Siwan District is one of the districts of Bihar state, India. Siwan town is the administrative headquarters of this district. Siwan district is a part of Saran Division since 1972. The town is known for its great past especially for First President of Indian Republic who belonged to Jeeradei

Siwan district, situated in the western part of the state, was originally a sub-division of Saran district, which in ancient time formed a part of Kosala Kingdom. Siwan became a fully-fledged district when it was split from Saran in 1976.

Siwan derived its name from “Shiva Man”, a Bandh Raja whose heirs ruled this area till Babar’s arrival. The meaning of “Siwan” is border, previously it used to be the border district of “Bihar”. Maharajganj, which is another subdivision of Siwan district, may have found its name from the seat of the Maharaja there. A recently excavated marvelous statue of Lord Vishnu at Bherbania village from underneath a tree indicates that there were large numbers of followers of Lord Vishnu. Currently, it is not located as border district of Bihar. The Gorkha king had briefly extended his kingdom to Siwan for a few years in the 1790s before the British started their rule and repulsed the Gorkhas and that is how the name of Siwan (meaning border) got stuck to the region
