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)
The Indian Independence Act 1947 (10 & 11 Geo 6 c. 30) passed by the Parliament of the United Kingdom divided British India into the two new independent dominions; the Dominion of India (later to become the Republic of India) and the Dominion of Pakistan (later to become the Islamic Republic of Pakistan). The act provided a mechanism for division of the Bengal and Punjab provinces between the two nations (see partition of India), establishment of the office of the Governor-General, conferral of complete legislative authority upon the respective Constituent Assemblies, and division of joint property between the two new countries. The act later received royal assent on 18 July 1947. The partition was accompanied by violent riots and mass casualties, and the displacement of nearly 15 million people due to religious violence across the subcontinent; millions of Muslim, Sikh and Hindu refugees trekked the newly drawn borders to Pakistan and India respectively in the months surrounding independence. On 14 August 1947, the new Dominion of Pakistan became independent and Muhammad Ali Jinnah was sworn in as its first governor general in Karachi. Independence was marked with widespread celebration, but the atmosphere remained heated given the communal riots prevalent during independence in 1947.
