The study analyses the long term of the ties between southern Bohemia and Upper Austria in several social and cultural environments beginning from the cross-border colonization of the early and high medieval Benedictine, Cistercian and Premonsterian monasteries in the research region and the cults of saints and pilgrimages promoted by them, over the underground networks of the Waldenses and other heretics in the 14. and 15. century until to the long term resonance of the husitism in the social rebellions and peasant wars in Upper Austria.
