After the conquest of Rajarata, he moved the capital to the Jaffna peninsula which was more secured by heavy Vanni forest and ruled as a tribute-paying subordinate of the Chola empire of Tanjavur, in modern Tamil Nadu, India. During this period (1247), a Malay chieftain from Tambralinga in modern Thailand named Chandrabhanu invaded the politically fragmented island. Although King Parakramabahu II (1236–1270) from Dambadeniya was able to repulse the attack, Chandrabhanu moved north and secured the throne for himself around 1255 from Magha. Sadayavarman Sundara Pandyan I invaded Sri Lanka in the 13th century and defeated Chandrabhanu the usurper of the Jaffna Kingdom in northern Sri Lanka. Sadayavarman Sundara Pandyan I forced Chandrabhanu to submit to the Pandyan rule and to pay tributes to the Pandyan Dynasty. But later on when Chandrabhanu became powerful enough he again invaded the Singhalese kingdom but he was defeated by the brother of Sadayavarman Sundara Pandyan I called Veera Pandyan I and Chandrabhanu lost his life. Sri Lanka was invaded for the 3rd time by the Pandyan Dynasty under the leadership of Arya Cakravarti who established the Jaffna kingdom.
