The Government of India Act of 1919 divided the functions of government into central and provincial. The provincial subjects were further subdivided into transferred and reserved. Thus, in the provinces a new form of government, dyarchy, was introduced. Dyarchy means dual set of governments — accountable and non-accountable. In the transferred subjects the Governors were assisted by ministers responsible to the legislature, while in the reserved subjects the Governors were advised by councillors not accountable to the legislature.
