Why was the formation of the Indian National Congress a landmark in Indian history?

The Indian National Congress was founded in 1885. It was the result of the effort of a number of educated Indians who were highly discontented with the exploitative nature of the British rule. In the beginning, its objective was to get a bigger share in government for enlightened Indians.

 Inspired by A.O. Hume, a retired British civil servant, seventy three delegates met in Bombay for the first time. The first president of the Indian National Congress, or INC, was W. C. Banerjee. As time passed, the nature of the INC changed, and it became very active in the movement for Indian independence.

 After independence, the Congress, which was till then a national movement, became a political party.
