A tale of two port cities : Al-Mahdiyya, Palermo, and the timber trade of the medieval Mediterranean

Although the timber trade was essential in the tenth century to the global ambitions of the North African Fatimid Caliphate, environmental and political obstacles compelled the Fatimids to obtain most of their precious cargo from Sicily. This article discusses timber's essential importance to the Fatimids and how they procured this commodity, shedding light on the historical developments that occurred at the ports of al-Mahdiyya and Palermo under the Fatimids as a result of continuous trade between Ifrīqiya and Sicily. Applying a multidisciplinary analysis of Fatimid chancellery documents, historical texts, material culture, environmental history, and history of art, this article considers the role of the timber trade in the urban development of these two port cities. Specifically, it looks closely at the direct role of Ustādh Jūdhar, a tenth-century Fatimid official, in the procurement of timber. The result is a nuanced picture of the complexities of trade in the medieval Islamic Mediterranean world.
