Soyarabai
Shivaji died in 1680 at his capital without naming any successor. In order to continue the empire, Soyarabai got her ten-year-old son, Rajaram as the only legal successor to the throne. But her stepson and heir presumptive Sambhaji, was able to stop this. They took help from Soyrabai's own brother, army chief Hambirrao Mohite and put Soyarabai and Rajaram in prison. They took the full power and Sambhaji became the Chhatrapati on 20 July 1680.
