The provinces of India, earlier presidencies of British India and still earlier, presidency towns, were the administrative divisions of British governance on the Indian subcontinent. Collectively, they have been called British India. In one form or another, they existed between 1612 and 1947, conventionally divided into three historical periods:
"British India" did not include the many princely states which continued to be ruled by Indian princes, though by the 19th century under British suzerainty—their defence, foreign relations, and communications relinquished to British authority and their internal rule closely monitored. At the time of Indian Independence, in 1947, there were officially 565 princely states, a few being very large although most were very small. They comprised a quarter of the population of the British Raj and two fifths of its land area, with the provinces comprising the remainders.
