The Maratha Conquests were a series of conquests in the Indian subcontinent which led to the building of the Maratha Empire. These conquests were started by Shivaji in 1659 from the victory at the Battle of Pratapgad against Bijapur. The expansion of the empire was limited and interrupted by the Mughal conquests of south India by Emperor Aurangzeb. Marathas were forced to defend their territories against the overwhelmingly strong Mughal army in the 27 years long Deccan wars. They were able to defend their territories and gain an upper hand over Mughals in the sustained conflict.
