Dead horse, man-at-arms lost: cavalry and battle tactics in 15th century Castile

For a long time historiography has stood up for Late Medieval Castilian tactical backwardness with the insufficient research into Castilian military tactics contributing to the persistence of old paradigms. The aim of this paper is to refuse that vision by focusing on battle tactics showing the importance of mounted combat in fifteenth-century Castile. I will analyse the battlefield function of both heavy and light cavalries, also examining the supporting role of the infantry. This Castilian preference for mounted combat could be due to not only military reasons, but also social ones. In Castile, as in almost every corner of Medieval Western Europe, nobility's political and social leadership had its reflection on warfare.
