Medieval dynasties relied frequently upon the cult of royal saints for legitimacy, and in the central middle ages most royal dynasties included saints in their family. Within this context, the saints of the Hungarian ruling dynasty constitute a remarkable sequence, and provide a unique example of the late medieval evolution of royal and dynastic sainthood. Building upon a series of case studies from Hungary and central Europe, Gá bor Klaniczay proposes an original new synthesis of the multiple forms and transformations of royal and dynastic sainthood.
