This article is about the history of Islam as a culture and polity. For the history of the Islamic faith, see Islamic schools and branches.
The history of Islam concerns the political, economic, social, and cultural developments of the Islamic civilization.
Despite concerns about reliability of early sources, most historians believe that Islam originated in Mecca and Medina at the start of the 7th century. A century later, the Islamic empire extended from Iberia in the west to the Indus river in the east. Polities such as those ruled by the Umayyads (in the Middle East and later in Iberia), Abbasids, Fatimids, and Mamluks were among the most influential powers in the world. The Islamic civilization gave rise to many centers of culture and science and produced notable astronomers,mathematicians, doctors and philosophers during the Golden Age of Islam
