Vira Bahu I (1196) was son of Nissanka Malla and king of the Kingdom of Polonnaruwa, in present-day Sri Lanka. He came to the throne after his father's death, however only managed to reign for less than a day, being crowned at night and slain at dawn by the commander-in-chief of the army, Tavuru Senevirat on the grounds that he was a son not equal to his father.[1] [2]
