hello sagarnil ghosh

I hope you are doing good. I would glad to explain your query in easiet words i can:

At the time of Indian independence in 1947, India was divided into two sets of territories, one under direct British rule, and the other under the suzerainty of the British Crown, with control over their internal affairs remaining in the hands of their hereditary rulers. The latter included 562 princely states, having different types of revenue sharing arrangements with the British, often depending on their size, population and local conditions.  The political integration of these territories into India was a declared objective of the Indian National Congress, and the Government of India pursued this over the next decade.

Hope you found this answer helpful. Good luck for your future
