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.
Indian independence movement
The Indian self-rule movement was a mass-based movement that encompassed various sections of society. It also underwent a process of constant ideological evolution. Although the basic ideology of the movement was anti-colonial, it was supported by a vision of independent capitalist economic development coupled with a secular, democratic, republican, and civil-libertarian political structure. After the 1930s, the movement took on a strong socialist orientation, owing to the influence of Bhagat Singh's demand of Purna Swaraj (Complete Self-Rule). The work of these various movements led ultimately to the Indian Independence Act 1945, which ended the suzerainty in India and the creation of Pakistan. India remained a Dominion of the Crown until 26 January 1950, when the "Constitution of India" came into force, establishing the Republic of India; Pakistan was a dominion until 1956, when it adopted its first republican constitution. In 1971, East Pakistan declared independence as the People's Republic of Bangladesh.
