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 (Pakistan)
In 1946, the Labour government in Britain, exhausted by recent events such as World War II and numerous riots, realized that it had neither the mandate at home, the support internationally, nor the reliability of the British Indian Army for continuing to control an increasingly restless British India. The reliability of the native forces for continuing their control over an increasingly rebellious India diminished, and so the government decided to end the British rule of the Indian Subcontinent. In 1946, the Indian National Congress, being a secular party, demanded a single state. The Muslim majorities, who disagreed with the idea of single state, stressed the idea of a separate Pakistan as an alternative. The 1946 Cabinet Mission to India was sent to try to reach a compromise between Congress and the Muslim League, proposing a decentralized state with much power given to local governments, but it was rejected by both of the parties and resulted in a number of riots in South Asia.
