Notitia Dignitatum

The Notitia Dignitatum is a historical document from the late Roman Empire, dating around the early 5th century. It serves as an administrative and military directory, listing the officials, military units, and civil authorities across the empire. Essentially, it functions like an organizational chart, detailing who was responsible for various regions and military commands, providing insight into the structure and governance of the Roman Empire during its decline. The document helps historians understand how the empire was organized and maintained its defenses during a turbulent period.
