The Hindu Marathas long had lived in the Desh region around Satara, in the western portion of the Deccan plateau, where the plateau meets the eastern slopes of the Western Ghats mountains. They had resisted incursions into the region by the Muslim Mughal rulers of northern India. Under their ambitious leader Chhatrapati Shivaji Maharaj, the Maratha freed themselves from the Muslim sultans of Bijapur to the southeast. Subsequently, under the able leadership of Brahmin prime ministers (Peshwas), the Maratha Empire reached its zenith; Pune, the seat of Peshwas, flowered as a centre of Hindu learning and traditions.
