Maratha Expansion — Key Changes

Entry	Year	Description	Impact
Shift of Power to Peshwa	c. 1713-1720	The effective administrative and military authority within the Maratha state gradually shifted from the Chhatrapati (monarch) to the Peshwa (prime minister). This transformation was formalized under Balaji Vishwanath, who became the de facto ruler, reducing the Chhatrapati to a titular head. This 'amendment' to the Maratha political structure was crucial for the subsequent expansion, as it centralized executive power in the hands of capable administrators and military leaders.	Enabled a more aggressive and centralized foreign policy, leading to rapid territorial expansion. However, it also created a potential for conflict between the Peshwa and the Chhatrapati, and later, among the Peshwa and the confederate chiefs.
Formation of Maratha Confederacy	c. 1740s	As the Maratha Empire expanded, it became unwieldy for the Peshwa to directly administer all territories. Balaji Baji Rao formalized the Maratha Confederacy, decentralizing power to powerful Maratha families (Holkars, Scindias, Gaekwads, Bhonsles). These chiefs were granted semi-autonomous control over vast regions, maintaining their own armies and administrations, while acknowledging the Peshwa's suzerainty.	Facilitated rapid expansion and effective governance over diverse territories by leveraging local leadership. However, it also led to internal rivalries, weakened central authority, and contributed to disunity, particularly during crises like the Third Battle of Panipat.
Shift in Military Strategy	c. 1740s-1750s	Initially known for guerrilla warfare (Shivaji, Baji Rao I), the Marathas under Balaji Baji Rao and Sadashivrao Bhau increasingly adopted conventional warfare tactics, including the use of artillery and infantry trained by European mercenaries. This was an 'amendment' to their traditional military doctrine, aimed at confronting large, well-equipped armies like the Afghans and Mughals on open battlefields.	While demonstrating a willingness to adapt, this shift sometimes alienated their traditional cavalry-based strengths and proved disastrous at Panipat, where their conventional forces were outmaneuvered and outgunned by Abdali's superior artillery and cavalry.
