Explanation:

Bhopal State was the second-largest Muslim-ruled princely state: the first being Hyderabad. After the independence of India in 1947, the last Nawab expressed his wish to retain Bhopal as a separate unit. Agitations against the Nawab broke out in December 1948, leading to the arrest of prominent leaders including Shankar Dayal Sharma. Later, the political detainees were released, and the Nawab signed the agreement for Bhopal's merger with the Union of India on 30 April 1949. The Bhopal state was taken over by the Union Government of India on 1 June 1949.
