Treaty of Bassein and British-Maratha Politics

The Treaty of Bassein was signed on December 31, 1802, between the British East India Company and Peshwa Baji Rao II at Vasai (Bassein). It resulted from intense internal rivalries within the Maratha Confederacy that culminated in the Battle of Poona. By accepting the terms of a subsidiary alliance, the Peshwa surrendered his political independence in exchange for British military assistance to restore him to power in Pune. This agreement dismantled the unified structure of the Maratha Empire, brought the core of Western India under British paramountcy, and directly triggered the Second Anglo-Maratha War (1803–1805).

Historical Background and Maratha Rivalries

The stability of the Maratha Confederacy deteriorated rapidly following the deaths of key statesmen Mahadji Shinde in 1794 and Nana Phadnavis in March 1800. In their absence, the young Peshwa Baji Rao II engaged in political intrigues to weaken the regional Maratha chiefs, particularly the Holkars of Indore and the Shindes of Gwalior.

Escalation to the Battle of Poona

• Execution of Vithoji Holkar: In April 1801, Baji Rao II had Vithoji Holkar, brother of Jaswantrao Holkar, brutally executed by being trampled by an elephant in Pune.
• Maratha Civil War: Seeking revenge, Jaswantrao Holkar marched toward Pune to depose Baji Rao II and his ally, Daulat Rao Shinde.
• Battle of Poona (October 25, 1802): Jaswantrao Holkar defeated the combined armies of Peshwa Baji Rao II and Daulat Rao Shinde at Hadapsar near Pune.
• Flight to Bassein: Holkar installed Amrut Rao’s son, Vinayakrao, as the new Peshwa in Pune. Baji Rao II fled to the coastal town of Bassein under British protection aboard a warship.

Terms of the Treaty of Bassein

Governor-General Lord Wellesley used the Peshwa’s vulnerability to enforce the Subsidiary Alliance system, which Baji Rao II formally signed on December 31, 1802.

Key Conditions and Concessions

• Stationing of Subsidiary Force: The British agreed to station a permanent force of six battalions of native infantry with field artillery in the Peshwa’s territories.
• Territorial Cessions: To maintain this subsidiary force, the Peshwa ceded territories yielding an annual revenue of 26 lakh rupees, including districts in Gujarat and lands along the Narmada and Tapti rivers.
• Surrender of Foreign Policy: The Peshwa agreed not to negotiate with any foreign power or declare war/peace without prior British consent.
• Surrender of Maratha Hegemony: The Peshwa renounced all historic claims of Chauth and Sardeshmukhi over the Nizam of Hyderabad and the Gaekwad of Baroda.
• Expulsion of Europeans: The Peshwa pledged to expel all non-British European officers, engineers, and mercenaries from his service.
• Arbitration Rights: The Peshwa accepted British arbitration in all existing disputes between Pune, Hyderabad, and Baroda.

British Gains vs. Maratha Reaction

The Treaty of Bassein altered the balance of power in South Asia, handing the British strategic dominance over Western India without an immediate, full-scale campaign.

Military and Geopolitical Impact

• Strategic Encirclement: British troops occupied Pune on May 13, 1803, and restored Baji Rao II to the throne, effectively surrounding the remaining Maratha kingdoms.
• Breakdown of Maratha Sovereignty: Historian Karl Marx noted that the Treaty of Bassein completed the subjugation of India by destroying its last major native empire from within.
• Rejection by Chiefs: Independent Maratha leaders—Daulat Rao Shinde, Raghuji Bhonsle II of Nagpur, and Jaswantrao Holkar—refused to recognize the treaty, viewing it as a betrayal of national independence.

Second Anglo-Maratha War (1803–1805)

The humiliation of the Peshwa’s submission pushed Shinde and Bhonsle into an immediate military alliance against the British, sparking the Second Anglo-Maratha War.

Outbreak and Major Engagements

• Battle of Assaye (September 1803): Major-General Arthur Wellesley defeated the combined forces of Shinde and Bhonsle in Maharashtra.
• Battle of Laswari (November 1803): General Gerard Lake crushed Shinde’s Northern Army in Rajasthan, gaining control over Delhi and Agra.
• Treaty of Deogaon (December 1803): Raghuji Bhonsle II surrendered and ceded Cuttack and Balasore to the British.
• Treaty of Surji-Anjangaon (December 1803): Daulat Rao Shinde surrendered the Ganga-Yamuna Doab, Delhi-Agra region, and parts of Gujarat to the British.
