Madhavrao I
After the death of Madhavrao I in 1772, his brother Narayan Rao became Peshwa of the Maratha Empire. Narayan Rao was the fifth Peshwa of the Maratha Empire from November 1772 until his murder by his palace guards in August 1773. Narayan Rao's widow, Gangabai, gave birth to a posthumous son, who was legal heir to the throne. The newborn infant was named Sawai Madhavrao. Twelve Maratha chiefs, led by Nana Fadnavis, directed an effort to name the infant as the new Peshwa and rule under him as regents.
