Book excerpt: In the late fourteenth century, the medieval Crown of Aragon experienced a series of food crises that created conflict and led to widespread starvation. Adam Franklin-Lyons applies contemporary understandings of complex human disasters, vulnerability, and resilience to explain how these famines occurred and to describe more accurately who suffered and why. Shortage and Famine in the Late Medieval Crown of Aragon details the social causes and responses to three events of varying magnitude that struck the western Mediterranean: the minor food shortage of 1372, the serious but short-lived crisis of 1384–85, and the major famine of 1374–76, the worst famine of the century in the region. Shifts in military action, international competition, and violent attempts to control trade routes created systemic panic and widespread starvation—which in turn influenced decades of economic policy, social practices, and even the course of geopolitical conflicts, such as the War of the Two Pedros and the papal schism in Italy. Providing new insights into the intersecting factors that led to famine in the fourteenth-century Mediterranean, this deeply researched, convincingly argued book presents tools and models that are broadly applicable to any historical study of vulnerabilities in the human food supply. It will be of interest to scholars of medieval Iberia and the medieval Mediterranean as well as to historians of food and of economics.
