the Bahmani Sultanate, was established in south India by Ala-ud-Din Bahman Shah in a revolt against the Delhi Sultanate. The Qutb Shahi dynasty held sway over the Andhra country after the resolution of Vijayanagar empire by joint action of Mughals, Bijapur and Golconda sultanates. In the early nineteenth century, Northern Circars was ceded to the British East India Company and became part of the Madras Presidency. Eventually, this region emerged as the Coastal Andhra region. Later the Nizam rulers of Hyderabad ceded five territories to the British that eventually became the Rayalaseema region. The Nizams retained control of the interior provinces as the princely state of Hyderabad, acknowledging British rule in return for local autonomy. However, Komaram Bheem, a tribal leader, started his fight against the erstwhile Asaf Jahi Dynasty for the liberation of Hyderabad State. Meanwhile, the French occupied Yanam, in the Godavari delta, and (save for periods of British control) would hold it until 1954. In 1947, Vizianagaram was the largest Hindu princely state in Andhra Pradesh. In 1839 just before the British Raj, a cyclone struck Coringa, East Godavari district and toppled buildings, as a result 20,000 ships were destroyed and over 300,000 people were killed. India became independent from the British Raj in 1947. The 7th Nizam wanted to retain the independence of the Princely Hyderabad State from India, but the people of the region launched a movement to join the Indian Union. The state of Hyderabad was integrated into the Indian Union with Operation Polo in 1948. Post-independence In an effort to gain an independent state based on linguistic identity, and to protect the interests of the Telugu-speaking people of Madras State, Potti Sreeramulu fasted to death in 1952. As Madras became a bone of contention, in 1949 a JVP committee report stated: "Andhra Province could be formed provided the Andhras give up their claim on the city of Madras [now Chennai]". After Potti Sreeramulu's death, the Telugu-speaking area of Andhra State was carved out of Madras State on 1 October 1953, with Kurnool as its capital city. On the basis of the gentlemen's agreement of 1 November 1956, the States Reorganisation Act formed combined Andhra Pradesh by merging the Telugu-speaking areas of the already existing Hyderabad State. Hyderabad was made the capital of the new state. The Marathi-speaking areas of Hyderabad State merged with Bombay State and the Kannada-speaking areas were merged with Mysore
