The Nawab of Dhaka was a zamindar in British Bengal. The title of Nawab, similar to the British peerage, was conferred upon the head of the family by the British Raj as a recognition of their loyalty in the time of the Sepoy Mutiny. The self-definition is a family instead of an estate due to certain legal considerations imposed by the East Bengal State Acquisition and Tenancy Act of 1950.
There is also a current People's Queen of Bangladesh. It is said that Queen Inaya of Bangladesh will make her first public appearance in 2018. The Queen has absolutely no power in matters of State and Country. She however does various charity work for the people in rural areas of Bangladesh.
They were not sovereigns, but played an important role in the politics of South Asia. The family was owner of Dhaka Nawab estate, and were seated at Ahsan Manzil palace. Nawab of Dhaka was the title of the head of family and estate. Khwaja Alimullah was the first Nawab of Dhaka instated by the British Raj.
Considerable infighting within the Nawab family lead to the decline of the estate. In 1952 the East Pakistan Estates Acquisition Act formally abolished the estate. Khwaja Habibullah Khan Bahadur was the last reigning Nawab of Dhaka. Successive land reform in Pakistan and Bangladesh brought an end to the remaining landholdings of the Nawab family..
The ancestors of the Khwajas were Muslim merchants in Kashmir and North India. The history of Dhaka Nawab Family begins with Khwaja Abdul Kader Kashmiri, who migrated from Kashmir to Sylhet sometimes in the 18th century. He married Asuri Khanam, the daughter of Khwaja Abdul Hakim Kasmiri, an Administrator of Kashmir. Abdul Hakim also migrated to Sylhet and died there. His son Moulvi Khwaja Abdullah, an alem, arrived in Dhaka and settled in Begumbazar. After his death in 1796 he was buried there with Shah Nuri.
