This work deals with the reign of Pedro I of Castile (1350-1369), known as “The Cruel,” one of the most notorious and misunderstood figures in the annals of peninsular history. This is the first book on the subject that analyzes Pedro's rule in light of social, political, diplomatic, and economic conditions in mid-14th century Castile. Using extant primary documentation from archival sources and the most recent findings of scholars from various fields, the book explores in detail the historical basis for Pedro's reputation and the extent to which this reputation unfairly rests on the testimony of Pero López de Ayala, the reign's principal chronicler. The book provides fresh insights into various aspects of Pedro's career, such as his political aims, relations with religious minorities, and fiscal policies.

This is the second update of "A Cumulative Bibliography of Medieval Military History and Technology," which appeared in 2002. It is meant to do two things: to present references to works on medieval military history and technology not included in the first two volumes; and to present references to all books and articles published on medieval military history and technology from 2003 to 2006. These references are divided into the same categories as in the first two volumes and cover a chronological period of the same length, from late antiquity to 1648, again in order to present a more complete picture of influences on and from the Middle Ages. It also continues to cover the same geographical area as the first and second volume, in essence Europe and the Middle East, or, again, influences on and from this area. The languages of these bibliographical references reflect this geography.
