How Samastipur got its name !
When Tirhut was divided into two parts by Haji Ilyas of Bengal, the king transferred his capital to Sugauna near Madhubani. In this way, the southern part of the district was under Haji Ilyas and the northern part under the Oinwaras.
Haji Shamsuddin Ilyas of Bengal founded the modern sub-division of Samastipur, though it was originally Shamsuddinpur, which later on became Samastipur.
Sultan Firuz Tughlaq was a close friend of Oinwar Bhogiswara and Vidyapati confirms this point. Birasingh and Kirtisingh of this dynasty went to Jaunpur along with Vidyapati to seek the help of Ibrahim Shah Sarqui against Arslan who had usurped power in Mithila.
