From Wikipedia, the free encyclopedia
The 2nd century is the period from 101 - 200 in accordance with the Julian calendar in the Christian Era. It is considered part of the Classical era, epoch, or historical period
Early in the century, the Roman Empire attained its greatest expansion under the emperor Trajan, but after his death became primarily defensive for the rest of its history. Much prosperity took place throughout much of the second century, ruled as it was by the Five Good Emperors. The last quarter of the century saw the end of the period of peace and prosperity known as the Pax Romana at the death of the emperor Marcus Aurelius, last of the "Five Good Emperors", and the accession of his ineffective and allegedly deranged son Commodus.
