The First Anglo-Maratha War (1775–1782) was the first of three Anglo-Maratha Wars fought between the British East India Company and Maratha Empire in India. The war began with the Treaty of Surat and ended with the Treaty of Salbai. The war was fought in between Surat and Pune Kingdom saw British defeat and restoration of positions of both the parties before the war. Warren Hastings, the first President and Governor-General of East India Company's provinces in India decided not to attack Poona directly. Background After the death of Madhavrao Peshwa in 1772, his brother Narayanrao became peshwa (prime minister) of the Maratha Empire. Narayanrao was murdered by his palace guards in August 1773, and his uncle Raghunathrao (Raghoba) became Peshwa. However, Narayanrao's wife, Gangabai, gave birth to a posthumous son, who was the legal heir to the throne. The newborn infant was named 'Sawai' Madhavrao (Sawai means "One and a Quarter"). Twelve Maratha chiefs, known as the Baarbhai and led by Nana Phadnavis, directed an effort to install the infant as the new Peshwa and to rule in his name as regents. Raghunathrao, unwilling to give up his position of power, sought help from the British at Bombay and signed the Treaty of Surat on 6 March 1775. According to the treaty, Raghunathrao ceded the territories of Salsette and Bassein (Vasai) to the British, along with part of the revenues from Surat and Bharuch districts. In return, the British promised to provide Raghunathrao with 2,500 soldiers. The British Calcutta Council condemned the Treaty of Surat, sending Colonel Upton to Pune to annul it and make a new treaty with the regency. The Treaty of Purandhar (1 March 1776) annulled that of Surat, Raghunathrao was pensioned and his cause abandoned, but the revenues of Salsette and Broach districts were retained by the British. The Bombay government rejected this new treaty and gave refuge to Raghunathrao. In 1777, Nana Phadnavis violated his treaty with the Calcutta Council by granting the French a port on the West coast. The English retaliated by sending a force towards Pune. Initial stage and Treaty of Purandar (1775–1776) British troops under the command of Colonel Keating, left Surat on 15 March 1775, for Pune. But they were checked by Haripant Phadke at Adas and were totally defeated on 18 May 1775. Casualties for Keating's force, accompanied by Raghunathrao, included 96 killed.
