Being hostile to dogma, Socinians insisted that Christian doctrine must be compatible with reason and advocated freedom of conscience, guaranteed by the separation of church and state.
Their intellectual centre was in Raków, north of Kraków, where they founded a successful university and a famous printing operation that turned out many Socinian books and pamphlets distributed all over Europe.
Many historians consider them to be the forerunners of the European Enlightenment and the main inspiration of American constitution.
