However, a large part called Marathwada remained part of the Nizam's Hyderabad State throughout the British period. The period of British rule was marked by social reforms and an improvement in infrastructure as well as revolts due to their discriminatory policies. At the turn of the 20th century, the struggle for independence took shape, led by radical nationalist Bal Gangadhar Tilak and the moderates like Justice Mahadev Govind Ranade, Gopal Krishna Gokhale, Pherozeshah Mehta and Chhatrapati Shahu Maharaj, Dadabhai Naoroji, Dr. B. R. Ambedkar, Jyotirao Phule – social reformers who were all born in this region. After the partial autonomy given to the states by the Government of India Act 1935, B. G. Kher became the first Chief Minister of the Congress party-led Government of tri-lingual Bombay Presidency. The ultimatum to the British during the Quit India Movement was given in Mumbai, and culminated in the transfer of power and independence in 1947. After India's independence, the Deccan States, including Kolhapur were integrated into Bombay State, which was created from the former Bombay Presidency in 1950. In 1956, the States Reorganisation Act reorganised the Indian states along linguistic lines, and Bombay Presidency State was enlarged by the addition of the predominantly Marathi-speaking regions of Marathwada (Aurangabad Division) from erstwhile Hyderabad state and Vidarbha region from the Central Provinces and Berar. The southernmost part of Bombay State was ceded to Mysore. From 1954 to 1955 the people of Maharashtra strongly protested against bilingual Bombay state and Samyukta Maharashtra Samiti, was formed. The Mahagujarat Movement was started, seeking a separate Gujarat state. Keshavrao Jedhe, S.M. Joshi, Shripad Amrit Dange, Pralhad Keshav Atre and Gopalrao Khedkar fought for a separate state of Maharashtra with Mumbai as its capital under the banner of Samyukta Maharashtra Movement. On 1 May 1960, following mass protests and 105 deaths, the separate Marathi-speaking state was formed by dividing earlier Bombay State into the new states of Maharashtra and Gujarat. The state continues to have a dispute with Karnataka regarding the region of Belgaum and Karwar. Maharashtra occupies the western and central part of the country and has a long coastline stretching 720 kilometres along the Arabian Sea.
