In this hitherto unpublished treatise, Hugo Grotius examines what kinds of partnerships between Christians and non-Christians are legally permissible. These include public partnerships, such as treaties and alliances, but also private associations, such as commercial contracts, marriages, and relations of servitude. Grotiusâs treatise is indispensable for understanding his ideas about legal relations between Christians and non-Christians, both in international and domestic contexts. This is the first edition of the annotated Latin text with an English translation and introduction.
