 As monasticism spread across Europe, Romanesque churches sprang up in Scotland, Scandinavia, Poland, Hungary, Sicily, Serbia and Tunisia.Several important Romanesque churches were built in the Crusader kingdoms.The system of monasticism in which the religious become members of an order, with common ties and a common rule, living in a mutually dependent community, rather than as a group of hermits living in proximity but essentially separate, was established by the monk Benedict in the 6th century.
