From about 1609 to about 1769 the Sen kings of Makwanpur were nominal kings of Morang and allied to the other five kings of Limbuwan. The era of the Sen dynasty in Limbuwan began with the conquest of the Morang kingdom by King Lo Hang Sen to avenge the death of the prime minister of Morang. They were Hindus of present-day Bihar and Terai region.
