Did the roman empire gain a good deal of new territory?

Yes, the Roman Empire significantly expanded its territory throughout its history, particularly during the Republic and early Empire periods. Key conquests included regions such as Gaul, Hispania, North Africa, and parts of the Middle East. The empire reached its greatest territorial extent under Emperor Trajan in the early 2nd century AD. This expansion facilitated the spread of Roman culture, trade, and governance across vast regions of Europe, North Africa, and the Near East.
