In 1929, the Indian National Congress held a significant session in Lahore, presided over by Jawaharlal Nehru. This session is historical for passing the 'Purna Swaraj' (complete independence) resolution on December 19, advocating for India's absolute freedom from British rule. The resolution, introduced by Nehru and seconded by Vallabhbhai Patel, set a groundbreaking path toward establishing a sovereign republic. Following this resolution, January 26, 1930, was declared as Independence Day by the Congress, which was celebrated for the next 17 years as a symbol of India's struggle for independence. During this session, the tricolor flag was hoisted by Nehru on the banks of the Ravi River, embodying the nation's aspirations for complete self-rule. This session marked a pivotal turn in India's freedom movement, echoing the demand for Purna Swaraj and leading to the initiation of a Civil Disobedience Movement under Mahatma Gandhi’s leadership.
