The Battle of Wandiwash, in 1760, established British supremacy over other European powers in India. It was the third major battle between the French and the British over the Carnatic region in South India.
The relationship between the French and the British worsened in 1740, when England and France took opposite sides in the War of Austrian succession. The first Carnatic War took place when the French laid siege to Madras, the chief British trading centre. On October 1748 after the conclusion of the War of Austrian Succession, Madras was restored to the English. On conclusion of the second Carnatic war, the British and French signed a treaty of non-interference.
In the third Carnatic war, in 1760, the British East India Company defeated the French forces in the Battle of Wandiwash. This win placed the British trading company in a far superior position in India which they retained for another two centuries.
