Mahendra of Dakshina Kosala

He was one of the many kings who were subjugated, captured and later released by the powerful Gupta emperor Samudragupta on his Dakshinapatha (Southern India) campaign.

Mahendra of Kosala was one of the southern kings of Dakshinapatha paying allegiance and tribute to Samudragupta.

[5] Other theories suggest that he was a king of a branch the Ikshvaku dynasty, who had established a mighty kingdom in the south.

[1][6] Yet another theory identifies Mahendra with a Nala king named Mahendraditya.

[7][8] The Allahabad stone pillar inscription of Samudragupta's lines which include Mahendra's name in it goes as follows-

"Mahendra of Kosala" ( Brahmi script : Kausalaka Mahendra ) in Line 19 of the Allahabad Pillar inscription of Samudragupta (r.350-375 CE)
