Explanation:

Wellesley came to India with a determination to launch a forward policy in order to make ‘the British Empire in India’ into ‘the British Empire of India’.The system that he adopted to achieve his object is known as the ‘Subsidiary Alliance’.Moreover, the policy of neutrality adopted by Sir John Shore, the successor of Cornwallis,created a kind of political unrest in India and greatly affected the prestige of the English.His non-intervention policy contributed much to the growth of anti-British feelings. Further,Napoleon’s move for an Eastern invasion created a fear among English statesmen.It was in this light that Wellesley moulded his policy. Preservation of British prestige and removal of French danger from India were Wellesley’s twin aims.
