Quick answer: The Anglo-French rivalry in India was fought through the three Carnatic Wars (1746-48, 1749-54, 1758-63), which ended with the Treaty of Paris (1763) and the Battle of Wandiwash (1760) where Eyre Coote defeated Count de Lally. The French lost because of British naval superiority, Bengal's wealth (after Plassey, 1757), poor support from France and weak leadership. The wars showed the English and French the value of training Indian soldiers (sepoys) and of interfering in the succession disputes of Indian rulers, the method that made the British the main power.

Dear students, here begins the story of the British takeover of India. Before Plassey and Buxar, there was a long contest between European companies on the Coromandel coast. The Prelims asks the dates, treaties and persons; the Mains asks "Why did the French fail in India?" I will give you a clean timeline, then the analysis.

European Companies Reach India

CompanyYearKey Points
Portuguese1498Vasco da Gama reached Calicut; Francisco de Almeida (policy of the "Blue Water"), Alfonso de Albuquerque (captured Goa in 1510, the real founder of Portuguese power); decline by the 17th century
Dutch (VOC)1602Settled at Masulipatnam, Pulicat, Surat, Cochin; mostly spice trade in the Indonesian islands; defeated by the English at Bedara (1759)

Danes1616Tranquebar, Serampore; sold their settlements to the English in 1845
French (Compagnie des Indes Orientales)1664Colbert, Louis XIV's minister; Pondicherry (1674, Francois Martin), Chandernagore (1690-92); Mahe, Karaikal, Yanam

Background to the Carnatic Wars

  • By the 1740s the Mughal control over the south had weakened. The Nizam of Hyderabad (Asaf Jah) ruled the Deccan and the Nawab of Arcot (Carnatic) was nominally under him.
  • The European war of the Austrian Succession (1740-48) broke out between Britain and France. It spread to India and the two companies began fighting for the control of trade and political influence.
  • The French governor-general Dupleix (1742-54) was a bold man who saw that a small European-led army trained in the European style could defeat much bigger Indian armies, and that by supporting claimants to the thrones he could control states.

The Three Carnatic Wars

WarYearsCause and EventsResult
First Carnatic War1746-1748Extension of the Austrian War of Succession. Labourdonnais (governor of Mauritius) captured Madras (1746) for the French. The Nawab of Carnatic, Anwaruddin, sent his army to protect the English, but was defeated at the Battle of St Thome (Adyar), 1746 by a small French force under Captain Paradis, which showed the European military superiorityTreaty of Aix-la-Chapelle (1748) ended the Austrian war; Madras was returned to the English
Second Carnatic War1749-1754Disputed succession in Hyderabad (Nasir Jang vs Muzaffar Jang) and the Carnatic (Anwaruddin vs Chanda Sahib). The French (Dupleix) supported Muzaffar Jang and Chanda Sahib; the English supported Nasir Jang and Muhammad Ali. Initially the French succeeded (Battle of Ambur, 1749; Muzaffar Jang became the Nizam; Bussy stayed at Hyderabad with the French forces). Robert Clive captured Arcot (1751) and held it against a siege of 53 days, which changed the course of the war. Chanda Sahib was killedDupleix was recalled by the French government (1754); the Treaty of Pondicherry (1755) between Godeheu and Saunders; both sides agreed not to interfere in the native disputes
Third Carnatic War1758-1763Seven Years' War in Europe. The French sent Count de Lally (1758), who captured Fort St David (1758) but failed against Madras (1758-59). The English naval power cut off French supplies. At Wandiwash (22 January 1760), Sir Eyre Coote defeated Lally and captured Bussy; Pondicherry surrendered (January 1761)The Treaty of Paris (1763) returned Pondicherry and Chandernagore to France but with limits (no fortification, no troops); the French ended their political ambitions in India; Lally was executed in Paris (1766)

Why Did the French Fail?

