What changed in the Mughal empire after the death of Jahangir ? Was Jahangir like the intolerant Aurangzeb, or was there an important difference between the two ?
John F Richards in his book ‘The Mughal Empire’ writes that Guru Arjan was not made a martyr because he was not a Muslim. He was killed because he had a popular following and was seen as a potential alternative centre of power in the Panjab.
Jahangir was a follower of a quietist Vaishnava ascetic, whose teachings were further removed from mainstream Islam than the teachings of Guru.
Shah Jahan and even more Aurangzeb were not interested in learning from, or recognising the value of the Dharmic traditions of the sub-continent. How religious they really were is difficult to tell, but they clearly were ‘politically’ more Islamic than Akbar and Jahangir.
Akbar promoted intermarriage with the Rajputs and other Indian elites. Whatever his other motives were, he realised that he could not even count on the support of all ‘Indian’ Muslims, and that he needed support from the Hindu ‘upper classes’ in order to survive. Jahangir continued this policy.
When under Shah Jahan and Aurangzeb this policy changed, it took away their most powerful tool to integrate new militant groups that confronted them. What you see under Aurangzeb is that members of the ruling Maratha Bhonsla family who joined the Mughals, almost always went back to their old allegiance, as they had no chance to become part of the Mughal ruling elites as the Rajputs became under Akbar.
The result was that every time the Mughals thought that they had the situation in the ‘Deccan’ under control and went back north, the insurrection in the south would flare up again. Unrest in the south created the opportunity to successfully rebel to Sikhs in the North West, Jats in what is now UP, various Nizams and Nawabs ruling as governors on behalf of the Mughal Patishah and formerly loyal Rajputs.
No government can rule if they do not have the respect of a substantial part of the population. Respect might be based on fear or on the expectation of rewards, under Aurangzeb non-Muslims lost their fear and got no rewards.
Under Aurangzeb the Mughal empire reached its greatest expansion, but he was the last of the great Mughals. After his death his successors, weakened by the constant wars, rapidly lost control over many of their territories. Aurangzeb died in 1807 and the Mughals carried on till 1857, but their Empire was gradually taken over by the East India Company.
