Urther, the High-King of Britain fell in love with the Lady Igraine, but she was already married to Gorlois, the Duke of Tintagel.
King Uther decided he must marry Igraine. So he took his army and fought with Gorlois. Gorlois was killed. King Uther married Igraine and they had a son named Arthur. He was born at Tintagel Castle.
This was a very dangerous time and attacks by Saxons happened a lot. So King Uther gave his baby son to his wizard, Merlin, for safety Merlin sent Arthur away to be raised in the countryside by Sir Ector.
When Arthur was 15 Years old, his foster brother Kay was going to his first Jousting tournament. For all these years the Sword in the Stone was still not pulled out. After forgetting Kay's sword, Arthur went looking for a new one and pulled the sword out of the stone.
