He could not tolerate as countrymen being oppressed under the tyranny of Muslim rule. So, he collected some chieftains, Jagirdars and others in order to free his countrymen from the oppression. He conquered the state of Bijapur and other Mughal territories. Aurangzeb could not tolerate this and he sent Shaista Khan to fight against him. Shivaji gave Shaista Khan a crushing defeat
Shivaji being a shrewd politician and an intelligent statesman proved more than a match for the tactics of Aurangzeb. Aurangzeb's attempt to imprison him failed. Shivaji also sensed the mischief of Afzal Khan and murdered him before he could attack Shivaji. Aurangzeb once made Shivaji a prisoner in Delhi, but the latter, with his intelligence thought of a plan and escaped from the prison with the help of the jail guards in a basket of sweets.
Shivaji will go down in Indian history as the defender and saviour of Hindu religion. He gave the enemies of Hindu religion a hard blow and established Marhatta Raj. But after his death in 1680, the entire citadel of Shivaji began to disintegrate because of the quarrels and conflicts among chiefs and jagirdars. But for Shivaji, Aurangzeb would have destroyed the entire Hindu religion. The entire Hindu community is proud of this valiant son of India whose deeds of chivalry and bravery have inspired the millions of Indian youths. Shivaji has become an immortal hero of history of India.
