The document provides a summary of Maratha supremacy in India during the 18th century. It describes how the Maratha empire rose to power under powerful leaders like Balaji Vishwanath, Bajirao Peshwa, and Nana Saheb. Key events included the Marathas conquering much of central and northern India, defeating the Mughals and Nizam of Hyderabad. However, internal divisions and the granting of powerful jagirs to local chieftains weakened centralized control. This ultimately led to the Maratha empire's decline, culminating in their devastating loss to Ahmad Shah Abdali at the Third Battle of Panipat in 1761.
