What reason does Creon give for issuing his edict?

Creon's edict is primarily motivated by the need to ensure political stability following the civil war that resulted in the deaths of Eteocles and Polyneices. After a time of unrest and conflict within Thebes, Creon believes that a strong and decisive leadership is crucial to prevent further disorder. His proclamation serves as a declaration that loyalty to the state and its laws will be paramount in restoring order and promoting the well-being of Thebes.

While there are elements of establishing authority and punishing traitors within the context of the edict, the overarching goal of maintaining stability after the chaos of war underscores Creon's reasoning. By prioritizing this stability, he aims to demonstrate a firm governance that will discourage dissent and reinforce societal norms in the aftermath of strife.
