The Lahore session of the Indian National Congress, held in December 1929, was presided over by Jawaharlal Nehru. This session was significant for formally adopting the resolution for "Poorna Swaraj" (Complete Independence) from British rule. Key decisions made during this session included the declaration to celebrate January 26, 1930, as India's first Independence Day, and the authorization for the launch of the Civil Disobedience Movement. The historical importance of January 26 was later recognized when the Indian Constitution was adopted on this date in 1950.
