The Charter Act of 1833 is historically significant for centralizing the British administration in India. One of its key provisions was redesignating the Governor-General of Bengal as the Governor-General of India. Lord William Bentinck, who was the Governor-General of Bengal at the time, became the first Governor-General of India under this Act.
This Act marked a shift from the East India Company’s role as a trading body with administrative functions to a purely administrative and political entity governing on behalf of the British Crown. It further consolidated British control over India.
The Regulating Act of 1773 created the post of Governor-General of Bengal. Pitt’s India Act of 1784 distinguished between the Company’s commercial and political activities and established the Board of Control. The Charter Act of 1793 extended the Company’s charter for 20 years.
