The Early Middle Ages, 284--1000 (HIST 210)In this lecture, Professor Freedman discusses the Abbasid dynasty, which ruled the Islamic Caliphate beginning in 750. The Abbasids moved the capitol of the Caliphate to the newly-built city of Baghdad and created a state characterized by a strong administration and well-organized tax system. The state sponsored a cultural flowering, based in part on the translation of classical Greek and Roman texts. Professor Freedman ends the lecture by focusing on developments in mathematics and astronomy. 00:00 - Chapter 1. The Rise of the Abbasids 15:47 - Chapter 2. Cultural Flowering28:28 - Chapter 3.
