Carnatic Wars

Background and the first two wars

The wars grew out of the rivalry between the British and French East India Companies for trade dominance in southern India, intertwined with wider European conflicts. The First Carnatic War (1746-48) coincided with the War of the Austrian Succession in Europe and saw the French, under Governor Joseph François Dupleix, capture the British settlement of Madras, which was returned under the terms of the Treaty of Aix-la-Chapelle. The Second Carnatic War (1749-54) was fought largely through proxy: both companies backed rival claimants to the thrones of the Carnatic and of Hyderabad, with the French supporting Chanda Sahib as Nawab of the Carnatic and the British backing Muhammad Ali Khan Wallajah. Robert Clive's seizure and successful defence of Arcot in 1751, undertaken with a small force to relieve pressure on Muhammad Ali's position at Trichinopoly, became the most celebrated episode of this phase and established Clive's reputation as a military commander.

The Third Carnatic War and outcome

The Third Carnatic War (1756-63) was fought as the Indian theatre of the global Seven Years' War between Britain and France. It culminated in the Battle of Wandiwash in January 1760, at which British forces under Eyre Coote decisively defeated the French army commanded by the Comte de Lally, followed by the fall of the French headquarters at Pondicherry in 1761. The Treaty of Paris in 1763 restored Pondicherry and other French settlements to France but stripped away French military and political influence in the region, permitting the French to remain only as unarmed traders.

Consequences

The wars established the East India Company, rather than its French counterpart, as the dominant European power in southern India and demonstrated the effectiveness of European-trained and led sepoy armies in Indian warfare, a model the Company subsequently extended elsewhere in the subcontinent. Muhammad Ali Khan Wallajah's confirmation as Nawab of the Carnatic left the Company as the decisive power behind the throne in the region, financially entangling the Nawab with the Company through large debts that later became a significant factor in Company politics. The wars are generally treated by historians as the opening phase of the Company's transformation from a trading concern into a territorial power in India, running in parallel with, and reinforcing, its rise to political dominance in Bengal following the Battle of Plassey in 1757.
