Solution:The authority of Aurangzeb was challenged by Marathas for a long time.
Aurangzeb was the last efficient Mughal emperor. He was followed by the weak rulers, who the Britishers easily defeated. During the authority of Aurangzeb, the Maratha rulers greatly challenged him for an extended period. Aurangzeb had to encounter the hegemony of Shivaji in the last years of his rule. Campaigns were also made by Maratha cheese which is Shivaji against Aurangzeb. But later, Aurangzeb insulted Shivaji by not taking care of him when he invited Shivaji to his Court. This infuriated Shivaji, who declared himself an independent king, which further increased the vulnerability of the Mughal Empire under Aurangzeb.
