What the archives hold
For families with roots in the duchy, Mantua is unusually well served and unusually accessible.
The historical archive of the Jewish community, kept in rooms beside the synagogue, runs continuously from 1522 to the post-war period. It includes community minute books and correspondence, records of the confraternities and charitable institutions, the archive of the rabbinical court, and, most useful for family research, civil-status registers from 1750 to the present. The older section (1522–1853) has been digitised in partnership with Mantua's Biblioteca Teresiana: 42 vital-records registers, 75 volumes, dozens of parchments, and tens of thousands of loose documents from the community's filze are now viewable online. Roughly 230 filze still await digitisation, so a complete search still means the reading room.
The Archivio di Stato di Mantova holds the Gonzaga archive itself, the ducal privileges, banking licences (condotte), petitions, and court records in which Jewish families appear from the fourteenth century onward, along with the Napoleonic and Austrian civil registration that begins where the community's own records grow thin.
For the twentieth century, the CDEC in Milan holds the community's own report on the arrests of November 1943 and the individual records of the deported.
The standard scholarly guide to all of this is Shlomo Simonsohn's History of the Jews in the Duchy of Mantua (1977), which draws on the community archive in depth and remains the first book to open.
