The term 'British Sovereignty in India' refers to the period of British rule in India from 1858 to 1947. The RAJ, or Rajputana, was the name given to the British rule in India during this period. The RAJ was established after the Indian Rebellion of 1857, when the British East India Company was dissolved and the British Crown assumed direct control of the Indian subcontinent. During the RAJ, the British implemented a number of reforms, including the introduction of English as the official language, the establishment of a civil service, and the introduction of a modern legal system. The RAJ also saw the development of infrastructure, such as railways and telegraph lines, and the expansion of education and healthcare. The period of British rule in India ended with the independence of India in 1947.
