Constituent Assembly of India
C. Rajagopalachari was the one who took forward this demand of a Constituent Assembly on 15th November 1939, and his demand got accepted by the British in August 1940. The elections for the Constituent Assembly were held for the first time under the Cabinet Mission Plan of 1946. The Constituent Assembly drafted the Indian Constitution, which was also implemented under the same Cabinet Mission Plan on 16th May 1946.
The Muslim League was apparently not in favour of this assembly and boycotted the assembly after its failed attempts to stop its creation. The Constituent Assembly first met for the first time on 9th December 1946, and its last session was held on 24th January 1950.
