It is most extremely unlikely that a tribe (which by definition is not a big social group) would build thousands of miles of roads. It takes an empire to build thousands of miles of roads. This empire was the vast Roman Empire, which was the second largest empire antiquity saw and was and the 17th largest in history. The Romans built 400,000 kilometres (250,000 miles) or roads throughout the Roman Empire. Of these, 20% (80,500 kilometres, 50,313 miles) were the famous stone-paved roads. Of course, most of these roads did not go to Rome, the capital of the empire. Not surprisingly, the roads which went directly to Rome were in Italy. There were nineteen of them. Many of these had only a regional reach.