CauseExplanation
Naval weaknessThe British Royal Navy controlled the seas and cut the French supply lines. The French fleet under d'Ache was defeated and could not support Lally. Naval power decided the war
BengalAfter Plassey (1757) the English got the revenue of Bengal, the richest province, to pay for the war in the south; the French had no equivalent base and Chandernagore was lost (1757)
Company vs stateThe English company was a private trading firm that raised funds from shareholders and could act quickly; the French company depended on the king and the state, and its finances were weak and its orders slow
LeadershipThe English had a series of capable men (Clive, Stringer Lawrence, Eyre Coote, Admiral Watson). The French had Dupleix, Bussy and Lally, but Dupleix was recalled and Lally was hasty and unpopular, and quarrelled with Bussy and others
Priorities of FranceThe French government gave priority to its European wars and the colonies of North America and the Caribbean; the Indian trade was of less value
Local conditionsThe English had better financial resources and the control of three presidencies (Calcutta, Madras, Bombay), while the French support from the Nizam was limited after Bussy was withdrawn from Hyderabad

Lessons and Consequences

  • Military innovation: A small, disciplined force with muskets and artillery, trained on the European pattern, could defeat large Indian armies. Both companies recruited Indian sepoys and officered them, a model the British followed later.
  • Political method: Take sides in the succession fights and get territory or money in return. This was the origin of the later subsidiary alliance (see our upcoming notes on Wellesley).
  • The British primacy: After 1763, the British had no European rival in India, only the Indian powers: Bengal (Plassey 1757, Buxar 1764), Mysore, the Marathas and the Sikhs.

Chanda Sahib, Muhammad Ali, AnwaruddinClaimants and Nawabs of the Carnatic
Nasir Jang, Muzaffar JangClaimants to the Nizam's throne

Case Study: Arcot, 1751

Students, Clive was a young clerk-turned-officer when he convinced the Madras council to attack Arcot, the capital of Chanda Sahib, to draw his army away from Trichinopoly where the English ally Muhammad Ali was besieged. With about 200 Europeans and 300 sepoys, he took Arcot, which was lightly defended, and then held the fort against thousands of men of Chanda Sahib and French helpers for about 50 days. The fort held because of the discipline of the troops and the loyalty of the sepoys, and help from outside also arrived late in the siege. This victory raised the English prestige and taught Indian rulers that the English could not be ignored. The lesson in the answer is that small battles shaped the great political result.

Impact on the Indian Powers

Students, the Carnatic Wars changed more than the fortunes of two foreign companies. Three effects mattered for Indian history.

EffectExplanation
Exposure of Indian military weaknessAt St Thome a few hundred French soldiers beat an army many times larger. Indian rulers saw that cavalry charges and elephants were no match for disciplined musket and cannon fire
Rise of the sepoy armyBoth companies enrolled Indian soldiers, drilled them in European fashion and paid them regularly. This model later became the backbone of the British Indian Army, and also, in 1857, the source of its greatest crisis
Political bargaining by trading companiesThe companies realised that a throne could be bought with military help. The Nizam, the Nawab of Arcot and later the Nawab of Bengal were all drawn into this game
Beginning of the Company-stateTerritorial and revenue grants from allied rulers (for example the Northern Circars, first held by the French and later passing to the English) turned traders into rulers

Timeline for Quick Revision

YearEvent
1664French East India Company founded
1674Pondicherry founded
1742Dupleix becomes governor-general
1746Fall of Madras; Battle of St Thome
1748Treaty of Aix-la-Chapelle
1751Clive takes and holds Arcot
1755Treaty of Pondicherry
1757Plassey; French lose Chandernagore
1760Wandiwash
1761Pondicherry surrenders
1763Treaty of Paris

Teacher's note: when you answer on "foundations of British rule", start with the Carnatic Wars (military model), go to Plassey (resources), end with Buxar and the Diwani of 1765 (legal authority). This three-step chain is easy to remember and shows the examiner a causal flow.

Common Mistakes Students Make

  • Confusing Wandiwash (1760, English victory) with Plassey (1757) or Buxar (1764).
  • Writing that the Treaty of Paris (1763) ended the French in India. The French stayed in Pondicherry, Chandernagore, Mahe, Karaikal and Yanam until 1954-62, but without political power.
  • Believing that Dupleix lost because of weak strategy. He was recalled by his government, which had grown tired of the cost.
  • Mixing the Carnatic Wars with the Anglo-Mysore Wars.

Teacher's Tip

Students, memorise the sequence of treaties: Aix-la-Chapelle (1748) - Pondicherry (1755) - Paris (1763), and the key persons for each war: Paradis/Labourdonnais - Clive/Dupleix - Coote/Lally. For the Mains, a three-heading answer works: naval power, financial resources (Bengal) and quality of leadership/government support.

Important Points for the Exam

  • Carnatic Wars: 1746-48, 1749-54, 1758-63; treaties of 1748, 1755 and 1763.
  • Arcot (1751, Clive), Wandiwash (1760, Coote vs Lally), Pondicherry fell 1761.
  • French reasons for failure: sea power, Bengal wealth, government neglect.
