Byzantine Empire - Origin

Caracalla's decree in 212, the Constitutio Antoniniana, extended citizenship outside of Italy to all free adult males in the entire Roman Empire, effectively raising provincial populations to equal status with the city of Rome itself. The importance of this decree is historical rather than political. It set the basis for integration where the economic and judicial mechanisms of the state could be applied around the entire Mediterranean as was once done from Latium into all of Italy. Of course, integration did not take place uniformly. Societies already integrated with Rome such as Greece were favored by this decree, compared with those far away, too poor or just too alien such as Britain, Palestine or Egypt.

The division of the Empire began with the Tetrarchy (quadrumvirate) in the late 3rd century with Emperor Diocletian, as an institution intended to more efficiently control the vast Roman Empire. He split the Empire in half, with two emperors (Augusti) ruling from Italy and Greece, each having as co-emperor a younger colleague of their own (Caesares). After Diocletian's voluntary abandonment of the throne, the Tetrarchic system began soon to crumble: the division continued in some form into the 4th century until 324 when Constantine the Great killed his last rival and became the sole emperor. Constantine decided to found a new capital for himself and chose Byzantium for that purpose. The rebuilding process was completed in 330.

Constantine renamed the city Nova Roma, but the populace would commonly call it Constantinople (in Greek, Κωνσταντινούπολις, Constantinoúpolis, meaning Constantine's City). This new capital became the centre of his administration. Constantine deprived the single preatorian prefect of his civil functions, introducing regional prefects with civil authority. During the 4th century, four great "regional prefectures" were also created.

Constantine was also probably the first Christian emperor. The religion, which had been persecuted under Diocletian, became a "permitted religion" and steadily increased its power as years passed, apart from a short-lived return to pagan predominance under the emperor Julian. Although the empire was not yet "Byzantine" under Constantine, Christianity would become one of the defining characteristics of the Byzantine Empire, as opposed to the pagan Roman Empire.

Constantine also introduced a new stable gold coin, the solidus, which was to become the standard coin for centuries, and not only in the Byzantine Empire.

Another defining moment in the history of the Roman/Byzantine Empire was the Battle of Adrianople in 378 in which the Emperor Valens and the best of the remaining Roman legions were killed by the Visigoths. This defeat has been proposed by some authorities as one possible date for dividing the ancient and medieval worlds. The Roman Empire was divided further by Valens' successor Theodosius I (also called "the Great"), who had ruled both parts since 392: following the dynastic principle well established by Constantine, in 395 Theodosius gave the two halves to his two sons Arcadius and Honorius; Arcadius became ruler of the eastern half, with his capital in Constantinople, and Honorius became ruler of the western half, with his capital in Ravenna. Theodosius was the last Roman emperor whose authority covered the entire traditional extent of the Roman Empire. At this point, it is common to refer to the empire as "Eastern Roman" rather than "Byzantine."
