The later Roman Empire shows that infrastructure includes administration, communications, and force organization as well as physical works. Earlier emperors had governed the same broad space, sometimes relying on officials and family members while campaigning elsewhere. Over time, systems that sent magistrates and officers from the center ceased to function reliably unless a powerful figure personally enforced decisions. Dividing authority among multiple Augustuses and Caesars therefore appears as a response to institutional breakdown rather than a sudden change in the empire's size.
