The peace between Shivaji and the Mughals lasted until 1670. At that time Aurangzeb became suspicious of the close ties between Shivaji and Mu'azzam, who he thought might usurp his throne, and may even have been receiving bribes from Shivaji. Also at that time, Aurangzeb, occupied in fighting the Afghans, greatly reduced his army in the Deccan; many of the disbanded soldiers quickly joined Maratha service. The Mughals also took away the jagir of Berar from Shivaji to recover the money lent to him a few years earlier. In response, Shivaji launched an offensive against the Mughals and recovered a major portion of the territories surrendered to them in a span of four months.
