The Roman empire existed in some form or another for the better part of 1000 years. Much like the United States, the reason Rome became so big and powerful is because it accepted everyone. Eventually through war, technology and culture it spread to cover most of the known world.
In some ways the Romans were barbaric, such as slavery and blood sport. But in most other ways they were pretty advanced. They developed some of the first long lasting concrete and paved roads that spread for miles and miles. They build aqua ducts that brought water into the city and sewer systems. As a result they had running water, bath houses and fountains. They considered cleanliness and proper grooming a necessity.
In a nutshell, they did a lot of things that were very technological and progressive.
After the Roman Empire fell, the known world went into the dark ages. It would take us nearly 1000 years later before the known world began to rediscover these things the Romans had been doing.
It’s really been within the last 300-500 years that we’ve been heavily advancing. The last 150 years that things have really really taken off and now we’ve got ourselves moving in good stride.
So what changed? Why is it that the Roman empire that was around for roughly 1000 years never got to the technological level that we currently possess?
