Nana Govind Dhondu Pant

Nana Saheb Peshwa II (19 May 1824 – 24 September 1859), born as Dhondu Pant

Indian Peshwa of the Maratha empire, aristocrat and fighter, who led the rebellion in Cawnpore (Kanpur) during the 1857 rebellion. As the adopted son of the exiled Maratha Peshwa Baji Rao II, Nana Saheb believed that he was entitled to a pension from the East India Company, but the underlying contractual issues are rather murky. The Company's refusal to continue the pension after his father's death, as well as what he perceived as high-handed policies, led him to join the rebellion. He forced the British garrison in Kanpur to surrender, then murdered the survivors, gaining control of Kanpur for a few days. He later disappeared, after his forces were defeated by a British force that recaptured Kanpur. He later fled to Nepal, where he was said to have died in September 1859.
