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.
History of South India
On August 15, 1947, the former British India achieved independence as the new dominions of India and Pakistan. The rulers of India's princely states acceded to the government of India between 1947 and 1950, and South India was organized into a number of new states. Most of South India was included in Madras state, which included the territory of the former Madras Presidency together with the princely states of Banganapalle, Pudukkottai, and Sandur. The other states in South India were Coorg (the erstwhile Coorg province of British India), Mysore State (the former princely state of Mysore) and Travancore-Cochin, formed from the merger of the princely states of Travancore and Cochin. The former princely state of Hyderabad became Hyderabad State, and erstwhile Bombay Presidency became Bombay State.
