Martanda Cinkaiariyan accompanied Battuta to the peak of Sivanoli Padam Malai along with Yogis and other Hindus and companions of the king who visited the sacred Shiva site annually.
Ibn Battuta mentions that the King had a large navy, and was seen trading in pearls, cinnamon and ahil and had cordial relationship with Indian rulers.
[1][2] The primary source such as Yalpana Vaipava Malai records that Martanda was forced to subdue Vanniar chieftains from the Vanni region who had rebelled against him.
An inscription dated in the 3rd regnal year of Vikramabahu III (1357–1374), found at the Medawala Rajamaha Vihara in the Kandy District records a treaty between that king and an Aryacakravarti named Martanda (Sin ai Ariyan) of Jaffna.
The Rajaveliya a primary source written during that period too refers to the fact that the Aryacakravartis collected taxes from Udarata and Southern lowlands.
