When the South Indian invader Kalinga Magha conquered the Polonnaruwa city in 1215 A.D., the royals, chieftains and other inhabitants rejected the policy of continuous harassment and unjust ruling of Magha and moved towards the southwest and formed administrative units in several places and tried to continue the Sinhalese inheritance power as it is said in chronicles.
The king Vijayaba became as the Vijayaha iii, who managed to overcome the other chieftains and brought the island in to one umbrella. Thereafter Dambadeniya administration becomes the third kingdom of Sri Lanka.
The historians are of the opinion that the tooth relic and the bowl relic of Buddha which had been concealed for safety in Kothmale had been brought to the rock temple of Beligala and constructed a shrine room for the tooth relic. He also has constructed another temple called Wijayasudarrama in Dambadeniya town in his name.
The most remarkable mission of the King Parakkramabahu ii, who is the eldest son of the King Vijayabahu iii, is expelling the Kalinga Magha invader from the island.
Thereafter the tooth relic at Beligala temple was brought to the Dambadeniya kingdom and temple for tooth relic constructed closer to the royal palace.
The king has constructed a rampart and a parapet wall to establish the security of the city and the palace.
