5) what did the western roman empire fall into?

Overexpansion and military overspending

At its height, the Roman Empire stretched from the Atlantic Ocean all the way to the Euphrates River in the Middle East, but its grandeur may have also been its downfall. With such a vast territory to govern, the empire faced an administrative and logistical nightmare. Even with their excellent road systems, the Romans were unable to communicate quickly or effectively enough to manage their holdings. Rome struggled to marshal enough troops and resources to defend its frontiers from local rebellions and outside attacks, and by the second century the Emperor Hadrian was forced to build his famous wall in Britain just to keep the enemy at bay. As more and more funds were funneled into the military upkeep of the empire, technological advancement slowed and Rome’s civil infrastructure fell into disrepair.
