Some historians identify him as the Kulankayan Cinkai Ariyan[5] mentioned in the Jaffna Tamil chronicles, stating that Kulanka is actually a corruption of Kalinga.
Having executed Parakrama Pandya and ransacked the temples of Anuradhapura and Polonnaruwa, Magha was crowned king by his own soldiers from Kerala and settled in the capital of Pulatthinagara.
From these places the various nobles 'gave as little heed to the infamous army of the Ruler Magha, though ... as to a blade of grass and protected without fear that district and the Order [of Buddhist monks]'.
[24] The man who eventually emerged as the leader of the resistance was Vijayabahu III, who the chronicles identify as a descendant of Sirisamghabodhi (242-244 or 251–253),[25] a king of Rajarata, though it is possible that the relationship was through marriage.
[27] Vijayabahu's most emphatic statement of authority however was the recovery of the two sacred relics (around 1222), which he paraded through the lands he controlled and invested in a freshly constructed temple.
Vijayabahu's reign was largely spent reconstructing the shattered Buddhist infrastructure of the Sinhalese in Mayarata, and indeed many of the religious traditions he established were to last into modern times.
[28] Occasionally raids into Kalinga-controlled territory were mounted, but it was not until the reign of is son, Parakramabahu II(1234–1267) that a concerted effort was made to drive the invaders out from Polonnaruwa Kingdom.
[29] It would appear however that Magha had retreated to the Jaffna Kingdom and ruled until the throne was secured by Chandrabhanu,[30] but the chronicles make no mention of him taking part in the wars between Parakramabahu and the Kalinga.
