Jaffna kingdom
With the death of Ethirimana Cinkam in 1617, Cankili II, a usurper, took control of the throne after killing the regent nominated by the late king. Unable to secure Portuguese acceptance of his kingship, Cankili II through Migapulle Arachchi invited military aid from the Thanjavur Nayak kingdom and allowed corsairs from Malabar to use a base in Neduntivu, hence posting a threat to Portuguese shipping routes through Palk Straight. Cankili II was supported by the Kandyan rulers. After the fall of the Jaffna kingdom, the two unnamed princesses of Jaffna had been married to Senarat's stepsons, Kumarasingha and Vijayapala. Cankili II expectably received military aid from the Thanjavur Nayak Kingdom. On his part, Raghunatha Nayak of Thanjavur made attempts to recover the Jaffna Kingdom for his protege, the Prince of Rameshwaram . However, all attempts to recover the Jaffna Kingdom from the Portuguese met with failure.
