From http://coins.lakdiva.org/medievallanka/dambadeniya.html : VijayaBahu IV (1271-1273) now was sole king, but was assassinated, by his general Mitta, who seated himself on the lion throne. His younger brother, BhuvanaikaBahu succeeded in escaping; the usurper failing to secure allegiance of the south Indian mercenaries, who had been won over by the true heir, was murdered, and the BhuvanaikaBahu I (1273-1284) crowned and reigned eleven years. Early in his reign he had to deal with a Pandyan invasion, which he repelled ; thereafter he lived for a few years at Dambadeniya, and then removed to Yapahu. A Dhamila general Ariyacakkavattin laid waste Lanka and the sacred Tooth Relic and all the costly treasures he seized and made over to Pandu king Kulasekhara (1268-1308). BhuvanaikaBahu's son ParakramaBahu III (1302-1310) seeing no other means visited the Pandu King and by friendly negotiations, inclined him favourably and brought back the Tooth Relic to Lanka.
