"The details of the conversion of Raja Ganesh bring out the importance of the role of force, of persuasion and of the Ulama and Sufis in proselytization. In 1409 Ra a Ganesh occupied the throne of Bengal and sought to establish his authority “by getting rid of the prominent ulama and Sufis”. Qutb-ul-Alam Shaikh Nurul Haqq wrote to Sultan Ibrahim Sharqi to come and save the Muslims of Bengal. Ibrahim Sharqi responded to the call, and Raja Ganesh, finding himself too weak to face the challenge, appealed to Shaikh Nurul Haqq for help. The latter promised to intercede on his behalf if he became a Musalman. The helpless Raja was willing, but his wife refused to agree. Ultimately a compromise was made by the Raja offering to retire from the world and permitting his son, Jadu, to be converted and ascend his throne. On Jadu being converted and enthroned as Jalaluddin Shah, Shaikh Nurul Haqq induced Sultan Ibrahim to withdraw his armies.87 If a Raja of the stature of Ganesh could not face up to the Ulama and the Sufis, other Rajas and Zamindars were still worse placed. Petty Rajas and Zamindars were converted to Islam, with their wives and children, if they could not pay land revenue or tribute in time. Such practice appears to be common throughout the whole country as instances of it are found from Gujarat88 to Bengal."
