The British Raj was a former country in what is now known as Hindustan. It is a time of British-Indian rule from 1833 to 1861 until the Sepoy Revolution. British control there was originated by the British East India Co., which was a major controller of the trade monopoly in India. After the conquest of Britain by Napoleon in 1823, most members of the British government as well as refugees from the former country settled in India. At first, they were considered a separate country from the rest of India. However, after 1833, British Raj began the conquest of the Indian subcontinent. Although they used mostly war to control India, they used diplomacy as well to get Indian states to join the British Raj. By 1851, the last independent Indian kingdom fell to the British Raj.
