The Government of India Act, 1919 (also known as the Montagu-Chelmsford Reforms) introduced the system of ‘Dyarchy’ in the provinces.
Dyarchy involved dividing provincial subjects into two lists: ‘reserved’ subjects (administered by the Governor and his Executive Council without responsibility to the legislature) and ‘transferred’ subjects (administered by the Governor on the advice of ministers responsible to the legislative council).
The main aim of Dyarchy was to gradually introduce a responsible government in the provinces. However, it faced several difficulties in implementation and was eventually abolished by the Government of India Act, 1935, which introduced provincial autonomy.
