India achieved independence from British rule on 15 August 1947 following the Indian independence movement noted for largely peaceful non-violent resistance and civil disobedience led by Mahatma Gandhi. The independence came through the Indian Independence Act 1947 (10 & 11 Geo 6 c 30), an Act of the Parliament of the United Kingdom that partitioned British India into the two new independent Dominions of the British Commonwealth (later Commonwealth of Nations): India and Pakistan. India obtained its independence on 15 August 1947 as a constitutional monarchy with George VI as head of state and the Earl Mountbatten as governor-general. The country, though, did not yet have a permanent constitution; instead its laws were based on the modified colonial Government of India Act 1935. On 28 August 1947, the Drafting Committee was appointed to draft a permanent constitution, with Dr B R Ambedkar as chairman. While India’s Independence Day celebrates its freedom from British Rule, the Republic Day celebrates the coming into force of its constitution. A draft constitution was prepared by the committee and submitted to the Assembly on 4 November 1947. The Assembly met, in sessions open to public, for 166 days, spread over a period of 2 years, 11 months and 18 days before adopting the Constitution. After many deliberations and some modifications, the 308 members of the Assembly signed two hand-written copies of the document (one each in Hindi and English) on 24 January 1950. Two days later, it came into effect throughout the whole nation.
