Sir Surendranath Banerjee, often known as Rashtraguru, was an Indian nationalist leader during the British Raj. He founded the Indian National Association to bring Hindus and Muslims together for political action. He was also one of the founding members of the Indian National Congress. Unlike Congress, however, Surendranath supported Montagu–Chelmsford Reforms, and with many liberal leaders he left Congress and founded a new organisation, Indian National Liberation Federation, in 1919.
