Regarded as a revisionist historian in the West, Patricia Crone, who wrote many books and articles on various subjects of early Islamic history, was a prolific researcher. The place and role of mawālī, in the Umayyad and Abbāsid society, has been one of the special topics she has been interested in since the very beginning of her academic life. Her works with a revisionist perspective have been faced many criticisms by colleagues, especially the western ones, because of her biased view (...) of the sources written by Muslim authors, her methodology, and her results. However, it is obvious that Crone’s studies on mawālī have positively or negatively affected the Eastern and Western academics in Islamic studies. This article’s main purpose is to reveal Crone’s views on mawālī in Isla-mic society and draw an outline without comment as much as possible. The paper consists of three parts. In the first part, Crone’s revisionist perspective and her works on mawālī have been explained. In the second part, her distinctive views on the mawālī and its origin have been discussed. Finally, in the third part, her findings of the position of mawālī in social, political, military, and economic life during the Rāshidun Caliphs, the Umayyads, and the Abbāsids have been introduced. This study, which tackles Crone’s views on mawālī, aims to encourage the further studies on this subject. (shrink)
