The Government of India Act of 1935 marked a milestone towards self-government in India. It provided for the establishment of an All-India Federation consisting of provinces and princely states. Power was divided between the Centre and provinces through three lists. However, the federation did not come into being as princely states did not join. The Act introduced dyarchy at the Centre and bicameral legislatures in six provinces. It extended communal representation and established institutions like the Reserve Bank of India and the Federal Court. The Act introduced responsible provincial governments in 1937 before being discontinued in 1939.
