First session of the Indian National Congress was held in 1885

The first session of the Indian National Congress was held on 28 December 1885 in Bombay. The initial name of the organization was Indian National Union.

The Indian National Congress conducted its first session in Bombay from 28 to 31 December 1885 at the initiative of retired Civil Service officer Allan Octavian Hume. In 1883, Hume had outlined his idea for a body representing Indian interests in an open letter to graduates of the University of Calcutta. It aimed to obtain a greater share in government for educated Indians and to create a platform for civic and political dialogue between them and the British Raj. Hume took the initiative, and in March 1885 a notice convening the first meeting of the Indian National Union to be held in Poona the following December was issued. However due to a cholera outbreak there, it was moved to Bombay.

Hume organized the first meeting in Bombay with the approval of the Viceroy Lord Dufferin. Umesh Chandra Banerjee was the first president of Congress; the first session was attended by 72 delegates, representing each province of India. Notable representatives included Scottish ICS officer William Wedderburn, Dadabhai Naoroji, Pherozeshah Mehta of the Bombay Presidency Association, Ganesh Vasudeo Joshi of the Poona Sarvajanik Sabha, social reformer and newspaper editor Gopal Ganesh Agarkar, Justice K. T. Telang, N. G. Chandavarkar, Dinshaw Wacha, Behramji Malabari, journalist, and activist Gooty Kesava Pillai, and P. Rangaiah Naidu of the Madras Mahajana Sabha. This small elite group, unrepresentative of the Indian masses at the time, functioned more as a stage for elite Indian ambitions than a political party for the first decade of its existence.
