Canonized in 1297 as Saint Louis, King Louis IX of France (r. 1226–1270) was one of the most important kings of medieval history and also one of the foremost saints of the later Middle Ages. As a saint, Louis became the centerpiece of an ideological program that buttressed the ongoing political consolidation of France and underscored Capetian claims of sacred kingship.

M. Cecilia Gaposchkin reconstructs and analyzes the process that led to the monarch's canonization and the consolidation and spread of his cult. Differing political and religious ideals produced competing images of the sanctity of Louis in late-thirteenth and early ... Read morefourteenth-century France. Drawing on hagiography, sermons, and liturgical evidence—the latter a rich but little-explored historical source—Gaposchkin shows how various groups (including Dominicans, Cistercians, and Franciscans) and individuals (such as Philip the Fair and Joinville) used commemoration of the saint-king to sanctify their own politics and notions of identity and religious virtue. Louis' cult was disseminated to a wider, nonelite public through sermons in the fourteenth and fifteenth centuries and then revived by the Bourbon kings in the seventeenth century.

In deepening our knowledge of this royal saint, this elegantly written book opens the curtain on the religious sensibilities and secular politics of a transitional period in European history.
