The first attempt to collect and publish the history of the German dioceses in reference books was made by Martin Gerbert, the prince-abbot of the monastery St. Blasien in the late 18th century, but his works were never completed.
Following into Gerberts footsteps, Paul Fridolin Kehr established a new Germania Sacra under the patronage of the Kaiser-Wilhelm-Society at the Kaiser-Wilhelm-Institute of German History in Berlin in 1917.
He tried to connect the nationwide research projects and combine them under Germania Sacra to create an archival collection of monasteries, convents, cathedral chapters and religious dignitaries.
[2] The main objective of Germania Sacra is a statistical description of the ecclesiastical institutions which existed between the Holy Roman Empire and German mediatisation in the early 19th century.
