This study examines the religious composition of the population on so-called state estates, which included estates administered by an official body, but also by the Religious, Study and Endowment Fund, or Charles-Ferdinand University. The research is based on a survey event that took place on the estates in 1802. Analyses revealed that a majority Catholic population lived on the estate. This was particularly typical of western Bohemia. Conversely, the Protestant tradition was confirmed in the eastern Bohemian estates, especially Podebrady and Pardubice, and also the estates of Vetrny Jenikov and Stredokluky. While on the estates of Pardubice and Vetrny Jenikov Protestants were concentrated in particular areas, in Podebrady the co-existence of Catholics and Helvetians was quite common. With regard to the Jewish population, unlike the Protestants there were Jews living in most of the state estates, but the proportion of the population they represented was much lower, around less than 1%, and it was more a matter of individual families.
