Third Anglo-Mysore War (1790–1792)

The Third Anglo-Mysore War (1790–1792) stands as a watershed moment that dramatically reshaped the political balance in South India, marking a significant step in the consolidation of British East India Company power. This intense military confrontation pitted the formidable ruler Tipu Sultan of Mysore against a powerful triple alliance led by the British East India Company, alongside their regional allies, the Marathas and the Nizam of Hyderabad. The war culminated in the severe and humiliating Treaty of Seringapatam in 1792, a critical event for students and aspirants preparing for UPSC and other competitive exams as it profoundly illustrates the strategic decline of native states and the growing, relentless British dominance over the Indian subcontinent.

Third Anglo-Mysore War (1790-1792): Underlying Causes and Formation of British Strategic Alliances

• The direct catalyst for the war was Tipu Sultan's strong opposition to the territorial expansion and controversial land acquisitions made by Travancore, a kingdom strategically aligned with the British.

  The stage for the third conflict was set by the continuing tension between the expansionist ambitions of Mysore and the protective maneuvers of the British over their allies, leading to an inevitable clash of sovereign interests.

  • (i) A specific flashpoint occurred when the kingdom of Travancore, acting under the implicit protection of the British, proceeded to purchase the strategic Dutch-held towns of Jalkottal and Cannanore, both situated within the boundaries of Cochin.
  • (ii) Since the region of Cochin was historically considered a feudatory state under the authority of Tipu Sultan, the ruler viewed this transaction—the transfer of key territories—as a direct and undeniable violation of his sovereign rights and an encroachment upon his dominion, leading him to declare war on Travancore in April 1790.
  • (iii) The British Governor-General, Lord Cornwallis, swiftly seized upon this declaration of war as the perfect pretext to mobilize a powerful and coordinated anti-Mysore coalition, successfully forging an alliance with the formidable Marathas and the powerful Nizam of Hyderabad to decisively challenge the strength of Mysore.

• Course of the War (1790-1792): Tipu Sultan's Initial Resilience and Lord Cornwallis's Decisive Intervention

  The conflict commenced with surprising initial resistance from Tipu Sultan's forces, but the overall trajectory of the war shifted dramatically and decisively in favor of the British following the direct assumption of military command by Lord Cornwallis.

  • Key Military Campaigns and Shifting Fronts: Initial Setbacks and Strategic British Victories

    The war saw a series of rapid campaigns and counter-campaigns across the Deccan, testing the mettle of both Tipu Sultan and the expanding power of the British forces.

    • (i) In the initial stages of 1790, the English forces, then led by General Meadows, faced significant military setbacks and were defeated by the strategically brilliant forces of Tipu Sultan, momentarily halting the British advance.
    • (ii) Recognizing the need for strong leadership, Lord Cornwallis personally assumed command of the British army in 1791, leading a vigorous campaign that culminated in the successful capture of the strategically vital city of Bangalore in March 1791, immediately turning the tide and paving the way for the advance toward Seringapatam.
    • (iii) Although the British briefly managed to seize the important trading center of Coimbatore, the forces of Tipu Sultan swiftly and successfully recaptured the city, providing a demonstration of his enduring military prowess and capability for powerful counter-attack.
    • (iv) The ultimate, decisive assault was meticulously planned and launched against Tipu Sultan’s capital, Seringapatam; this monumental siege involved the overwhelming, combined military might of the British, the Marathas, and the Nizam, ultimately succeeding in overwhelming the defenses of the Mysore kingdom.

• The Treaty of Seringapatam (1792): Humiliating Provisions and the Territorial Partition of Mysore

  The conclusion of the war resulted in the imposition of the Treaty of Seringapatam, a document that delivered a crushing blow to Mysore, severely curtailing its size and influence, and dramatically expanding the territorial footprint of the victorious British and their allies across the region.

  • Crippling Indemnity and Loss of Sovereign Territory: The Punishment for Tipu Sultan

    The terms dictated by the treaty were intentionally harsh, designed not only to end the immediate conflict but to permanently cripple Mysore's power and ensure Tipu Sultan could no longer pose a significant threat to British interests.

    • (a) Tipu Sultan was summarily compelled to cede nearly half of his valuable kingdom’s territory to the triumvirate of victors, marking a colossal loss of strategic and economic land.
    • (b) The British themselves successfully acquired several key, strategically important regions, including Baramahal, the resource-rich area of Dindigul, and the crucial western trade territories of the Malabar coast, securing vital trade routes and coastal access.
    • (c) The Marathas were suitably rewarded for their participation by gaining vast lands surrounding the Tungabhadra river and its various tributaries, strengthening their southern borders.
    • (d) The Nizam of Hyderabad also received significant territories, including lands stretching from the Krishna river all the way to beyond the Pennar river, fundamentally altering the political map of the Deccan.
    • (e) A staggering war indemnity of ₹3 crore was forcefully imposed upon Tipu Sultan, a financial burden that was crippling; furthermore, as an ultimate and humiliating guarantee for the full and timely payment, his two young sons were taken hostage by the British.

• Summary: Historical Significance of the Third Anglo-Mysore War and Consolidation of British Dominance

  The Third Anglo-Mysore War (1790–1792), decisively triggered by Tipu Sultan’s response to the Travancore land deal, culminated in a strategic and comprehensive victory for the British East India Company and their powerful allies. The resulting and punishing Treaty of Seringapatam in 1792 effectively crippled the power of Mysore, forcing Tipu Sultan to surrender vast territories and accept a crushing financial indemnity. This conflict fundamentally solidified the British as the undisputed paramount power in South India and strategically laid the essential groundwork for the final collapse and eventual annexation of Mysore during the subsequent Fourth Anglo-Mysore War. Consequently, this war remains a key historical event for students and aspirants to thoroughly understand the complex process of British power consolidation in India and the progressive decline of independent native states.
