Jaffna kingdom
After Kalinga Magha invaded, with the intent of ruling the whole island, the Kingdom of Polonnaruwa was sacked. This caused massive Sinhalese migration to the south and west of the island. Unable to capture the whole island Kalinga Magha establishes the Jaffna kingdom becoming its first monarch. The Jaffna kingdom is situated in modern northern Sri Lanka while the Kingdom of Dambadeniya was established by Vijayabahu III on the rest of the island in around 1220.
