Expansion & consolidation of British rule

The Foundations: Plassey and Buxar

The Company's transformation from a trading corporation into a territorial sovereign began on the Bengal plain. The Battle of Plassey (23 June 1757), won by Robert Clive through the treachery of Mir Jafar against Siraj-ud-Daulah, delivered Bengal's revenues into Company hands and installed a puppet Nawab. The decisive consolidation came at the Battle of Buxar (22 October 1764), where Hector Munro defeated the combined armies of Mir Qasim (Bengal), Shuja-ud-Daulah (Awadh) and the Mughal Emperor Shah Alam II. Buxar made the Company the real military master of north India.

The Treaty of Allahabad (1765) formalised the gains: Shah Alam II granted the Company the Diwani (the right to collect revenue) of Bengal, Bihar and Orissa, while a nominal administration (the Nizamat) remained with the Nawab. This Dual System of Government, devised by Clive, divorced power from responsibility and produced the catastrophic Bengal Famine of 1770. Warren Hastings ended the dual system in 1772 by bringing the administration directly under Company control.

The Instruments of Expansion

The Company expanded through three recurring instruments that UPSC repeatedly tests. First, outright annexation after war: the four Anglo-Mysore Wars (1767-99) ended with Tipu Sultan's death at Seringapatam (4 May 1799); the three Anglo-Maratha Wars (1775-1818) culminated in the dissolution of the Peshwaship under Lord Hastings; and the two Anglo-Sikh Wars annexed Punjab in 1849 under Dalhousie.

Second, the Subsidiary Alliance systematised by Lord Wellesley (1798-1805). Under it an Indian ruler disbanded his own forces, accepted a Company garrison, ceded territory or paid a subsidy for its upkeep, surrendered control of foreign relations and hosted a British Resident. Hyderabad (1798) was the first major signatory; Awadh, Mysore, Tanjore and the Marathas followed. The alliance disarmed states while leaving rulers nominally on their thrones — a cheap, deniable imperialism.

Third, the Doctrine of Lapse, applied aggressively by Lord Dalhousie (1848-56), held that an Indian state without a natural heir lapsed to the Company, denying the Hindu custom of adoption. Satara (1848), Jaitpur and Sambalpur (1849), Jhansi (1853) and Nagpur (1854) were annexed under it. Awadh was annexed in 1856 on the pretext of misgovernment. These annexations dispossessed dynasties such as Nana Saheb (denied his pension) and Rani Lakshmibai of Jhansi, sowing the grievances that erupted in 1857.

By 1857 the Company directly governed roughly two-thirds of the subcontinent and exercised paramountcy over the rest. The pattern — war, then a treaty extracting territory or subsidy, then administrative absorption — is the analytical thread a candidate must be able to trace from Plassey to Punjab.

Why this matters for the exam

This lesson serves Prelims GS (factual recall of battles, treaties, governors-general and the states they annexed) and Mains GS-1 under the syllabus head 'modern Indian history from about the middle of the eighteenth century until the present — significant events, personalities, issues.' Expansion is the causal backbone for two later high-yield topics: the causes of the 1857 Revolt (Lesson 3) and the economic critique of colonialism (drain of wealth, deindustrialisation).

The PYQ pattern and high-yield facts

UPSC Prelims has repeatedly tested matching governors-general to their acts: Cornwallis (Permanent Settlement, 1793; Civil Service reform), Wellesley (Subsidiary Alliance), William Bentinck (abolition of sati 1829; suppression of thuggee; Charter Act of 1833), and Dalhousie (Doctrine of Lapse; railways 1853; telegraph; Wood's Despatch 1854; first Public Works Department). A 2018 Prelims question probed which states were annexed under the Doctrine of Lapse; a recurring trap is including Awadh, which was annexed in 1856 for alleged misgovernment, not under Lapse.

For Mains, examiners reward an analytical thread rather than a chronicle: show how military victory, the Subsidiary Alliance and Lapse formed a single integrated machinery of paramountcy, and connect dispossession (Nana Saheb, Jhansi, Awadh's disbanded soldiers) directly to 1857. Retain these anchors precisely:

• Plassey 1757; Buxar 1764; Treaty of Allahabad 1765 (Diwani granted by Shah Alam II).
• Dual System 1765-72, ended by Warren Hastings.
• Subsidiary Alliance — Wellesley; Hyderabad first (1798); five obligations (disband army, host garrison, cede territory/pay subsidy, surrender foreign relations, accept a Resident).
• Doctrine of Lapse — Dalhousie; Satara 1848, Jhansi 1853, Nagpur 1854.
• Anglo-Mysore (4), Anglo-Maratha (3), Anglo-Sikh (2) wars with terminal dates 1799, 1818, 1849.

In Mains answers, cite the Regulating Act 1773 and Pitt's India Act 1784 as the constitutional scaffolding that brought the expanding territories under parliamentary supervision — examiners credit candidates who link administrative consolidation to territorial conquest rather than treating them separately.
