Balaji Baji Rao, often referred to as Nana Saheb I, was the 8th Peshwa of the Maratha Confederacy. He was appointed as Peshwa in 1740 upon the death of his father, the Peshwa Bajirao I.

Shahu I was the fifth Chhatrapati of the Maratha Empire founded by his grandfather, Shivaji I. He was born into the Bhonsle family, and was the son of Sambhaji I and Yesubai. At a young age, he was taken into custody at the Siege of Raigad by Mughal emperor Aurangzeb, and held captive by the Mughals. He was released from captivity after the death of Aurangzeb in the hope of engineering an internecine struggle among the Maratha factions of Tarabai and Shahu. Raja Shahu emerged victorious in the bloody Battle of Khed and was crowned as Chhatrapati.
