Roman Empire (1st Century BC To 5th Century AD)

Determining the precise end of the Republic is a task of dispute by modern historians; Roman citizens of the time did not recognize that the Republic had ceased to exist. The early Julio-Claudian "Emperors" maintained that the res publica still existed, albeit under the protection of their extraordinary powers, and would eventually return to its full Republican form. The Roman state continued to call itself a res publica as long as it continued to use Latin as its official language.

Rome acquired imperial character de facto from the 130s BC with the acquisition of Cisalpine Gaul, Illyria, Greece and Hispania, and definitely with the addition of Iudaea, Asia Minor and Gaul in the 1st century BC. At the time of the empire's maximal extension under Trajan (AD 117), Rome controlled the entire Mediterranean as well as Gaul, parts of Germania and Britannia, the Balkans, Dacia, Asia Minor, the Caucasus and Mesopotamia.

Culturally, the Roman Empire was significantly hellenized, but also saw the rise of syncratic "eastern" traditions, such as Mithraism, Gnosticism, and most notably Christianity. The empire began to decline in the crisis of the third century
