Solution:
Lord Wellesley introduced the subsidiary alliance system in India. The subsidiary Alliance System was essentially a treaty signed by the British East India Company and the rulers of India. As a result, the Indian kingdoms that agreed to sign the Subsidiary Alliance ceded sovereignty to the English. The native Indian took Subsidiary Alliance with the British and was forced to disband his armed forces to accept British forces in his territory. He also had to pay for the British army's upkeep. If he failed to make payment, then a portion of the territory would be taken.
