The Bardhaman Raj, also known as Burdwan Raj, was a zamindari Raja estate that flourished between 1657 and 1955 in the Indian state of West Bengal. Maharaja Sangam Rai Kapoor, a Punjabi Khatri from Kotli mahalla in Lahore, Punjab, who was the first member of the family to settle in Bardhaman, was the original founder of the house of Bardhaman, whereas his grandson Abu Rai, during whose time the zamindari started flourishing, is considered to be the patriarch of the Bardhaman Raj family.
