How was Hercules marriage arranged?

Hercules' marriage to Megara was arranged as a reward for his bravery and service to Thebes. After he successfully defended the city from a siege, King Creon offered Megara, his daughter, to Hercules as a prize. This union, however, was fraught with tragedy, as Hercules later faced madness induced by Hera, leading him to unintentionally harm his family, including Megara.
