- Gaekwad of Baroda
- Raghuji Bhonsle of Nagpur,
- Malhar Rao Holkar of Indore and
- Ranaji Scindia of Gwalior.
Peshwa Baji Rao organized them into one union known as the confederacy and allowed them to levy the taxes and to enjoy the maximum autonomy. But they had to pay the share of the state income and work under the Peshwa and are also required to join the Peshwa in military campaign against the common enemy.
- The Maratha armies under their chiefs started to overrun the whole of India. They invaded Bengal many times.
- At the end of 1751 A.D., the Nawab of Bengal gave them Orissa. During this period the state of Mysore also became ready to pay the tribute to the Maratha power.
- They also defeated the Nizam of Hyderabad at Udgir who was forced to give away his vast territories to Marathas.
- In the North they reached Delhi in 1752 A.D. In 1753, they captured Delhi from Ahmed Shah Abdali.
- In 1758 A.D., Punjab was caputured from the son of Ahmed Shah Abdali.
- Thus by 1761 A.D., the Maratha Kingdom reached its heights of prestige and glory and their Kesaria flag flew over the fort of which they attacked.
- There was no unity among the Marathas. There were a number of kingdoms in the Marathas Empire. They always fought with one another.
- The policy of expansion itself proved a cause of failure of the Maratha Empire, because it was very difficult for them to have control over the vast empire which extended from Attack to Cuttak.
- The Marathas were defeated in the Third Battle of Panipat. This defeat made the way to the rise of British power in India, because after the Marathas no strong power was there in India which could face the British.
- Their policy of plundering the Hindu States made them enemies of Jats, Sikhs and Rajputs.
- The Marathas had not promoted industry, agriculture and trade. They even lost the goodwill of the people because they collected a number of taxes from them, such as Chauth and Sardeshmukhi. Thus they failed to establish a powerful state and a strong empire.
