This project focuses on processing and providing access to a database of census lists of Jews in Bohemia that were taken in the years 1723/1724–1811. This source of information is quite unique in character and is of major significance for the history of the Jews in Bohemia in the 18th century and early 19th century. It provides data concerning not only the nature Jewish settlement in the given period and the number of Jewish residents or familiants in each locality, but also to a large extent shows the structure, size and livelihoods of Jewish families, including information on contribution amounts levied, etc. Due to the fact that the list, in the relatively continuous way, cover the period from the 18th to the beginning of the 19th century, they make it possible, to a certain extent – not only in themselves, but also, and primarily, in comparison with other written sources – to record and monitor changes and trends in the life of the Jewish population in this period. They are important source of information for genealogists, researchers in the field of regional history, demographers and researchers in social and economic history.
