Rome, city, Italy: Augustus and the Pax Romana

Caesar's assassination brought anarchy, out of which the Second Triumvirate emerged with the rule of Octavian (later Augustus), Antony, and Lepidus. Octavian was Caesar's nephew, ward, and heir, and his true successor. At Actium (31 b.c.) he defeated Antony and Cleopatra and made the empire one. No change was made in the government, but Octavian received from the senate the title Augustus and from the people life tribuneship; this, with the governorship of all the provinces conferred by the senate, made him the real ruler. He was called imperator [commander] and princeps [leader] and is usually considered the first Roman emperor. (For a list of the Roman Emperors from Augustus to the fall of Rome and the years they reigned, see the table entitled Rulers of the Roman Empire.)

Augustus organized provincial government and the army, rebuilt Rome, and patronized the arts and letters. His rule began a long period (200 years) of peace, called the Pax Romana. During this time the Roman Empire was the largest it would ever be; its boundaries included Armenia, middle Mesopotamia, the Arabian desert, the Red Sea, Nubia, the Sahara, the Moroccan mountain mass, the Atlantic Ocean, the Irish Sea, Scotland, the North Sea, the Rhine, the Danube, the Black Sea, and the Caucasus. Augustus' chief additions to the empire were a strip along the North Sea W of the Elbe and part of the Danubian area.

The blessings of peace were great for the empire. The extensive system of Roman roads made transportation easier than it was again to be until the development of railroads. A postal service was developed closely tied in with the organization of the army. Commerce and industry were greatly developed, particularly by sea, over which grain ships carried food for Rome and the West from the ports of northern Africa. The Roman Empire became under Augustus one great nation. The enlarged view of the world made a great impression on Rome, where literary and artistic interests were of importance, although nearly always tending to imitation of Greece and of the East.

Augustus died a.d. 14 and was succeeded by his stepson Tiberius; his general Germanicus Caesar fought fruitlessly in Germany. Caligula, who followed, was a cruel tyrant (a.d. 37–a.d. 41); he was succeeded by Claudius I (a.d. 41–a.d. 54), who was dominated by his wives, but during his rule half of Britain was conquered (a.d. 43). In his time Thrace, Lydia, and Judaea were made Roman provinces. His stepson Nero (a.d. 54–a.d. 68) was an unparalleled tyrant. In his reign occurred the great fire of Rome (a.d. 64), attributed (probably falsely) to Nero; it burnt everything between the Caelian, the Palatine, and the Esquiline, but it was a boon to the city, for Nero moved the population to the right bank of the Tiber, then very thinly populated, and rebuilt the region with broader streets and great buildings.

At that time an entirely new element, Christianity, made itself felt in Rome. On Nero's orders a barbarous persecution took place in which many Christians died, among them St. Peter and St. Paul. Throughout the Roman Empire the Christians expanded steadily for the next centuries. Their conflict with the empire, which brought on them continual persecution, was chiefly a result of the Christian refusal to offer divine honors to the emperors. But Christianity penetrated the army and the royal household in spite of the constant danger of detection and persecution. There were many periods in the first three centuries when Christians worshiped openly, even in Rome, where the catacombs housed not only graves but also churches.

With Nero the Julio-Claudian line ended. There was a brief struggle (see Galba; Otho; Vitellius) before Vespasian (a.d. 69–a.d. 79) became emperor. Under him his son Titus destroyed Jerusalem (a.d. 70); Titus then briefly succeeded his father. After his mild, rather benign rule, his brother Domitian (a.d. 81–a.d. 96), a despot and persecutor of Christians, gained the empire. In Domitian's reign Agricola conquered Britain almost entirely. Domitian was unsuccessful in his dealings with the Daci and finally bought them off. After Nerva came Trajan (a.d. 98–a.d. 117), one of the greatest of emperors. Trajan undertook great public works, defeated the Daci and established Roman colonies there (in what is now modern Romania), and pushed the eastern borders past Armenia and Mesopotamia.

Trajan's successor, Hadrian, withdrew Roman rule to the Euphrates and in Britain built his wall (Hadrian's Wall) to hold back the barbarians who constantly threatened that fast-developing province. He also reorganized the senate and the army. Roman armies were then seldom seen far from the boundaries of the empire, and life continued throughout the Roman world in peace and quiet. Italy was sinking into a purely provincial state, although many emperors made attempts to make it a special country. The successors of Hadrian were Antoninus Pius (138–161) and Marcus Aurelius (161–180), who ruled in what is commonly called the Golden Age of the empire.
