Gunpowder empiresThe gunpowder empires, or Islamic gunpowder empires, is a collective term coined by Marshall G. S. Hodgson and William H. McNeill at the University of Chicago, referring to three early modern Muslim empires: the Ottoman Empire, Safavid Empire and the Mughal Empire, in the period they flourished from mid-16th to the early 18th century. These three empires were among the most stable empires of the early modern period, leading to commercial expansion, and patronage of culture, while their political and legal institutions were consolidated with an increasing degree of centralization.
