Battle of Venni (c. 190 CE[2][1]) was a military engagement fought by the early historic Chola ruler Karikala against a confederacy led by the Pandya and Chera rulers.
[2] A confederacy of eleven rulers, led by the Chera and Pandya, including several minor velir chieftains, were defeated at Venni.
[2] The Chera ruler, named "Cheraman Perum Cheralathan", was wounded on the back while leading the warriors (pierced by a shaft).
Not being able to bear the disgrace, he committed suicide by slow starvation ("sitting by facing the north").
[2] The Chera ruler generally is identified with Adu Kottu Pattu Cheralathan.
