Maratha Confederacy — Key Changes

Entry	Year	Description	Impact
1	1713	Appointment of Balaji Vishwanath as Peshwa by Shahu, marking the formal beginning of the Peshwa's ascendancy and the gradual shift of power from the Chhatrapati to the chief minister.	Transformed the role of Peshwa from an administrative post to a position of significant political and military authority, laying the groundwork for hereditary Peshwaship and the decentralized Confederacy.
2	1719	Treaty with Mughal Emperor Farrukhsiyar, secured by Balaji Vishwanath, granting Marathas the right to collect Chauth and Sardeshmukhi from six Deccan provinces and recognizing Shahu's claim to the Maratha throne.	Legitimized Maratha revenue claims over vast Mughal territories, providing a legal basis for their expansion and solidifying their financial resources, while formally acknowledging their political existence within the Mughal framework.
3	1750	Sangola Agreement, where Chhatrapati Shahu formally transferred all executive and military powers to the Peshwa, Balaji Baji Rao, making the Peshwa the de facto ruler.	Cemented the Peshwa's supreme authority, reducing the Chhatrapati to a titular head and effectively shifting the administrative capital to Pune, formalizing the decentralized structure of the Confederacy under Peshwa leadership.
4	1782	Treaty of Salbai, ending the First Anglo-Maratha War, which established a 20-year period of peace and recognized Madhavrao II as Peshwa.	Provided a crucial period of stability for the Marathas to recover from internal strife and allowed the British to consolidate power elsewhere, demonstrating Maratha diplomatic strength but also highlighting the potential for future conflict.
5	1802	Treaty of Bassein, signed by Peshwa Baji Rao II with the British, accepting the Subsidiary Alliance system.	A catastrophic 'amendment' to Maratha sovereignty, effectively bringing the Peshwa under British control, alienating other Maratha chiefs, and directly leading to the Second Anglo-Maratha War, marking the beginning of the end for Maratha independence.
