When Kauravas failed to defeat the Draupada (Panchal) army, Dronacharya sent Arjuna and his brothers for the task. Arjuna defeated Drupada, as ordered. Dronacharya took half of Drupada’s kingdom, thus becoming his equal. He forgave Drupada for his misdeeds, but Drupada desired revenge. He performed a Yajna to have a son who would slay Dronacharya and a daughter who would marry Arjuna. His wish was eventually fulfilled and thus were born Dhrishtadyumna, the slayer of Dronacharya, and Draupadi, the consort of the Pandavas.
