🇮🇳Happy Republic Day🇮🇳. By :-Rahil. ❤😇 फिल्म का नाम है पूरब पश्चिम. The Constitution was adopted by the Indian Constituent Assembly on 26 November 1949 and came into effect on 26 January 1950 with a democratic government system, completing the country's transition towards becoming an independent republic. 26 January was chosen as the date for Republic day because it was on this day in 1929 when the Declaration of Indian Independence (Purna Swaraj) was proclaimed by the Indian National Congress as opposed to the Dominion status offered by the British Regime.
