Byzantine Empire under the Justinian dynasty

The Byzantine Empire under the Justinian dynasty began in 518 AD with the accession of Justin I. Under the Justinian dynasty, particularly the reign of Justinian I, the empire reached its greatest territorial extent since the fall of its Western counterpart, reincorporating North Africa, southern Illyria, southern Spain, and Italy into the empire. The Justinian dynasty ended in 602 with the deposition of Maurice and the accession of his successor, Phocas.
