Dupleix was named the Governor General of French regions in India in 1742. He dreamt of achieving French harmony over India and entered into treaties with the local kings. Hyder Ali was also trained in the army of locals raised by Dupleix.
The British considered Dupleix as a formidable challenge to them. Hence, we notice clashes over between the French and the British to gain supremacy over Carnatic and Deccan Plateau.
Dupleix played an important role in the First Carnatic War in 1746. The rivalry between the French and the British continued till 1754. Later, French government recalled Dupleix as it wanted peace.
