British Conquest & Expansion
British Conquest & Expansion in India
The British conquest of India was a gradual process spanning over a century (1757-1857). Starting with the Battle of Plassey, the East India Company used a combination of military force, diplomatic cunning, and administrative policies like Subsidiary Alliance and Doctrine of Lapse to bring the entire Indian subcontinent under its control.
Key Dates

Battle of Plassey (1757)
The Battle of Plassey was fought on 23 June 1757 between the forces of the East India Company led by Robert Clive and the Nawab of Bengal, Siraj-ud-Daulah. The real cause was the Company's abuse of trade privileges (dastak) and fortification of Calcutta without permission. The battle was won through conspiracy — Mir Jafar (Siraj's commander-in-chief), Rai Durlabh, Jagat Seth, and Omichand betrayed the Nawab. Siraj was killed, and Mir Jafar was installed as the puppet Nawab. Plassey was more of a 'transaction' than a battle — it established British political control over Bengal and gave them enormous wealth.
Battle of Buxar (1764)
The Battle of Buxar (22 October 1764) was fought between the British under Major Hector Munro and the combined forces of Mir Qasim (deposed Nawab of Bengal), Shuja-ud-Daulah (Nawab of Awadh), and Shah Alam II (Mughal Emperor). Mir Qasim had been installed as Nawab after Mir Jafar was deposed but turned hostile when he tried to abolish the Company's trade privileges. Buxar was far more militarily significant than Plassey — it established the Company as an unrivalled military power in northern India. The subsequent Treaty of Allahabad (1765) gave the Company Diwani rights over Bengal, Bihar, and Orissa.
Subsidiary Alliance System
Introduced by Lord Wellesley (Governor-General, 1798-1805), the Subsidiary Alliance system required Indian rulers to maintain a British Resident at their courts, accept a British subsidiary force for 'protection,' pay for the maintenance of this force (or cede territory in lieu), and surrender control of their foreign affairs. In return, the British promised protection from external aggression. States that accepted: Hyderabad (1798, first to accept), Mysore (1799), Tanjore (1799), Awadh (1801), Peshwa (1802, Treaty of Bassein), Sindhia (1804), Jodhpur, Jaipur, Macheri, Bundi, and Bharatpur. This system was a masterstroke — it disarmed Indian states, isolated them diplomatically, and made them financially dependent on the British without the need for direct conquest.
Doctrine of Lapse
The Doctrine of Lapse was an annexation policy devised and most aggressively applied by Lord Dalhousie (Governor-General, 1848-56). Under this policy, if an Indian ruler died without a natural male heir, his adopted heir would not be recognized, and the kingdom would be annexed by the British. States annexed under this doctrine: Satara (1848), Sambalpur (1850), Udaipur (1852), Nagpur (1854), Jhansi (1853), and Baghat, Jaitpur, and other smaller states. Dalhousie also annexed Awadh (1856) on grounds of 'misgovernance' and Punjab (1849) by right of conquest. This policy caused widespread resentment and was one of the major causes of the Revolt of 1857.
Anglo-Mysore Wars
Four wars (1767-99) were fought between the British and Mysore under Hyder Ali and Tipu Sultan. First Anglo-Mysore War (1767-69): Hyder Ali defeated the British; Treaty of Madras (1769) was humiliating for the British. Second Anglo-Mysore War (1780-84): Hyder Ali initially won (Battle of Pollilur, 1780) but died in 1782; Tipu Sultan continued and signed the Treaty of Mangalore (1784) — the last occasion when an Indian power dictated terms to the British. Third Anglo-Mysore War (1790-92): Tipu defeated; Treaty of Srirangapatnam — Tipu ceded half his territories and paid a heavy indemnity, sending his two sons as hostages. Fourth Anglo-Mysore War (1799): Tipu killed defending Srirangapatnam; Mysore restored to the Wadiyar dynasty under British suzerainty.
Anglo-Sikh Wars
Two wars were fought between the British and the Sikh Empire after Ranjit Singh's death (1839). First Anglo-Sikh War (1845-46): Fought due to internal dissension in the Sikh army (Khalsa) and British expansionism. Key battles: Mudki, Ferozeshah, Aliwal, and Sobraon. Treaty of Lahore (1846) — Sikhs ceded Jalandhar Doab and accepted a British Resident. Treaty of Bhyrowal (1846) — a Council of Regency was set up under British supervision. Second Anglo-Sikh War (1848-49): Started with the revolt of Mulraj at Multan. Key battles: Chilianwala and Gujarat. Lord Dalhousie annexed Punjab entirely in 1849, and the Koh-i-Noor diamond was surrendered to the British Crown.
