The Governor General of Bengal was designated as the Governor General of India by the Charter Act of 1833.

The Charter Act of 1833 was a significant legislation passed by the British Parliament that brought about important changes in the governance of British India. One of the key provisions of this act was the elevation of the Governor General of Bengal to the position of Governor General of India.

Prior to the Charter Act of 1833, the highest-ranking British official in India was known as the Governor General of Bengal. The Regulating Act of 1773 and the Pitts India Act of 1784 had established the office of the Governor General of Bengal to oversee the affairs of the British East India Company in Bengal.

However, as British control and influence expanded across India, there was a need for a more unified and centralized administration. The Charter Act of 1833 recognized this need and reorganized the governance structure of British India.

Under the act, the Governor General of Bengal was designated as the Governor General of India, with authority and jurisdiction extended beyond Bengal to encompass the entire British territories in the Indian subcontinent. This change reflected the growing scope of British rule in India and the increasing importance of a centralized authority to govern the vast territories.

The act also introduced other significant reforms, such as the separation of the legislative and executive functions, the establishment of a Law Commission, and the abolition of the East India Company's trade monopoly. These reforms aimed to improve the governance and administration of British India.

The designation of the Governor General of Bengal as the Governor General of India under the Charter Act of 1833 marked a crucial step in the evolution of British rule in India. It laid the foundation for a more unified and centralized administration and had far-reaching implications for the subsequent governance and political developments in colonial India.
