Andhras were very much agitated over the developments in the State of Hyderabad during the years 1946--48. The Nizam was very anxious to become independent and he insisted that Hyderabad should be the third dominion. He tried to achieve his ambitious desire with the help of Khasim Razvi of the Ittehadul Muslimeen and its storm-troopers, the Razakars.
Meanwhile, the Hindus of the Hyderabad State who accounted for 93 per cent of its population, launched the `Join India' movement with the cooperation of a few patriotic Muslims for the integration of the State with the rest of the country. The State Congress leaders, led by Swami Ramanand Tirtha, invoked themselves whole-heartedly in the movement. As the State Congress was banned by the Nizam, its leaders conducted their activities from places like Vijayawada and Bombay. The Communists on their part organised village defence squads to protect the villagers from the attacks of the Nizam Police and Razakars.
All negotiations between the Nizam's Dominions and the Indian Union proved abortive. The Nizam Government did not agree to the accession of the Dominions to the Indian Union. The activities of the Majlis Ittehadul Muslimeen and the Razakars within the Dominions were posing a threat to peace and harmony. The growing violence of the Razakars seriously jeopardised law and order. The Government of India, tried to make the Nizam see reason and sign the Instrument of Assession with India. After tortuous negotiations, the Nizam finally entered into a `Stand Still Agreement' on November 29, 1947, with India for one year to maintain status quo, which existed between the British and the Nizam before August 15, 1947. This agreement of the Nizam was only to gain time to procure military hardware from different parts of the world and smuggle them into Hyderabad. In the meanwhile, the Nizam sent a delegation to the U.N.O. to refer the Hyderabad case to the Security Council.
With the growing violence by the Razakars and the Nizam's attempts to get himself independent, the Government of India decided to curb these tendencies by launching a `Police Action' against the Nizam. On the 13th of September, 1948 `Police Action' on Hyderabad commenced. The Indian Army, led by Major-General J.N.Chaudhuri entered the State from five directions and the military action was a brilliant success. On 18th September, 1948, Nizam's forces surrendered and Mir Laik Ali, the Prime Minister of the Nizam, and Khasim Razvi were arrested. On September, 23, the Nizam withdrew his complaint in the Security Council. The merger of Hyderabad Dominions into the Indian Union was announced. Major-General J.N.Chaudhuri took over as Military Governor of Hyderabad and stayed in that position till the end of 1949. In January 1950, M.K.Vellodi, a Senior Civil Servant, was made the Chief Minister of the State and the Nizam was designated `Raj Pramukh'. After the 1952 General Elections, the first popular ministry headed by B.Rama Krishna Rao took charge of the State.
