Pamheiba

Meidingu Pamheiba was an king of Manipur in the early 18th century. After conversion to Hinduism, he made it the official religion of Manipur in 1717 and took the name Gharib Nawaz. Although of Naga origin himself, he displayed hostility towards the Thangal Naga. During most of his reign he was engaged in warfare against the Kingdom of Burma.

He was born on December 23, 1690 CE in Manipur to Pitambar Charairongba and was crowned Meidingu on Wednesday, the 23rd of thawan 1631 Saka Era. During the early 18th century, Hindu missionaries from Sylhet arrived in Manipur to spread Gaudiya Vaishnavism. They were led by Shantidas Goswami and his associate Guru Gopal Das who succeeded in converting the King from the old Meitei religion to Vaishnavism in 1710. Later during his reign, Pamheiba made Hinduism the official religion, and converted nearly all the Meitei people to Hinduism.
