The Dyarchy system was introduced in the Government of India Act of 1919. The act aimed to increase Indian participation in the governance of British India and was a major step towards Indian self-government.
Under the Dyarchy system, certain administrative functions were transferred from the British Indian government to the Indian-run provincial governments. The transferred functions included subjects such as education, public health, and agriculture, while subjects such as defense, foreign affairs, and finance remained under British control.
However, the Dyarchy system was criticized for its complex and confusing nature, and it was soon replaced by other reforms aimed at further increasing Indian participation in governance. The Dyarchy system played an important role in the development of India’s democratic system, and it remains an important part of India’s political history.
