Third Anglo-Mysore War

The immediate occasion for the Third Anglo-Mysore War was East India Company intervention in defense of Travancore, whose raja had purchased the Dutch fortifications at Cranganore and Ayacottah in 1789 — territory that Tipu Sultan of Mysore regarded as within his sphere and that he moved to seize by force at the close of that year^[1]. Tipu's attack on the Travancore Lines in late December 1789 gave the Company the casus belli it needed, since Travancore was a treaty ally whose defense the Company had formally guaranteed. What followed was not merely a punitive expedition but the activation of a coalition that had been assembling for years against Mysore's regional power.

The structural political cause was the unfinished business of the Second Anglo-Mysore War (1780–1784). The Treaty of Mangalore that ended it had been a negotiated stalemate — deeply humiliating to the Company and to British prestige in India — and Tipu Sultan, who had succeeded his father Hyder Ali during that conflict, remained in British strategic thinking an unreduced threat^[2]. Governor-General Lord Cornwallis arrived in India in 1786 committed to building the encircling alliance that would neutralize Mysore permanently. Diplomatic pressure and territorial inducement brought the Nizam of Hyderabad and the Maratha Confederacy into a triple alliance with the Company, surrounding Mysore on three sides before the first shot of the 1790 campaign was fired^[3].

Beneath the immediate political trigger lay a decades-long competition for dominance over the Deccan and southern India. Mysore under Hyder Ali and then Tipu had expanded aggressively, absorbing Coorg, pressing into Malabar, and threatening the Carnatic — territories in which the Company had direct commercial and revenue interests^[4]. Tipu's effort to control the pepper and spice trade of the Malabar coast placed him in direct economic competition with Company commercial networks, and his suppression of local populations — including the forced conversions and deportations that disrupted communities in Coorg and South Kanara — generated internal resistance that the Company could exploit^[5][6].

Ideological friction intensified the structural antagonism. Tipu's correspondence with the Ottoman Empire, the Amir of Afghanistan, and revolutionary France — none of which produced material assistance but all of which alarmed Calcutta — reinforced the Company's perception of Mysore as an irreconcilable power that would seek any foreign lever against British interests^[7]. Tipu's self-presentation as a jihad-waging sultan, whatever its precise doctrinal content, was read by British officials and by Hindu and Christian communities within his domains as a signal of religious coercion, lending the coalition war a legitimizing narrative that extended beyond pure balance-of-power calculation^[8]. The Battle of Calicut and the broader campaign that followed were thus the military expression of rivalries — territorial, commercial, diplomatic, and cultural — that no treaty short of Mysore's permanent diminishment could have resolved.

The formal conclusion of the Third Anglo-Mysore War came with the Treaty of Seringapatam in March 1792^[1], imposed on the East India Company's principal adversary, Tipu Sultan, after the combined allied forces had driven to the walls of his capital. The treaty's terms were punishing: Tipu was compelled to cede roughly half of his kingdom's territory to the victorious coalition, surrender two of his sons as hostages pending payment of a substantial war indemnity, and accept the permanent dissolution of his western coastal ambitions^[2]. The territorial redistribution was divided among the three allied parties — the Company, the Nizam of Hyderabad, and the Maratha Confederacy — establishing a precedent for coordinated partition that the British would exploit again in the Fourth Anglo-Mysore War less than a decade later.

For the Company, the settlement produced a major strategic consolidation in southern India. The ceded districts extended British-controlled territory across the Malabar coast and through the interior plateau, severing Mysore from direct contact with potential French partners along the western seaboard^[3]. Lord Cornwallis, who had directed the final campaign, secured his reputation as an imperial administrator despite having surrendered an entire army at Yorktown a decade earlier; his conduct of the Mysore operations was widely judged in London as a rehabilitation^[4]. The campaign also demonstrated that the Company could sustain and coordinate a large multi-arm force across difficult terrain, hardening the institutional military confidence that would define its conduct in subsequent Indian wars.

The territorial cessions imposed severe internal strains on Mysore's economy and administrative structure. The loss of productive agricultural districts and port revenues reduced Tipu's fiscal base precisely at the moment he was obligated to raise the indemnity — a structural weakness that constrained his capacity to rebuild and rearm^[5]. Communities in the ceded zones, including Christian populations on the Malabar coast who had suffered heavily under Tipu's earlier campaigns, experienced yet another administrative transition, passing from Mysorean to either Company or Hyderabadi jurisdiction^[6]. The disruption to agrarian and commercial life in these districts was not quickly repaired.

The war's outcome also reordered the regional balance among Indian powers in ways that worked consistently to British advantage. The Maratha Confederacy and the Nizam each received territory, but neither gained the organizational capacity or unified direction that might have made them genuine counterweights to the Company's expanding dominion. The engagement at Calicut and the broader western coastal operations had already eliminated Tipu's ability to contest the Malabar littoral, leaving the Company as the dominant maritime-facing power in the south^[7]. The Nizam in particular grew increasingly dependent on Company military support to maintain his position against Maratha pressure, a relationship that progressively eroded his strategic autonomy.

What the Treaty of Seringapatam did not resolve was Tipu Sultan's determination to recover his position. He resumed diplomatic overtures to France and to the Ottoman Empire through the 1790s, seeking external leverage to offset the Company's structural advantages^[8]. The 1792 settlement thus produced a heavily armed, deeply aggrieved, and territorially truncated Mysore — conditions that made renewed conflict nearly inevitable. The Fourth Anglo-Mysore War of 1798–1799 completed what the third had begun, ending with the fall of Seringapatam, Tipu's death in battle, and the extinction of the Mysore Sultanate as an independent power.
