After the decline of the Mughal Empire, the English East India Company (EIC) transitioned from a trading body to a political power. Through a combination of military victories, diplomacy, alliance-making, and annexation policies, the Company established hegemony over large parts of the Indian subcontinent.
I. The Conquest of Bengal #
Bengal was the richest province in India. Its conquest provided the EIC with the revenue base needed to fund further expansions.
| Event | Year | Parties | Result / Importance |
|---|---|---|---|
| Fortification dispute | 1756 | Siraj-ud-Daulah vs British | Siraj objected to unauthorized British fortification of Calcutta and misuse of trade privileges. |
| Black Hole Tragedy | 1756 | Siraj-ud-Daulah vs British | Alleged incident used by the British as a pretext for war. |
| Treaty of Alinagar | Feb 1757 | Siraj-ud-Daulah & Robert Clive | Restored British privileges; acted as a prelude to Plassey. |
| Battle of Plassey | 23 June 1757 | Robert Clive vs Siraj-ud-Daulah | Mir Jafar defected; British victory laid the foundation of British rule. |
| Mir Qasim’s reforms | 1760-1763 | Mir Qasim vs Company officials | Shifted capital to Munger, reorganized army, and abolished internal duties to challenge Company misuse of dastaks. |
| Battle of Buxar | 22 Oct 1764 | Hector Munro vs Mir Qasim, Shuja-ud-Daulah, Shah Alam II | Decisive British victory; established the EIC as a de facto ruler in North India. |
| Treaty of Allahabad | 1765 | Robert Clive, Shah Alam II, Shuja-ud-Daulah | EIC secured Diwani Rights for Bengal, Bihar, and Odisha. |
| Dual System | 1765-1772 | Robert Clive | Company held the Diwani (revenue), while the Nawab held the Nizamat (administration). Abolished by Warren Hastings. |
Aftermath of Bengal Conquest #
- Plassey was a political victory, won more by conspiracy and betrayal than by battlefield superiority.
- Buxar was a military victory, and is considered more decisive because the British defeated three major powers together.
- Bengal’s revenue financed Company wars in Mysore, Maratha territory, and other regions.
- The Dual System caused administrative breakdown because power and responsibility were separated.
- The Bengal Famine of 1770 exposed the exploitative nature of Company revenue policies.
II. Carnatic Wars: End of French Challenge #
The Carnatic Wars were fought in South India as part of the wider Anglo-French rivalry. They prepared the ground for British political expansion.
| War | Period | Key Treaty / Event | Importance |
|---|---|---|---|
| First Carnatic War | 1746-1748 | Treaty of Aix-la-Chapelle (1748) | Madras was restored to the British; showed European wars could affect India. |
| Second Carnatic War | 1749-1754 | Treaty of Pondicherry (1754) | Dupleix’s Indian ambitions failed; British influence rose through Muhammad Ali. |
| Third Carnatic War | 1756-1763 | Battle of Wandiwash (1760), Treaty of Paris (1763) | French political influence in India ended; they retained only trading settlements. |
III. Expansion in the South: Anglo-Mysore Wars #
Mysore, under Haider Ali and Tipu Sultan, was a formidable obstacle to British expansion in Southern India.
| War | Period | Treaty | Outcome |
|---|---|---|---|
| First Anglo-Mysore War | 1767-1769 | Treaty of Madras (1769) | Haider Ali defeated the British; treaty promised mutual restoration of conquests and defensive aid. |

| Second Anglo-Mysore War | 1780-1784 | Treaty of Mangalore (1784) | Haider Ali died (1782); Tipu continued the war; treaty restored conquered territories. |
| Third Anglo-Mysore War | 1790-1792 | Treaty of Seringapatam (1792) | Tipu lost half his territory and paid heavy indemnity; two sons were taken as hostages. |
| Fourth Anglo-Mysore War | 1799 | No Treaty | Tipu Sultan died defending Seringapatam; Mysore came under Subsidiary Alliance. |
Why Mysore Was Important #
- Haider Ali modernized the Mysore army and used French military support.
- Tipu Sultan was called the “Tiger of Mysore” and promoted state-controlled trade, coinage reforms, and military modernization.
- Tipu sent diplomatic missions to France, Turkey, and Afghanistan to seek help against the British.
- After 1799, the Wodeyar dynasty was restored under British control, while parts of Mysore were shared among the British, Nizam, and Marathas.
IV. Subjugation of the Marathas #
The Maratha Confederacy was the most powerful Indian power after the Mughals, but internal divisions led to its downfall.
| War / Event | Period | Key Treaty | Result |
|---|---|---|---|

| Convention of Wadgaon | 1779 | British & Marathas | British were forced to surrender after defeat near Pune; later rejected by Warren Hastings. |
| Treaty of Bassein | 1802 | Peshwa Baji Rao II & British | Peshwa accepted Subsidiary Alliance; major blow to Maratha independence. |
| Second Anglo-Maratha War | 1803-1805 | Bassein (1802), Deogaon (1803), Surji-Anjangaon (1803) | Maratha power weakened; British influence expanded in central and northern India. |

Causes of Maratha Decline #
- Lack of unity among the Peshwa, Scindia, Holkar, Bhonsle, and Gaekwad.
- Defeat at the Third Battle of Panipat (1761) weakened Maratha prestige.
- Treaty of Bassein is often treated as a turning point because it placed the Peshwa under British protection.
- After 1818, Baji Rao II was pensioned off to Bithur, and the small kingdom of Satara was created for Pratap Singh.
V. Conquest of the North-West: Punjab & Sindh #
| War / Event | Period | Key Person / Treaty | Result |

| Treaty of Amritsar | 1809 | Ranjit Singh & Charles Metcalfe | Fixed the Sutlej as boundary of Sikh expansion; British accepted Ranjit Singh’s control west of the Sutlej. |

VII. Tools of Expansion: Diplomatic Policies #
The British used military pressure, treaties, and administrative doctrines to annex or control Indian states.
1. Subsidiary Alliance (Lord Wellesley, 1798) #
The Indian ruler had to maintain a British force in their territory and pay for it. They also had to station a British Resident at their court.
- The ruler could not employ Europeans or enter alliances/war without British permission.
- If the ruler could not pay for the subsidiary force, territory was ceded to the Company.
- It weakened Indian states financially and militarily while preserving nominal sovereignty.
- Order of Acceptance:
- Hyderabad (1798) - First to accept.
- Mysore (1799)
- Tanjore (1799)
- Awadh (1801)
- Peshwa (1802)
- Bhonsle (1803)
- Scindia (1804)
2. Doctrine of Lapse (Lord Dalhousie, 1848) #
If an Indian ruler of a dependent state died without a natural heir, the state was annexed by the British. Adopted sons were not recognized as heirs to the throne.
- Annexations under Doctrine of Lapse:
- Satara (1848) - First to be annexed.
- Jaitpur & Sambalpur (1849)
- Baghat (1850)
- Udaipur (1852)
- Jhansi (1853)
- Nagpur (1854)
Note: Awadh (1856) was annexed on grounds of “Maladministration”, not the Doctrine of Lapse.
3. Other Expansionist Methods #
- Ring Fence Policy: Associated with Warren Hastings; aimed to defend Company territories by surrounding them with buffer states.
- Forward Policy: Aggressive frontier policy used especially in the north-west to check Russian/Afghan influence.
- Policy of Subordinate Isolation: Indian states accepted British protection but were isolated from each other.
- Policy of Subordinate Union: After 1857, princely states were treated as subordinate allies of the Crown rather than targets for annexation.
