The demand that India’s constitutional future must be shaped by an elected constituent assembly of Indians without British imperial dictation was a cardinal demand of the Indian National Movement. The historical evolution unfolded through several critical stages:
| Year | Milestone / Proponent | Historical Significance |
|---|---|---|
| 1934 | M.N. Roy | Pioneering communist thinker M.N. Roy first put forward the explicit idea of a Constituent Assembly for India. |
| 1935 | Indian National Congress (INC) | The INC officially demanded a Constituent Assembly to frame the Constitution of free India. |
| 1938 | Jawaharlal Nehru | Declared on behalf of the INC that the Constitution of free India must be framed without outside interference by a Constituent Assembly elected on adult franchise. |
| 1940 | August Offer | The British Government for the first time conceded in principle that framing a new constitution was primarily the responsibility of Indians themselves. |
| 1942 | Cripps Mission | Sir Stafford Cripps brought a draft proposal for an independent constitution after World War II, but was rejected by both INC and Muslim League. |
| 1946 | Cabinet Mission Plan | Comprising Lord Pethick-Lawrence, Sir Stafford Cripps, and A.V. Alexander. Rejected two separate assemblies and formulated the actual blueprint under which the Constituent Assembly was constituted. |
