📌 The Third Anglo-Maratha War: Background, Decisive Course, and Result ()
The background of the Third Anglo-Maratha War was steeped in escalating British expansionism and the fractured, yet determined, resistance of the Maratha states. The events leading up to the final confrontation involved a calculated British effort to eliminate any remaining challenge to their authority, capitalizing on existing Maratha weaknesses.
Key background causes and developments:
- (i) The aggressive imperialist policies pursued by Governor-General Lord Hastings aimed explicitly at imposing uncontested British paramountcy across India, coinciding with commercial shifts following the Charter Act of 1813, which compelled the Company to actively seek new inland territories and markets after losing its trade monopoly.
- (ii) The issue of the Pindaris, who were essentially unemployed irregular Maratha mercenaries, provided the immediate pretext for war, as their widespread raids into Company lands led the British to accuse the Marathas of harboring and supporting them.
- (iii) The British campaign successfully dismantled the core leadership of the Pindaris, forcing key leaders like Amir Khan and Karim Khan to surrender, while the notable Pindari chief, Chitu Khan, fled into the dense jungles, effectively neutralizing this threat.
- (iv) The lingering resentment caused by the humiliating Treaty of Bassein (), signed by the Peshwa after the Second Anglo-Maratha War, continued to anger other powerful Maratha chiefs who viewed the subsidiary alliance as a catastrophic surrender of their independence.
- (v) Lord Hastings’ sustained military campaigns aimed at eliminating the Pindaris were perceived by the Maratha aristocracy as a direct threat to their remaining internal sovereignty, pushing the disparate Maratha chiefs toward a final attempt to resist.
- (vi) This rising tide of resentment culminated when Bajirao II, the Peshwa, made a final attempt in to unite the various Maratha chiefs into open resistance against the growing power of the British.
📌 Course of the Third Anglo-Maratha War: Battles and Maratha Disunity ()
The war commenced with several brave, yet uncoordinated, Maratha offensives that tragically exposed deep-seated disunity and a critical lack of administrative strength required to defeat the organized British forces.

The Initial Maratha Offensives and Confrontations
Driven by a final surge of desperation, major Maratha leaders initiated attacks on British strongholds, hoping to overturn the subsidiary alliances and reassert their autonomy.
- (i) The Peshwa, Bajirao II, made the initial aggressive move by attacking the British Residency located at Poona, signaling the formal beginning of hostilities and challenging the terms of the subsidiary alliance system.
- (ii) Following suit, Appa Sahib of Nagpur, the ruler of the Bhonsle dominion, mounted an assault on the British residency situated at Nagpur, demonstrating a shared but fragmented desire among the chiefs to throw off British control.
- (iii) Concurrently, the Holkars of Indore prepared their forces for war, but the overall Maratha effort was fatally undermined by a lack of unified command, poor coordination, and weakening administrative capacity.
The Deep Internal Weakness of the Maratha Confederacy
Beyond the lack of military coordination, fundamental internal weaknesses severely eroded the Maratha capacity to wage a successful war against a modernized power like the East India Company.
- (a) The critical situation within the Holkar state arose following the death of Jaswantrao Holkar, after which his successor, Tulsi Bai, proved ineffective due to the influence of corrupt advisors surrounding her.
- (b) Simultaneously, the regional powers of the Bhonsles at Nagpur and the Sindhias at Gwalior experienced political instability, rendering them unable to contribute decisively to the collective war effort.
- (c) These internal divisions provided the British with a clear strategic advantage, enabling them to prevent the Peshwa from regaining effective control or military authority over the Maratha confederacy.
📌 The Decisive Result: Collapse of Maratha Sovereignty ()
The military campaign resulted in swift British victories, leading to the ultimate collapse of the Maratha Confederacy and the final end of their independent sovereignty.
Major Military Defeats and Crushing British Victories

Subjugation Enforced through Important Treaties Signed

- (i) In , the Treaty of Poona was signed with the Peshwa, severely curtailing his power even before the main military defeats.
