Akbar, the Mughal emperor of Delhi, was the head of the three regional powers of Bengal, Hyderabad and Ayodhya.
Akbar appointed the Rajput king ManSingh as Subedar of Bihar in 1588, then he was given the post of commander in the Mughal court.
To stop the looting, king Man Singh brought a very brave and fighting warrior community from UttarPradesh and Rajasthan to Bengal.
In West Bengal, although the Chain community is widely dispersed through the state, the Government granted Scheduled Castes (SC) status only to Chain members in four districts: Malda, Murshidabad, Nadia and Dakshin Dinajpur.
The National Commission for Scheduled Castes was reported in 2015 to be initiating a process to extend SC status to the community throughout West Bengal.
