The Wijayaba Kollaya (Sack of Vijayabahu) took place in the Kingdom of Kotte on the island of Ceylon (now Sri Lanka) in 1521. The three sons of King Vijayabahu VI mutinied against their father, killing him, and divided the Kingdom among themselves. The three sons were products of the king's first marriage and were named Bhuvanekabahu (later Bhuvanekabãhu VII of Kotte), Pararajasingha (later Raigam Bandara) and Mayadunne (later Mayadunne of Sitawaka). Queen Kiravella, whom the king married second, had a son named Deva Rajasinghe by her previous marriage. The princes overheard that the king intended to make Devaraja the heir to the throne, at the request of his second queen, and became hostile to the king, and hired a foreigner to murder the king in the palace.
