The Mughal Empire, founded by Babur, a direct descendant of Timur and Genghis Khan, was able to conquer almost the entirety of South Asia. Although religious tolerance was seen during the rule of emperor Akbar's, the reign under emperor Aurangzeb witnessed the full establishment of Islamic sharia and the re-introduction of Jizya (a special tax imposed upon non-Muslims) through the compilation of the Fatawa-e-Alamgiri. The Mughals, already suffering a gradual decline in the early 18th century, was invaded by the Afsharid ruler Nader Shah. The Mughal decline provided opportunities for the Maratha Empire, Sikh Empire, Mysore Kingdom, Nawabs of Bengal and Murshidabad and Nizams of Hyderabad to exercise control over large regions of the Indian subcontinent. Eventually, after numerous wars sapped its strength, the Mughal Empire was broken into smaller powers like Shia Nawab of Bengal, the Nawab of Awadh, the Nizam of Hyderabad, and the Kingdom of Mysore, which became the major Asian economic and military power on the Indian subcontinent.
