This second collection of articles by Patricia Crone brings together studies on the development of early Muslim society, above all the army with which it was originally synonymous, from shortly after the Prophet's death until the mid-Abbasid period. The focus is on the changes that the Arab tribesmen underwent thanks to settlement outside Arabia, their strained relations with converts from the conquered population, and their gradual eclipse by them.
Patricia Crone was Professor Emerita in the School of Historical Studies, where she served as the Andrew W. Mellon Professor from 1997 until her retirement in 2014. Crone’s insightful work, compellingly conveyed in her adventurous and unconventional style, shed important new light on the critical importance of the Near East—in particular on the cultural, religious and intellectual history of Islam—in historical studies. Her influence is strongly felt at the Institute, where, along with Oleg Grabar (1929–2011), Crone helped to establish the Institute as a recognized center for the pursuit of the study of Islamic culture and history.
Probably more detailed than necessary unless you're really into early Islamic history or theories on tribes. The rest of us can learn from how Crone applies her particular brand of source-critical historical analysis.
