Republic Day
India gained its independence on 15 August 1947, after which the process of preparing a constitution was started. The Constitution was passed on 26 November 1949 in the Constituent Assembly. It was adopted on 26 January 1950 with a democratic government system. 26 January was selected, because it was this day in 1930 when the Declaration of Indian Independence was passed.
India achieved independence from British rule on 15 August 1947 following the Indian independence movement noted for largely peaceful nonviolent resistance and civil disobedience led by the Indian National Congress. 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 of coming into force of its constitution.
Independence Day (India)
The new viceroy, Lord Mountbatten, advanced the date for the transfer of power, believing the continuous contention between the Congress and the Muslim League might lead to a collapse of the interim government. He chose the second anniversary of Japan's surrender in World War II, 15 August, as the date of power transfer. The British government announced on 3 June 1947 that it had accepted the idea of partitioning British India into two states; the successor governments would be given dominion status and would have an implicit right to secede from the British Commonwealth. The Indian Independence Act 1947 (10 & 11 Geo 6 c. 30) of the Parliament of the United Kingdom partitioned British India into the two new independent dominions of India and Pakistan (including what is now Bangladesh) with effect from 15 August 1947, and granted complete legislative authority upon the respective constituent assemblies of the new countries. The Act received royal assent on 18 July 1947.
