What did Ancient Rome look like at its peak in 117 AD?
The map below from Visual Capitalist shows the maximum territorial extent ever achieved by the Roman Empire, just after their successful wars in the east, where Emperor Trajan captured Dacia (Romania), Armenia, Mesopotamia, Assyria, and the Parthian capital of Ctesiphon (in modern-day Iraq).

As Visual Capitalist explains further, although Trajan is rated as one of the best Roman Emperors by historians and was considered one of the strongest military leaders in Roman history, the reality is that the peak he achieved was very short-lived.
We’ll dig into that and more as we explain this map, which covers one of the most interesting periods in history, leveraging classical and modern sources including Cassius Dio, Plutarch, Cambridge Ancient History, Walter Scheidel, Fergus Millar, Adrian Goldsworthy, Anthony Everitt, and Encyclopaedia Britannica.
Trajan: The First Emperor Born Outside of Italy
Trajan was born in Italica, Spain, near modern-day Seville. He was a career soldier and became an extremely competent and respected general. He was adopted as the heir to the childless Nerva, and became emperor after Nerva’s passing in 98 AD.

I’m afraid the United States may have already peaked, but we have one last hope to save this great county. That bullet didn’t take his head off for a reason. Everyone please pray for President Trump. That man risked going to prison for this country and now his life again.
