Hambir Malla Dev, also known as Bir Hambir(Beera Hambeera) & Veer Hambir, was the forty-ninth king of the Mallabhum.He ruled from 1565 to 1620 CE.
Bir Hambir was a pious man who started following Vaishnavism. A story in two Vaishnava works (Prem-vilasa of Nityananda Das (alias Balaram Das) and Bhakti Ratnakara of Narahari Chakrabarti) recounts the manner in which Srinivasa and other devotees were robbed by Bir Hambir while travelling from Vrindavan to Gaur with a number of Vaishanava manuscripts. However, Bir Hambir was so moved by Srinivasa’s reading of Bhagavata that he converted to Vaishnavism and gave Srinivasa a rich endowment of land and money. He introduced the worship of Madan Mohan to Bishnupur
