His son Kirit Bikram Kishore Deb Barman succeeds him, who was a minor at the time of the merger. As such, a regency council was formed to lead the administration under the presidency of Queen Kanchan Prava Devi, the widow of Bir Bikram Kishore. Prava Devi played an important role in the merger of Tripura in the Indian Union. After facing a crisis of both internal and external forces, she was put under pressure and decided to join the Indian Union. On the advice of the Indian government, she dissolved the Regent`s Council and was the sole regent on 12 January 1948. On September 9, 1949, she signed the “Tripura Merger Agreement” and was a member of the Indian Union effective October 15, 1949. It was then managed by the Chief Commissioner as a Category C state. The tragic death of the last king in power B.B. Bahadur Manikya was extremely unfortunate for Tripuri and in the history of tripuras. After his death, his grandson Kirri bikram Mannikya ascended to the throne of the Kingdom of Tripura, but he could not govern because he was a minor.
So his widow queen, Kanchan Prabha, took over the management of Tripura and took the administrative costs. She played an important role in the merger of The Tripser Kingdom into the Indian Union. Eventually, the merger treaty was signed by it and came into force on November 15, 1949, and the Kingdom of Tripura ceased to exist and was admitted to Class C of the Indian States. The Maharajah of Tripura ceded full and exclusive authority, jurisdiction and powers for and over governance to the Dominion government and agreed to transfer state administration to the Dominion government on October 15, 1949 (called after the day).  The state of Tripura, with its isolated position, which nevertheless occupies a strategic position on India`s eastern border, has an ancient history and a rich culture. However, the division of the country, in its train, posed to this small State a large number of problems which, in the current state of its development, were impossible to solve without assistance. The Government of India and Its Highness, the Regent of Maharani, have concluded, on behalf of the minor leader, that it is essential, in the interests of the State and its people and the country as a whole, that the Centre be held accountable for its management of the state and the well-being of its people. As of today, Tripura has become a centrally managed territory.  I am very grateful to Your Highness for coming to this agreement. Her task was not easy in the particular circumstances in which she found herself. I am sure that Providence will reward her for the courage and audacity with which she made this decision.
All I can say to the people of Tripura is that even though it is very far (and far away) from the capital of the country, it will always seek our attention and we will do our best to ensure that its ties with the main country are strengthened and that it is closer to us. They will not be alone in dealing with the many problems they face. They will have the resources and support of the centre to rely on. Through their cooperation and assistance, we hope that we will solve their problems effectively and effectively. May God bless our joint efforts successfully. 4. I hereby declare that, according to the Dominion of India, I am assured that an agreement will be reached between the Governor General and the sovereign of that State, according to which and the function of managing a law on domination in that state will be exercised by the sovereign of that state.
