Alliance Through Marriage

The exile year ends when the Kaurava army, suspecting the Pandavas may be hiding in Matsya, raids Virata's cattle, and Arjuna, breaking cover, single-handedly defeats the attacking force while still disguised as the eunuch dance master Brihannala, an episode that finally reveals the five brothers' true identities to Virata and his court. Grateful and now firmly allied with the Pandavas, Virata offers his daughter Uttara in marriage, not to Arjuna himself, who declines on the grounds that he had spent a year in her close company as her teacher and regards the match as inappropriate, but to Arjuna's son Abhimanyu, cementing the alliance across a generation instead. This marriage carries lasting weight in the epic: Uttara and Abhimanyu's union produces Parikshit, who survives the devastation of the Kurukshetra war, in which Abhimanyu himself is killed and Virata's own sons die fighting on the Pandava side, and who becomes the sole heir to carry the Pandava line forward after the war's end.

Virata therefore matters to the Mahabharata's larger structure beyond the single book that bears his name: his kingdom supplies both the protective cover the Pandavas needed to fulfill their exile and the dynastic marriage that would ultimately preserve their bloodline once the war had killed almost everyone else who might have continued it.
