Germania Sacra is a long-term research project ongoing at the Göttingen Academy of Sciences and Humanities. The project has a long-standing tradition of researching the history of dioceses, monasteries, collegiate churches, and convents within the Holy Roman Empire. The results of this work are published in reference books, the digital editions of these reference books along with two databases are the core components of Germania Sacra’s Online Portal. One of these databases is the ‘Digital Index of Persons’, which provides access to biographical and prosopographical information about the clerical staff affiliated to the institutions researched. This includes information about the bishops of a diocese, the canons or canonesses of individual collegiate churches, the monks and nuns of numerous monasteries, etc. The second primary feature of the online portal is the ‘Database of Monasteries, Collegiate Churches, and Convents of the Holy Roman Empire’.
