Stretch above is one of the most interesting maps of the Roman Empire ever made, all carted in detail using modern computational techniques. It shows what the great empire used to look like during its period of maximum expansion under the reign of Septimius Severus, about 211 CE. As you can notice, the Romans’ domain covered much of Europe, from the Atlantic to the Ural Mountains and from modern day Scotland to the Sahara or the Arabian Golf.
At the height of imperial power, Rome called 55 to 60 million people its own – that’s if you count the women, slaves and other classes of people under Roman rule who weren’t considered citizens. In total that’s 15% of the world’s population at the time. Most of the population of the Roman Empire lived within easy reach of the Mediterranean, and the imperial government promoted and protected sea-trade and naval communications between the various parts of the empire. The map made by Sardis Verlag, a publishing house in Germany, elegantly illustrates some of the most used sea trade routes. Not incidentally, they all join at some point with Rome. Although it could be relatively dangerous, sea-transport was much faster and much less effecting that over-land carriage. There had been sea-borne commercial empires in the Mediterranean Sea for well over two thousand years before Roman domination. The Romans worked to keep the sea clear of pirates, to build lighthouses and to construct large and sheltered harbors for the great commercial cities maintained by that trade. One might go so far as to say that the existence of the Roman empire depended on the unity of the Mediterranean or, as the Romans called it, Mare nostrum, “Our Sea.”
After Septimius Severus died, all four emperors that followed were assassinated. Rome at the time became a monster too big for its own good. Corruption had eroded the empire and it would culminate with the Crisis of the Third Century, which saw the empire almost obliterated at hand of civil war and foreign invaders.
