What did the government of india act introduced?

The Government of India Act 1935 was an Act of the Parliament of the United Kingdom.

Explanation:  It originally received Royal assent in August 1935 (25 & 26 Geo. 5 c. 42). Until 1999, it was the longest Act (British) of Parliament ever enacted. At that time, the Greater London Authority Act 1999 surpassed it in length. Because of its length, the Act was retroactively split by the Government of India Act, 1935 (Re-printed) (26 Geo. 5 & 1 Edw. 8 c. 1) into two separate Acts:

1. The Government of India Act, 1935 (26 Geo. 5 & 1 Edw. 8 c. 2), having 321 sections and 10 schedules.

2. The Government of Burma Act, 1935 (26 Geo. 5 & 1 Edw. 8 c. 3), having 159 sections and 6 schedules.

References in the literature on Indian political and constitutional history are usually to the shortened Government of India Act, 1935 (i.e. 26 Geo. 5 & 1 Edw. 8 c. 2), rather than to the text of the Act as originally enacted.
