I conti di Galeria (secoli XI–XIII)

The Counts of Galeria, prominent in Roman politics from the early 11th to the mid-13th century, played a pivotal role during the papacies of Benedict IX and Benedict X. Graf Gerardo I, a key figure, held significant influence in Rome and southern Tuscany, collaborating closely with popes and the Abbots of Farfa while overseeing multiple castles. His brother, Graf Sassone of Civita Castellana, and their descendants maintained control over Civita Castellana until the late 11th century. The study reveals that the Gallery Castle likely reverted to papal ownership after Gerardo I's death, as documented in archives from San Paolo fuori le Mura. While other Counts of Galeria emerged sporadically in the 12th and 13th centuries, none matched the prominence of Gerardo I and Sassone. This research reconstructs the political dynamics of the period through archival sources, highlighting the Counts' role in shaping Roman and Tuscan governance.
