Shahu I, by Shivram Chitari |left
Tarabai, the senior widow of the third Maratha ruler,
Rajaram I, was granted asylum by her nephew, Chhatrapati Shahu I, after being released from captivity by her stepson
Sambhaji II of
Kolhapur. During the 1740s, in Shahu I’s final years, Tarabai presented to him a boy named
Rajaram II, claiming he was her grandson and a direct descendant of the first Maratha ruler,
Shivaji I. Shahu I accepted this claim and adopted the boy. Upon Shahu I’s death in 1749, Rajaram II succeeded him as Chhatrapati. In 1750, while Balaji Baji Rao was campaigning against the Nizam of Hyderabad, Tarabai urged Rajaram II to dismiss him from the office of Peshwa. When the Chhatrapati refused, she imprisoned him in a dungeon at Satara on 24 November 1750, claiming that he was an impostor whom she had falsely presented as her grandson. Tarabai failed to secure support from other Maratha nobles or from the
Nizam,
Salabat Jung, but she managed to gain the backing of
Umabai Dabhade. Umabai was the matriarch of the
Dabhade family, hereditary
Senapati or commanders-in-chief of the Maratha Empire and controllers of large territories in
Gujarat. Her husband had been killed by the Mughals, and her eldest son by Baji Rao I for rebelling against Shahu I. Although Shahu I had pardoned the Dabhades and allowed them to retain their
jagirs and titles on the condition that they remit half their Gujarat revenues to the royal treasury, the family had never done so. After Shahu I’s death, Balaji Baji Rao—facing an empty treasury—insisted that they honor this agreement. When Umabai met him in 1750, she argued that the arrangement had been made under duress; the Peshwa rejected her claim. In support of Tarabai’s rebellion, Umabai dispatched a force of 15,000 troops under her lieutenant
Damaji Rao Gaekwad. Gaekwad advanced toward Pune, causing Balaji Baji Rao’s mother Kashibai and grandmother Radhabai to flee to
Sinhagad. While encamped at Pargaon near Pune, Gaekwad received a letter from the Peshwa loyalist Mahadji Purandare, denouncing him as a traitor. Gaekwad then redirected his march toward Satara. He defeated Mahadji’s brother, Trimbakrao Purandare, at Nimb—a small town north of Satara—but was later defeated on 15 March 1751 at the
Venna River and forced to retreat with heavy losses. On learning of the rebellion, Balaji Baji Rao marched swiftly from the Mughal frontier, covering 400 miles in 13 days. He reached Satara on 24 April 1751, captured the Yavateshwar garrison, and defeated Tarabai’s troops. After Gaekwad’s forces were surrounded, Balaji Baji Rao demanded that he cede half of Gujarat and pay a
war indemnity of ₹2,500,000. Gaekwad refused, saying he was only a subordinate acting under Umabai’s orders. On 30 April, Balaji Baji Rao launched a surprise attack, forcing Gaekwad’s surrender. Balaji Baji Rao then besieged Satara Fort, demanding that Tarabai release Rajaram II, whose health had declined during captivity. She refused, and Balaji Baji Rao withdrew to Pune rather than engage in a prolonged siege. A subsequent mutiny by Tarabai’s own troops weakened her position. Realizing the futility of continued resistance, she sought peace. She met Balaji Baji Rao in Pune, dismissed her adviser Baburao Jadhav, and accepted the supremacy of the Peshwa’s office. On 14 September 1752, both swore mutual peace at the Khandoba temple in
Jejuri, where Tarabai declared under oath that Rajaram II was not her grandson but an impostor of the Gondhali caste. Despite this, Balaji Baji Rao retained Rajaram II as the titular
Chhatrapati, a ceremonial and powerless figurehead. In May 1751, Balaji Baji Rao arrested Damaji Gaekwad and his relatives and imprisoned them in Pune. The Dabhades were later detained and stripped of their jagirs and titles. When Damaji refused to yield half of Gujarat’s territory, he was confined in
Lohagad Fort. Eventually, after prolonged negotiations, he agreed in March 1752 to abandon the Dabhades and ally with the Peshwa. In return, Balaji Baji Rao appointed him as the Maratha chief of Gujarat and promised military support against the Mughals. Damaji consented to pay an annual tribute of ₹525,000 and a one-time payment of ₹1,500,000, and to maintain a cavalry of 20,000 horses for the Peshwa's services.
