The study summarizes the development of ecclesiastical organizations in the Czech lands before 1200, taking into account the wider European context. The author first draws attention to the difficulties associated with the number and character of the preserved sources. Then he problematizes the traditional notion of ecclesiastical dignitaries as mere servants of the duke, confronting the question of tithes and examining evidence of the activity of the archdeacons and archpriests. In conclusion, he focuses on the question of building the parish organization and subscribes to the notion that this was not a centrally controlled activity, but rather a local initiative, although supported by the bishop. and David Kalhous.
