Lucknow Pact refers to an agreement reached between the Indian National Congress and the Muslim League at the joint session of both the parties, held in Lucknow, in the year 1916. Muhammad Ali Jinnah, then a member of the Congress as well as the League, made both the parties reach an agreement to pressure the British government to adopt a more liberal approach to India and give Indians more authority to run their country, besides safeguarding basic Muslim demands. After the unpopular partition of Bengal, Jinnah approached the League to make it more popular among the Muslim masses. Jinnah himself was the mastermind and architect of this pact. Due to the reconciliation brought about by Jinnah between the Congress and the League, the Nightingale of India, Sarojini Naidu, gave him the titile of “the Ambassador of Hindu-Muslim Unity”.The Lucknow Pact also established cordial relations between the two prominent groups of the Indian National Congress – the "hot faction" garam dal led by Bal Gangadhar Tilak, and the moderates or the "soft faction", the naram dal led by Gopal Krishna Gokhale.
