How does Oedipus respond to the plague in Thebes?

Oedipus responds to the plague in Thebes by vowing to find and punish the murderer of King Laius. This reflects his character as a determined and proactive leader who is deeply concerned about the welfare of his city and its people. At the beginning of the play, Oedipus is portrayed as a ruler who is willing to take action in the face of suffering. He recognizes that the current plague is a punishment sent by the gods due to the unresolved crime of Laius's murder, and he believes that only by addressing this crime can he relieve the city of its afflictions.

Oedipus's commitment to uncovering the truth about Laius’s death demonstrates his sense of responsibility and his resolve to protect his city. This action sets the stage for his tragic journey, as his investigation leads him to uncover disturbing revelations about his own identity and fate. This response is a crucial turning point because it showcases both Oedipus's strengths as a leader and the tragic irony that will unfold as the play progresses.
