What did the Romans contribute to society?

After the fall of the Roman empire, it took a thousand years for Europe to start flourishing again. F0r 1000 years, there were almost no art and literature in Europe and Europe entered what was called the Middle Ages, or Dark Ages. The Roman empire provided a form of stability and protection for Europe. This meant that during the Roman empire, Europe understood what was the position of everyone and had stability. Everyone understood what their job was and what was expected of them. They knew that they had to give a certain amount of their crops to the Romans and that they had a set of laws that they had to follow or be punished. The Romans also provided protection for Europe. The romans also ensured that none of the barbaric tribes attacked any of the towns and cities that were under their control. The barbaric tribes knew that they would be massacred if they dared attack the cities. After the fall of the roman empire all of this changed. Towns and cities were no longer protected by the soldiers and were continuously pillaged by rogue knights and mercenaries. Europe also did not have any of form of stability and it was a free for all. It was impossible to travel through trading routes without being attacked by bandits. People could kill each other for no reason and get away with it. It took 400 years for Europe to finally get a form of stability back and stop people from being continuously robbed.
