What is the story about King Arthur

King Arthur was actually an orphan by birth and he was treated under the care of his uncle. Once what happened was that Arthur and his uncle and his cousin went to watch a show of the emperor in his kingdom While they reached there his uncle had forgotten his sword in the church. He said Arthur to fetch it for him. He went to the church and started looking for the sword. The event was actually that who ever would remove the magical sword given by the GODS will become the King of the particular empire and the place where the sword was kept was in the church and when Arthur saw the sword he thought this is the sword of his uncle and went away from there. When he returned he showed his uncle his sword. The uncle was terrified to see that Arthur was the one who had removed the sword and thus he told the emperor all the things he saw. And on that sword was written that, " there will be only one boy who could remove that mystical sword" and that was King Arthur.
