Hathwa Raj also known as the Kalyanpur chieftaincy was a chieftaincy established in what is now Saran division of Bihar. It comprised 1,365 villages across Chhapra, Siwan, and Gopalganj districts of Bihar, with a population exceeding 391,000 and generating an annual revenue of nearly one million rupees at the time of independence. Earlier seats of the Raj included Huseypur, Kalyanpur, Balchowra and Baghoch. The Kalyanpur chieftaincy was subjugated by the Mughal Emperor Akbar during late 16th century.
