This volume is the first comprehensive study of the Polish history of law and Christianity written in English for a global audience. It examines the lives of twenty-one central figures in Polish law with a focus on how their Christian faith was a factor in molding the evolution of law in their country and the region. The individuals selected for study exhibit wide-ranging areas of expertise, from private law and codification, through national public law and constitutional law, to international developments that left their mark on Poland and the world. The chapters discuss the jurists within their historical, intellectual, and political context. The editors selected jurists after extensive consultation with legal historians looking at the jurists’ particular merits, contributions to law in general, religious perspective, and period under consideration. The collection will appeal to scholars, lawyers, and students interested in the interplay between law and religion. Political, social, legal, and religious historians, among other readers, will find, for the first time in English, authoritative treatments of essential Polish legal thinkers and authors.
