Maharaja Nabakrishna Deb (1733–97), founder of the Shobhabazar Rajbari royal family (at 35), started life as a modest aristocrat but soon amassed enormous wealth in his service to the British, in particular by his role in assisting to topple
Siraj ud-Daulah. During his lifetime Maharaja Nabakrishna Deb built two palaces, together the largest palace in Calcutta. The palace at 35 Raja Nabakrishna Street (known as
Shobhabazar Rajbari or "Baag ola Bari - Palace with the lions"), on the northern side of the road, was the one first constructed by him, subsequently inherited by his adopted son from his elder brother
Gopimohan and his descendants including his son
Raja Radhakanta Deb. The palace at 33 Raja Nabakrishna Street (known as
Choto Rajbari) was built by him when a son was born to him later in life, and was left to his biological son Raja Rajkrishna and his descendants. ==Role in cultural and social life of Bengal==
