Final answer:
The Mughal Empire's reversal of religious tolerance policies occurred under the rule of Emperor Aurangzeb, who was less inclusive than his predecessor Akbar and actively discriminated against non-Muslims.
Step-by-step explanation:
The Mughal Empire reversed its policies of religious tolerance during the rule of Emperor Aurangzeb. Emperor Akbar, who ruled from 1556 to 1605, was known for his religious tolerance and even attempted to create a syncretic state religion by amalgamating different faiths. However, his policies changed under the rule of his great-grandson Aurangzeb, who was less tolerant and imposed a tax on non-Muslims and destroyed the temples of Hindus who resisted his rule. Aurangzeb also executed the Sikh guru Tegh Bahadur, highlighting his staunch position against religious freedom, which contrasts sharply with the tolerant and inclusive policies of Akbar.
