Siwan is situated on the alluvial plains of the Ganga basin, in the western part of north Bihar. The district shares its western boundary with the state of Uttar Pradesh, while Gopalganj lies to its north, Saran to its south and east, and parts of Deoria and Kushinagar districts of Uttar Pradesh adjoin it on the west. The Daha and Jharahi rivers flow through the district. The terrain is largely flat and agricultural, with paddy, wheat, sugarcane and pulses being the principal crops.
The region of Siwan has a long historical association with the ancient Mahajanapada of Kosala and later with the Magadhan polity. The town's name is popularly traced to a Bandh chieftain who is said to have ruled the area in earlier centuries. The historic site of Don in the district has been associated with traditions linked to the Mahabharata and to the teacher Dronacharya. Another notable site is Bhikha Bandh and the area around Mahendra Nath temple at Mehandar, an old Shaiva pilgrimage centre.
Under British rule, Siwan was a subdivision of Saran district. It was constituted as a separate district on 3 December 1972 by separating it from Saran.
The city is administered by the Siwan Municipal Council (Nagar Parishad), responsible for water supply, sanitation, street lighting, road maintenance and local taxation. The district administration is headed by a District Magistrate, while law and order is supervised by a Superintendent of Police. Siwan town also hosts the district court and other district-level offices.
Siwan is a Lok Sabha parliamentary constituency and also gives its name to a Vidhan Sabha (Bihar Legislative Assembly) constituency. The district contains several other assembly seats including Ziradei, Darauli, Raghunathpur, Daraundha, Goriakothi, Maharajganj and Barharia (with constituencies revised over time as per delimitation).
The economy of Siwan is predominantly agrarian. Sugarcane cultivation historically supported sugar mills in the wider region, while paddy and wheat dominate food-grain output. The town acts as a market and trading hub for agricultural produce. A significant portion of households depend on remittances from family members working in other Indian states and in Gulf countries, a pattern common across western Bihar.
Siwan Junction is a major railway station on the Chhapra–Gorakhpur main line of the North Eastern Railway zone. It is a junction from which branch lines diverge towards Thawe (Gopalganj) and Mairwa, providing connectivity to other parts of north Bihar and eastern Uttar Pradesh. The station handles long-distance trains linking Siwan with Delhi, Kolkata, Mumbai, Patna, Lucknow and other major cities.
Siwan is connected by National Highway and State Highway networks to Chhapra, Gopalganj, Gorakhpur and Patna. State transport and private buses operate regular services to neighbouring towns and to Patna, the state capital.
Siwan hosts a number of degree colleges affiliated to Jai Prakash University, Chhapra, including D.A.V. College, Siwan and Z.A. Islamia College. There are several government and private senior secondary schools, and the district has institutions for teacher training and vocational education.
The population of Siwan town and district is largely Hindi- and Bhojpuri-speaking, with a significant Urdu-speaking Muslim population. The cultural life of the region reflects the broader Bhojpuri heartland, with festivals such as Chhath, Holi, Diwali, Eid, and Muharram observed prominently. Folk traditions including Bhojpuri songs, regional cuisine such as litti-chokha, and seasonal fairs at temple sites form part of the local culture.
