The Bardhaman Raj (also known as Burdwan Raj) was a zamindari estate that flourished from about 1657 to 1956, first under the Mughals and then under the British in the province of Bengal in India. At the peak of its prosperity in the eighteenth century, the estate extended to around 5,000 square miles (13,000 km2) of territory and even up to the early twentieth century paid an annual revenue to the government in excess of ₹33 lakh (US$49,000).
