Trajan is one of Romeâs most outstanding emperors. Under his rule, the empire reached its largest extent.

Rome would add some areas, like modern Switzerland and Southern Scotland, but they would never amount to the size of the lands ruled by Trajan, Hadrian, Antoninus Pius, Marcus Aurelius and Commodus.hey were defeated many times by the Persians(Parthian and Sassanian Dynasties), but Persia never truly succeeded in conquering Rome since Persia was fighting many other empires and confederations and was invaded in the 7th century by the Muslims.
