The term 'British Administration' refers to the period of British rule in India, which lasted from 1858 to 1947. The RAJ, or British RAJ, was the period of direct British rule over the Indian subcontinent. During this period, the British government had complete control over the Indian economy, politics, and society. The British RAJ was characterized by a strong central government, with a bureaucracy that was largely staffed by British officials. This period saw the introduction of many reforms, such as the establishment of a modern legal system, the introduction of English as the official language, and the development of infrastructure.