The Dual System and Plunder of Bengal (1765-1772)
After the Battle of Buxar and the Treaty of Allahabad (1765), Clive established the 'Dual System' or 'Double Government' in Bengal. Under this system, the Company held the Diwani (revenue collection rights) while the Nawab retained the Nizamat (criminal jurisdiction and civil administration). In practice, the Company collected enormous revenues while taking no responsibility for governance, justice, or welfare. The Nawab had responsibility but no resources. This arrangement led to catastrophic consequences: revenue was extracted ruthlessly by Company servants and their Indian agents, no investments were made in infrastructure or famine relief, corruption was rampant (Company servants engaged in private trade using their tax-exempt status), and Bengal was systematically plundered. The Bengal Famine of 1770, which killed approximately 10 million people (one-third of the population), occurred under this system — the Company continued to collect revenue even as people starved. Warren Hastings (Governor-General 1773-1785) abolished the Dual System in 1772, taking over direct administration, but the economic damage had been done. The phrase 'Plunder of Bengal' was used by Edmund Burke during the impeachment trial of Warren Hastings (1788-95) in the British Parliament.
Warren Hastings — Administration and Controversies
Warren Hastings (Governor-General 1773-1785) was the first Governor-General of Bengal under the Regulating Act. He abolished the Dual System and assumed direct responsibility for revenue collection and administration. Key contributions: established the Board of Revenue at Calcutta, reformed the judicial system (Diwani Adalat for civil cases, Faujdari Adalat for criminal cases), appointed Indian judges (qazis and muftis), commissioned the first English translation of the Bhagavad Gita (by Charles Wilkins, 1785), and founded the Asiatic Society of Bengal (1784, through his support of William Jones). Controversies: the Rohilla War (1774 — Hastings hired out Company troops to the Nawab of Awadh to attack the Rohillas for payment), the trial and execution of Nanda Kumar/Nandakumar (1775 — accused of forgery and hanged, critics alleged it was judicial murder to silence Hastings' critics), and the wars against Mysore (First and Second Anglo-Mysore Wars) and the Marathas (First Anglo-Maratha War). He was impeached by the British Parliament in 1788 on charges including corruption and maladministration, with Edmund Burke leading the prosecution. The trial lasted seven years and ended in acquittal in 1795, but the proceedings helped establish the principle that colonial administrators could be held accountable.
Cornwallis and the Permanent Settlement
Lord Cornwallis (Governor-General 1786-1793) is significant for both administrative and revenue reforms. His most important measure was the Permanent Settlement of Bengal (1793) — a land revenue system that fixed the revenue demand in perpetuity and made zamindars the proprietors of the land. The Cornwallis Code (1793) separated judicial and revenue functions, establishing a clear distinction between executive and judicial powers. He introduced the principle that British officers should occupy all top positions in the administration — the 'Cornwallisation' of the Indian Civil Service excluded Indians from senior posts (those paying Rs 500 per month or above). Cornwallis reformed the police system by replacing zamindari police with a regular police force under district magistrates. He divided Bengal into districts, each under a Collector and Magistrate. He led the Third Anglo-Mysore War (1790-92) personally, defeating Tipu Sultan and signing the Treaty of Seringapatam. His administrative legacy was the creation of a professional, if exclusivist, bureaucratic system that survived in modified form throughout British rule.
Anglo-Burmese Wars and Southeast Asian Expansion
The British expansion extended beyond the Indian subcontinent into Burma (Myanmar) through three Anglo-Burmese Wars. First Anglo-Burmese War (1824-26): The most expensive war the Company fought up to that time. The Burmese under King Bagyidaw had expanded into Assam, Manipur, and Arakan, threatening British Bengal. The Treaty of Yandabo (1826) forced Burma to cede Assam, Manipur, Arakan, and Tenasserim to the British and pay an indemnity of one crore rupees. Second Anglo-Burmese War (1852): Fought under Dalhousie on flimsy pretexts. The British annexed Pegu (Lower Burma) by right of conquest — Dalhousie did not even bother signing a treaty. Third Anglo-Burmese War (1885): Lord Dufferin completed the conquest of Burma, annexing Upper Burma (including Mandalay) after deposing King Thibaw. By 1886, all of Burma was a province of British India. The Burmese Wars illustrated the pattern of incremental expansion — each war led to territorial gains that created new frontiers requiring further expansion. Assam's annexation from Burma (Treaty of Yandabo) later proved significant for the tea industry that transformed Assam's economy.
