House of Siri Sanga Bo was a powerful dynasty which ruled parts of Sri Lanka from Vijayabahu III of Dambadeniya (1220–1224) until Rajasinha I of Sitawaka (1581–1591). Vijayabahu III of Dambadeniya routed Kalinga Magha's armies from Maya Rata and established his fortress at Dambadeniya. This dynasty was able to protect their independence by facing so many foreign invasions thereafter. They had to change their capital city to Dambadeniya, Yapahuwa and Kurunagala because of continuous invasions from southern India.
