In 1608, Emperor Jahangir appointed Islam Khan Chishti as the Subahdar of Bengal, who continued his predecessors' campaigns to subdue the Baro-Bhuiyans and completely annex all of Bengal to the Mughal Empire. He sent a letter to Ramchandra requesting him to surrender and recognise Mughal subordination. Ramchandra rejected the letter and teamed up with Pratapaditya to develop a large army consisting of thousands of Bengalis and Afghans who were opposed to Mughal rule.
