The India Office was a British government department created in 1858 to oversee the administration, through a Viceroy and other officials, of the Provinces of British India. These territories comprised most of the modern-day nations of Bangladesh, Burma, India, and Pakistan, as well as Aden and other territories around the Indian Ocean. The department was headed by the Secretary of State for India, a member of the British cabinet, who was formally advised by the Council of India.
