Following the Indian Rebellion of 1857, the East India Company's remaining powers were transferred to the British Crown in the person of Queen Victoria (who in 1876 was proclaimed Empress of India). As a state, the British Raj functioned as the guardian of a system of connected markets maintained by military power, business legislation and monetary management. The Government of India Act 1858 saw the India Office of the British government assume the administration of British India through a Viceroy appointed by the Crown.
