Jahangir, Shah Jahan and Aurangzeb — Key Changes

Entry	Year	Description	Impact
N/A (Policy Shift)	1606	Jahangir's execution of Guru Arjan Dev, the fifth Sikh Guru, marked a significant shift in Mughal policy towards the Sikh community. While not a formal administrative 'amendment,' it represented a departure from Akbar's general policy of religious tolerance and had profound implications for future Sikh-Mughal relations.	Escalated tensions between the Sikh community and the Mughal state, contributing to the eventual militarization of the Sikhs under later Gurus.
N/A (Policy Shift)	1679	Aurangzeb's re-imposition of the Jizya tax on non-Muslims, which had been abolished by Akbar, was a major policy reversal. This move was part of his broader effort to govern according to Islamic law and assert an orthodox Islamic identity for the empire.	Caused widespread resentment among the non-Muslim population, particularly Hindus, and contributed to the breakdown of traditional alliances (e.g., with Rajputs) and fueled various revolts against Mughal authority.
N/A (Administrative Change)	1660s onwards	The increasing strain on the Jagirdari system, leading to the 'Jagirdari crisis,' was not a formal amendment but a critical administrative development. The number of Mansabdars grew rapidly, outstripping the available revenue-yielding lands (jagirs), leading to a shortage of jagirs and frequent transfers.	Resulted in administrative inefficiency, corruption, exploitation of peasants, and a weakening of the loyalty and effectiveness of the Mughal nobility, contributing to the overall decline of the empire.
