@snowywinter: Yes, Oedipus was the King. Sophocles was a playwright and “Oedipus the King” is considered to be his most representative work. Oedipus is the most played tragedy of all Greek theater.
As the article stated, the oracle predicted that King Laius would be “doomed/to perish by the hand of his own son.” Laius decided to deliver his son to a servant with orders to kill him. The servant cannot fulfill the king’s orders and, instead, leaves the baby in a field. A shepherd who gives the baby to another shepherd rescues Young Oedipus. It ended up that Oedipus was raised in the court of childless King Polybus of Corinth.
Oedipus was curious as to who his real parents. The Delphic Oracle tells him he is destined to mate with his mother and kill his father. He goes off to try to find his birth parents and meets Laius, his real father, along the way. He has no idea that this was his father. They argue and he kills Laius.
He arrives at the kingdom in Thebes, which is protected by the curse of the Sphinx. Oedipus has to solve a riddle. The curse of the kingdom is overthrown and Oedipus’s reward is to have the kingship and the hand of the queen Jocasta, his biological mother.
