After killing two brothers, Eteocles and Polynices, in a duel with each other, Creon becomes the king of Thebes. He orders that Polynices and others who fought against the country are not buried. This is where the conflict begins between Antigone, who defends the unwritten laws of conscience, of blood ties with his brother, and Creon, who defends the written laws of the state. Creon’s order that he will sentence to death anyone who dares to bury Polynices, declared a traitor, is opposed by Antigone, who, regardless of anything, buries her brother.
Sophocles himself in his tragedy defends the written state laws, to the extent that they do not violate the unwritten moral laws, rooted in the human conscience.
