The term "Peshwa" refers to the prime minister of the Maratha Empire in India, particularly during the 18th century. The Peshwa was responsible for the administration and governance of the empire, acting as the chief executive officer. The most notable Peshwas were from the Bhat family, with Balaji Vishwanath and Baji Rao I being prominent figures who expanded the empire's influence. The Peshwas played a crucial role in the Maratha's rise to power, establishing a strong central authority. They were instrumental in military campaigns and diplomatic relations, helping to shape the political landscape of India during their time. The position of Peshwa eventually declined with the rise of British colonial power in the 19th century.
