Lucknow Pact (Hindi: लखनऊ का मुआहिदा, Urdu: معاہدۂ لکھنؤ — Muʿāhidah-yi Lakhnaʾū; Urdu pronunciation: [ləkʰnəˌu kaː mʊˈaːɦɪd̪a]) 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 title of “the Ambassador of Hindu-Muslim Unity”.
As a result of the hard work of Mr. Jinnah and Mahajan from congresss , both the Muslim League and the Congress met for their annual sessions at Bombay in December 1915. The principal leaders of the two political parties assembled at one place for the first time in the history of these organizations. The speeches made from the platform of the two groups were similar in tone and theme. Within a few months of the Bombay meetings, 19 Muslim and Hindu elected members of the Imperial Legislative Council addressed a memorandum to the Viceroy on the subject of reforms in October 1916. Their suggestions did not become news in the British circle, but were discussed, amended and accepted at a subsequent meeting of the Congress and Muslim League leaders at Calcutta in November 1916. This meeting settled the details of an agreement about the composition of the legislatures and the quantum of representation to be allowed to the two communities. The agreement was confirmed by the annual sessions of the Congress and the League in their annual sessions held at Lucknow on December 29 and December 31, 1916 respectively. Sarojini Naidu gave Jinnah, the chief architect of the Lucknow Pact, the title of "the Ambassador of Hindu-Muslim Unity".
