Under the Government of India Act 1919, partial responsible governance was established in the provinces. Subjects of provincial government were divided into two parts –
- Reserved subjects
- Transferred subjects.
The administrative operation of reserved subjects was done by the governor and his executive council. There was no control of legislature on them. The transferred subjects were handed over to the popular ministers who were selected by the elected members of legislature and who were responsible to them. In this way, dividing provincial governance into two parts was called Diarchy System.
