The Roman Empire created a successful political and military structure despite facing disastrous defeats and loss of troops. Their military reputation was distinguished by their ability to win wars despite losing all of their soldiers, and they had a sophisticated communication network similar to Twitter through their use of graffiti.
The discovery of Roman graffiti in Pompeii is a fascinating aspect of history. It gives insight into the lives of ancient Romans and their culture, particularly in regards to sexuality and violence.

The Romans created a political structure that was able to survive even in times of disastrous military defeats. The ruling class, along with the middle and rich classes, were the ones who actively participated in wars.
