Political integration of India

Before it gained independence in 1947, India (also called the Indian Empire) was divided into two sets of territories, one under direct British rule (British India), and the other consisting of princely states under the suzerainty of the British Crown, with control over their internal affairs remaining to varying degrees in the hands of their hereditary rulers. The latter included 562 princely states which had different types of revenue-sharing arrangements with the British, often depending on their size, population and local conditions.
