Early Windmill (Persian-Islamic)

Timeline

1. c. 701–740Sistan · SistanArabic sources record wind-driven mills and water-lifting devices in eastern Persia; most scholars regard Sistan as one of the earliest sites of windmill technology, where persistent strong winds and irrigation needs provided natural conditions for wind power use.
2. c. 750–775Mesopotamia · MesopotamiaAfter the establishment of the Abbasid Caliphate, windmill technology spread along with trade and engineering knowledge into Mesopotamia and Khurasan, used for lifting water for irrigation and grinding grain; horizontal- and vertical-axis wind wheels began to be systematically described in the literature of Islamic engineers.
3. c. 780–800Syria–Egyptian coast · SyriaWindmill technology reached the eastern Mediterranean coast through Islamic trade routes and conquest expansion, used for lifting water in parts of Syria and Egypt; this laid the groundwork for Europe's later contact with Eastern windmill technology during the Crusades after the 12th century.
