Jaffna kingdom
Sadayavarman Sundara Pandyan I invaded Sri Lanka in the 13th century and defeated Chandrabanu the usurper of the Jaffna Kingdom in northern Sri Lanka. Sadayavarman Sundara Pandyan I forced Candrabhanu to submit to the Pandyan rule and to pay tributes to the Pandyan Dynasty. But later on when Candrabhanu 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 Candrabhanu 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.