Lord Dalhousie — The Great Annexationist
Lord Dalhousie (Governor-General 1848-56) was the most aggressive expansionist among the Governor-Generals. His Doctrine of Lapse was the primary tool of annexation, but he also used other grounds. States annexed under the Doctrine of Lapse: Satara (1848 — the first), Jaitpur and Sambalpur (1849), Baghat (1850), Udaipur (1852), Jhansi (1853 — Rani Lakshmibai's adopted son Damodar Rao was refused recognition), and Nagpur (1854). States annexed by right of conquest: Punjab (1849, after the Second Anglo-Sikh War) and Pegu/Lower Burma (1852, Second Anglo-Burmese War). States annexed on grounds of misgovernance: Awadh (1856 — the Nawab Wajid Ali Shah was deposed despite no evidence of disloyalty to the British; this caused deep resentment among the Awadh taluqdars and soldiers, many of whom joined the 1857 Revolt). Dalhousie also introduced significant modernizing measures: railways (first line Bombay-Thane, 1853), telegraphs (first line Calcutta-Agra, 1854), a modern postal system (Penny Post, 1854), the Public Works Department, and the Indian Engineering College at Roorkee (now IIT Roorkee). He is described as 'the maker of modern India' by some British historians, but his annexation policies directly caused the Revolt of 1857.
Conquest of Sindh
The annexation of Sindh (1843) by Sir Charles Napier is one of the most controversial episodes of British expansion. The Amirs (rulers) of Sindh had signed a treaty with the British in 1838-39 during the First Afghan War, allowing British troops to pass through their territory. After the disastrous British retreat from Kabul (1842), Napier was sent to Sindh to restructure the treaty. He provoked the Amirs by demanding increasingly onerous terms, and when they resisted, he attacked. The Battle of Miani (February 17, 1843) and the Battle of Dubba (March 24, 1843) resulted in decisive British victories, and Sindh was annexed. The annexation was criticized even in Britain — the Governor-General Lord Ellenborough had arguably exceeded his authority in authorizing it. In the House of Commons, it was called 'the most infamous and atrocious transaction' in British Indian history. Napier is said to have sent the famous punning dispatch 'Peccavi' (Latin for 'I have sinned'/'I have Sindh'), though this was actually a joke published in Punch magazine. The Sindh annexation, like others, followed the pattern of first signing defensive treaties with Indian rulers, then finding excuses to violate them.
Impact of British Expansion on Indian Society
The British conquest fundamentally transformed Indian political and social structures. Politically: independent Indian kingdoms were reduced to princely states under British paramountcy — by 1857, there were approximately 565 princely states, all subordinate to British authority. The traditional ruling classes lost power, creating deep resentment. Militarily: Indian armies were reorganized — the Company maintained a large sepoy army (Indian soldiers commanded by British officers) that outnumbered British troops approximately 5:1. The 'martial races theory' categorized Indian communities as 'martial' or 'non-martial,' favoring recruitment from Punjab, Nepal, and certain castes. Economically: conquered territories were integrated into the British economic system — raw materials flowed to Britain, and manufactured goods returned. Socially: the old social order was disrupted — traditional elites lost power, new intermediary classes (zamindars, bania traders, English-educated intelligentsia) emerged. The legal system was transformed from a mix of Islamic and Hindu customary law to a codified Anglo-Indian legal system. The cumulative effect of these transformations created the conditions for the Revolt of 1857 and, ultimately, for the Indian national movement.
Exam-Critical Distinctions
Several distinctions are critically important for examinations and are frequently tested. (1) Plassey vs Buxar: Plassey (1757) was won by conspiracy (Mir Jafar's betrayal), while Buxar (1764) was a decisive military victory — Buxar is militarily more significant. (2) Subsidiary Alliance vs Doctrine of Lapse: Subsidiary Alliance (Wellesley) kept Indian states nominally independent but controlled; Doctrine of Lapse (Dalhousie) directly annexed states. (3) Awadh was NOT annexed under the Doctrine of Lapse — it was annexed on grounds of 'misgovernance' (1856). (4) The Nizam of Hyderabad was the FIRST to accept the Subsidiary Alliance (1798), not the last. (5) Warren Hastings (Governor-General, not Governor) is different from Lord Hastings (Governor-General during the Third Anglo-Maratha War). (6) Lord Cornwallis fought the Third Anglo-Mysore War; Lord Wellesley fought the Fourth Anglo-Mysore War and Second Anglo-Maratha War. (7) The Treaty of Allahabad (1765) gave Diwani rights, not sovereignty — the distinction between Diwani (revenue) and Nizamat (administration) is crucial. (8) Punjab was annexed by 'right of conquest,' not the Doctrine of Lapse. (9) Lord Mountbatten was the last Viceroy but the first Governor-General of free India; C. Rajagopalachari was the last Governor-General.
Relevant Exams
British expansion is one of the most heavily tested areas in Modern Indian History. UPSC Prelims frequently asks about the Subsidiary Alliance, Doctrine of Lapse (which states were annexed and on what grounds), the significance of Buxar vs Plassey, and Anglo-Mysore/Sikh War treaties. SSC and RRB exams focus on matching battles with their dates, treaties, and key figures.
