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. Technology flourished; there was investment in economic infrastructure, such as irrigation systems and canals; and the importance of reading the Quran produced a comparatively high level of literacy in the general populace.
In the 13th and 14th centuries, destructive Mongol invasions from the East, along with the loss of population in the Black Death, greatly weakened the traditional centers of the Islamic world, stretching from Persia to Egypt, but in the Early Modern period, the Ottomans, the Safavids, and the Mughals were able to create new world powers again.
