Gandhi directly claimed authorship in 1940, while other sources either cite Nehru as a major editor or attribute it to Nehru outright . </P> <P> 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 . </P>
