All the Peshwas during the rule of Chhatrapati Shivaji, Sambhaji and Rajaram belonged to Deshastha Brahmin community. The first Peshwa was Moropant Pingle, who was appointed as the head of the Ashta Pradhan (council of eight ministers) by Chhatrapati Shivaji, the founder of the Maratha Empire. The initial Peshwas were all ministers who served as the chief executives to the king. The later Peshwas held the highest administrative office and also controlled the Maratha confederacy. Under the Chitpavan Brahmin Bhat family, the Peshwas became the "de facto" hereditary administrators of the Confederacy. The Peshwa's office was most powerful under Baji Rao I (r. 1720-1740). Under Peshwa administration and with the support of several key generals and diplomats, the Maratha Empire reached its zenith, ruling major areas of India. The subsequent Peshwas brought in autonomy and as a result later on many provinces were controlled and administered by the Maratha nobles such as Scindias and Gaekwads.
