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.

The partition of India was set forth in the Indian Independence Act 1947 and resulted in the dissolution of the British Indian Empire and the end of the British Raj. It resulted in a struggle between the newly constituted states of India and Pakistan and displaced up to 12.5 million people with estimates of loss of life varying from several hundred thousand to a million (most estimates of the numbers of people who crossed the boundaries between India and Pakistan in 1947 range between 10 and 12 million). The violent nature of the partition created an atmosphere of mutual hostility and suspicion between India and Pakistan that plagues their relationship to this day.
The partition included the geographical division of the Bengal province into East Bengal, which became part of the Dominion of Pakistan (from 1956, East Pakistan). West Bengal became part of India, and a similar partition of the Punjab province became West Punjab (later the Pakistani Punjab and Islamabad Capital Territory) and East Punjab (later the Indian Punjab, as well as Haryana and Himachal Pradesh). The partition agreement also included the division of Indian government assets, including the Indian Civil Service, the Indian Army, the Royal Indian Navy, the Indian railways and the central treasury, and other administrative services.
