His (or Her) Majesty's Principal Secretary of State for India, known for short as the India Secretary or the Indian Secretary, was the British Cabinet minister and the political head of the India Office responsible for the governance of the British Indian Empire (usually known simply as 'the Raj' or British India), Aden, and Burma. The post was created in 1858 when the East India Company's rule in Bengal ended and India, except for the Princely States, was brought under the direct administration of the government in Whitehall in London, beginning the official colonial period under the British Empire.
