The Congress regularly observed 26 January as the Independence Day of India -- commemorating those who campaigned for Indian independence. In 1947, the British agreed to transfer power and political finesse to India, and 15 August became the official Independence Day. However, the new Constitution of India, as drafted and approved by the Constituent Assembly, was mandated to take effect on 26 January 1950, to commemorate the 1930 declaration. On that day in 1950, India became a republic. 26 January is now celebrated as Republic Day of India every year.
