Jawaharlal Nehru became the youngest President of the Indian National Congress at its annual session in Lahore on 29 December, 1929. At that session, the Indian National Congress adopted the attainment of Poorna Swaraj as the immediate objective of India and the tricolor was unfurled on the banks of Ravi River.
