Origin
The Musahar were traditionally rat catchers, and there is still uncertainty as to their exact origin. This Hindu Mythology story shows how they are perceived in the traditional Indian and Madhesi Nepali society, Parmashwar (the Hindu creation god) created man and gave him a horse to ride. The first Musahar decided to dig holes in the belly of the horse to fix his feet as he rode. This offended Parmeshwar, who punished them by making them rat catchers.They are found in eastern Uttar Pradesh, Bihar and north Madhya Pradesh and Terai region of Nepal. The Musahar speak the Bhojpuri dialect of Hindi and Nepali.
