This practice of shared rule with one prince asserting primacy was common in the Pandyan Kingdom.
Bhuvanaika Bahu's successor Parâkkamabâhu III went on a personal embassy to Kulasekaran's court and persuaded him to return the relic.
[8] Kulasekaran's long rule of about four decades was one of peace and prosperity according to the foreign travelers who visited the Pandyan country during his reign.
The Persian historian Abdulla Wassaf of Shiraz describes the country under Kulasekaran as the most agreeable abode on earth and the most pleasant quarter of the world.
He also claims that an Arab Muslim named Takiuddin Abdur Rahman, son of Muhammadut Tibi, was appointed by Kulasekara Pandyan as the prime minister and adviser.
[9] He gifted a piece of land from his leisure park (Vasantha mandapam) to Kazi Syed Tajuddeen who came from Oman and settled in Madurai.
[citation needed] Wassaf's accounts which refer to Kulasekaran as Kales Dewar say he ruled for "forty and odd" years, "during which time neither any foreign enemy entered his country, nor any severe malady confined him to bed" and that the treasury of the city of Mardi (Madurai) had "1,200 crores of gold not counting the accumulation of precious stones such as pearls, rubies, turquoises, and emeralds.
[11] It must be mentioned that Wassaf himself never visited any part of India and is generally considered an unreliable source by scholars.
Accounts from Muslim historians Wassaf and Amir Khusrow say he was killed by Jatavarman Sundara Pandyan III in 1310 CE.
