Shivaji I (Shivaji Shahaji Bhonsale, Marathi pronunciation: [ʃiˈʋaːdʑiː ˈbʱos(ə)le]; c. 19 February 1630 – 3 April 1680) was an Indian ruler and a member of the Bhonsle dynasty. Shivaji inherited a jagir from his father who served as a retainer for the Sultanate of Bijapur, which later formed the genesis of the Maratha Kingdom. In 1674, he was formally crowned the Chhatrapati of his realm at Raigad Fort.
Shivaji offered passage and his service to the Mughal emperor Aurangzeb to invade the declining Sultanate of Bijapur. After Aurangzeb's departure for the north due to a war of succession, Shivaji conquered territories ceded by Bijapur in the name of the Mughals. Following his defeat at the hands of Jai Singh I in the Battle of Purandar, Shivaji entered into vassalage with the Mughal empire, assuming the role of a Mughal chief, during this time Shivaji also wrote a series of letters apologising to Mughal emperor Aurangzeb for his actions and requested additional honors for his services. He was later conferred with the title of Raja by the emperor. He undertook military expeditions on behalf of the Mughal Empire for a brief duration.
