Nadia Raj was a dynasty of Zamindars and the rulers of territories that are now part of the Nadia district region of West Bengal, India.
[3][4] The estate of Nadia Raj was estimated to cover an area of 8,161 square kilometres (3,151 sq mi).
[6] The Nadia Raj family claims descent from Bhatta Narayana,[7][8] who was a Kanyakubja Brahmin of the Sandilya Gotra.
He was summoned from Kanyakubja (Kannauj) by Raja Adisura of Bengal, for the conduct of ceremonies of purification.
Since the establishment of British rule in Bengal each of the Rajas of Nadia were created a Maharaja Bahadur in succession.
