Traditional explanations for Byzantine iconoclasm have sometimes focused on the importance of Islamic prohibitions against images influencing Byzantine thought. According to Arnold J. Toynbee, for example, it was the prestige of Islamic military successes in the 7th and 8th centuries that motivated Byzantine Christians to adopt the Islamic position of rejecting and destroying devotional and liturgical images. The role of women and monks in supporting the veneration of images has also been asserted. Social and class-based arguments have been put forward, such as that iconoclasm created political and economic divisions in Byzantine society; that it was generally supported by the Eastern, poorer, non-Greek peoples of the Empire who had to constantly deal with Arab raids. On the other hand, the wealthier Greeks of Constantinople and also the peoples of the Balkan and Italian provinces strongly opposed Iconoclasm. Re-evaluation of the written and material evidence relating to the period of Byzantine Iconoclasm by scholars including John Haldon and Leslie Brubaker has challenged many of the basic assumptions and factual assertions of the traditional account.
