Prior to the full rise of the Mughal Empire founded by Babur, one of the gunpowder empires, which annexed almost all of the ruling elites of the whole of South Asia, the Sur Empire ruled by Sher Shah Suri conquered large territories in the northern parts of India. Akbar gradually enlarged the Mughal Empire to include nearly all of South Asia, but the zenith was reached in the end of the 17th century, when the reign under emperor Aurangzeb witnessed the full establishment of Islamic sharia through the Fatawa-e-Alamgiri.
