In Between Popes, Inquisitors and Princes Jessica Dalton uses extensive, original archival research to provide the first history of a unique and controversial papal privilege that allowed the first Jesuits to absolve heretics in sixteenth-century Italy without involving bishops or inquisitors. Dalton uses the story of this remarkable privilege to reconsider two central aspects of Jesuit history: their role in the Counter-Reformation and their relationship with the papacy. She convincingly argues that, in the aftermath of the Protestant Reformation, the Jesuits were valued collaborators of popes, inquisitors and princes not for their obedience and subservience but rather because they worked with an autonomy and flexibility that allowed them to convert heretics where political barriers and popular hostility hindered inquisitors and prelates.

The papacy has often resembled a secular European monarchy more than a divinely inspired institution. Roman pontiffs bestowed great wealth on their families and forged strategic alliances with other powerful families to increase their power. Pope Alexander VI (Rodrigo Borgia), for example, forced his daughter Lucrezia into a series of marriages for political reasons. When her marital alliance was no longer advantageous, as was the case in her second marriage, her husband was brutally murdered. Many papal families also intermarried in hopes of forming a hereditary papacy; at least two members of the Fieschi, Piccolomini, Della Rovere, and Medici families served as pope. Papal families since the early history of the church are fully covered in this comprehensive work. Genealogical charts graphically show the descendants of the popes, presenting in many cases the interrelationships between the papal families and their relationships with many of the leading families of Europe. Detailed histories examine the impact of the papacy on each pope's family and how each influenced the history of the church.

This study reinterprets the relationship between the medieval papacy and independent states, suggesting that kings and governments were able to increase their effective power through close relationships with the international papacy, making the papacy integral to the creation of centralized national states and kingdoms in Europe.
