Socinianism has often been studied in national contexts and apart from other currents like Arminianism. This volume is especially interested in the "in-betweens": the relationship of Anti-trinitarianism to "liberal" currents in reformed Protestantism, namely Dutch Remonstrants, English Latitudinarians and some French Huguenots. This in-between also has a local aspect: the volume studies the transformations that Antitrinitarianism experienced in the complicated transition from its origins in Italy and its refuge in Poland, Moravia and Transsylvania to Prussia, to the Netherlands and later to England. What effects did this transfer have on the dynamics of pluralization in the progressive Netherlands? How did the Socinians overcome social adaptation from a group of exiles to a diffuse movement of modernization? How did they manage to connect within the new milieu of Arminians, Cartesians, Spinozists and Lockeans?
