British Raj (rāj, lit. "reign" in Hindi) was the British rule in the Indian subcontinent between 1858 and 1947. The term can also refer to the period of dominion. The region under British control, commonly called India in contemporary usage, included areas directly administered by the United Kingdom (contemporaneously, "British India") as well as the princely states ruled by individual rulers under the paramountcy of the British Crown. After 1876, the resulting political union was officially called the Indian Empire and issued passports under that name. As India, it was a founding member of the League of Nations, and a member nation of the Summer Olympics in 1900, 1920, 1928, 1932, and 1936.

The system of governance was instituted in 1858, when the rule of the British East India Company was transferred to the Crown in the person of Queen Victoria (and who, in 1876, was proclaimed Empress of India), and lasted until 1947, when British India was partitioned into two sovereign dominion states, the Union of India (later the Republic of India) and the Dominion of Pakistan (later the Islamic Republic of Pakistan, the eastern half of which, still later, became the People's Republic of Bangladesh). The eastern-most part of the Indian Empire became the separate colony of Burma in 1937, and this gained independence in 1948.
