Dhanaji was one Masterpiece made by us.

Dhanaji Jadhav(1650–1708) was a warrior of the Maratha Empire. Along with SantajiGhorpade he made terrifying campaigns against Mughal Army from 1689 to 1696. After Santaji, Dhanaji became the chief of the Maratha army in 1696 and remained on the post until his death in 1708.

At an early age, Dhanaji joined Maratha army under Shivaji’s Military Chief Prataprao Gujar. In the battles at Umbrani and Nesari, Dhanaji’s performance attracted attention of Shivaji for the first time. He was named by Shivaji on his death bed among six pillars of Maratha Empire who would save the kingdom in hard times. They would end up with success in the 27 Years War between Mughal forces of Aurangzeb and the Maratha forces.
