Balaji Vishwanath assisted the Maratha Emperor Shahu to consolidate power after a period of civil war and attacks from the Mughals. He helped establish the Maratha State and came from a Konkani Brahmin family from coastal Maharashtra. Bajirao I was a legendary general and Peshwa of the Maratha Empire from 1720-1740, expanding the Empire's territory significantly. He came from the Bhat family and was the son of Balaji Vishwanath. His successors also contributed to the growth of the Maratha Empire, though internal conflicts and attacks from outsiders also challenged it.
