While most citizens of the world were living in huts and eating wild animals and such, the city of Rome was already dealing with building height regulations (buildings had to be limited to six floors), traffic jams, and problems with indoor plumbing.
The Romans were way ahead of their time. While most citizens of the world were living in huts and eating wild animals and such, the city of Rome was already dealing with building height regulations (buildings had to be limited to six floors), traffic jams, and problems with indoor plumbing. Instead of a feudal-like society found elsewhere in the world, where you would die in the same status you were born in, you could be a simple soldier in Rome and become a senator, or a simple baker and become filthy rich. You could live in modern-day Spain, Egypt, or Bulgaria and still be a Roman citizen.
