The Indian National Congress (INC), a voice of Indian opinion to the British government held its first session on 28th December, 1885. From its foundation on 28th December 1885 until the time of independence of India on 15 August 1947, the Indian National Congress (INC) was considered to be the largest and most prominent Indian public organization, and central and defining influence of the Indian Independence Movement.
Founded upon the authority of British civil servant Allan Octavian Hume, the Congress was created to form a platform for civic and political dialogue of educated Indians with the British Raj and met each December. The first meeting was scheduled to be held in Poona, but due to a cholera outbreak it was shifted to Bombay. Womesh Chandra Bonnerjee was the first president of the Congress; the first session was held from 28–31 December 1885, and was attended by 72 delegates.
From the late 19th-century, and especially after 1920, under the leadership of Mahatma Gandhi, the Congress became the principal leader of the Indian independence movement, with over 15 million members and over 70 million participants. The Congress led India to independence from Great Britain, and powerfully influenced other anti-colonial nationalist movements in the British Empire.
