House of Siri Sanga Bo

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 defeated 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 until late 13th century and Pandyan expedition plundered the fortress of Subhagiri (Yapahuwa) and returned with the Relic of the tooth of the Buddha. This expedition took place near the end of the Sri Lankan king Bhuvanaikabâhu I's reign (1272-1285 CE). Bhuvanaika Bahu's successor Parâkkamabâhu III went on a personal embassy to Kulasekaran's court and persuaded him to return the relic. So there can be said that king Parakramabhahu faced heavy problems at the moment on the sitting throne. So there could conclude that after solving the majority of problems he had taken the throne officially after a coronation. This can show by a Tamil poem called Sarajoti Malai which was recited at King Parakramabhahu III in May A.D.1310 which was the seventh year after his coronation. Then it can be said his reign was started in A.D.1302 or A.D.1303. In the meantime can be taken as a turbulent period in Sri Lanka. It can also be said that a large part of Sri Lanka has become part of the Pandyan Empire. They had to change their capital city to Dambadeniya, Yapahuwa and Kurunagala because of continuous invasions from southern India.
