This study focuses on the research of watermarks contained in nine municipal registers of the feudal towns Boskovice and Letovice during the early modern age (more specifically the years 1484–1761). Seven books belong to Boskovice and two to Letovice; and they contain a total of 20 types of surviving watermarks. Besides their description, the study includes general comparison in the area of the watermarks' research, paper mill identification, a table with conlusions and an appendix with images.
The study deals with the evolution of religious situation in the feudal town Boskovice and a local estate there before the time of the Battle of White Mountain in 1620. It also describes the religion of local nobility in the context of political history, reformation and other non-Catholic religious movements. The main source of information are the municipal administration records which provide data about sacral buildings, priests, administration of church fabrics and burgher testaments.
