The seminal work of Karlheinz Deschner in a 10-volume series covering the period from the end of antiquity to the 12th century.

In the Criminal History of Christianity, crimes that have been committed beyond institutional and religious barriers are recorded, spanning the entire spectrum of state, ecclesiastical, and social life of Christendom.

The historical description includes the consistent connection between so-called secular and ecclesiastical power, as well as the consequences of this connection for the peoples: criminality in foreign policy as well as in agricultural, commercial, and economic life, the spread of ignorance and superstition, interventions in education and culture, censorship, exploitation of sexual morality, marital and criminal law.
