he proved to be a good king. He married Guinevere, whose father gave Arthur a round table as a wedding present. Arthur's knights sit around this table, and they were known as the Knights of the Round Table. One of Arthur's knights, Lancelot, was falling in love with Guinevere, and when Arthur found out, he went to fight him. While Arthur was fighting the war against Lancelot, his nephew Mordred was stealing his kingdom and his queen. Arthur returned and killed Mordred, but he was badly injured. People thought that he was taken away to the island of Avalon. Some people believed that he died. Others thought that he didn't die and that he would return when Britain needed him.
