For any fan of history or of Ancient Rome, our infographic map of the Roman Empire probably looks familiar. It shows the maximum territorial extent ever achieved by the Roman Empire, just after Trajan’s ambitious wars in the East, during which he captured Dacia (Romania), Armenia, Mesopotamia, Assyria, and the Parthian capital of Ctesiphon (in modern-day Iraq).
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.
