Explanation:

Shahu appointed Peshwa Balaji Vishwanath in 1713. From his time, the office of Peshwa became supreme while Shahu became a figurehead. His first major achievement was the conclusion of the Treaty of Lonavala in 1714 with Kanhoji Angre, the most powerful naval chief on the Western Coast. He later accepted Shahu as Chhatrapati. In 1719, an army of Marathas marched to Delhi after defeating Sayyid Hussain Ali, the Mughal governor of Deccan, and deposed the Mughal emperor. The Mughal Emperors became puppets in the hands of their Maratha overlords from this point on.
