In which year did the reign of this emperor, who convoked the Second Council of Constantinople, end?
Justinian I Justinian I ( ; Latin: "Flavius Petrus Sabbatius Iustinianus Augustus" ; Greek: Φλάβιος Πέτρος Σαββάτιος Ἰουστινιανός "Flávios Pétros Sabbátios Ioustinianós" ) ( 482 14 November 565), traditionally known as Justinian the Great and also Saint Justinian the Great in the Eastern Orthodox Church, was the Byzantine (East Roman) emperor from 527 to 565. During his reign, Justinian sought to revive the empire's greatness and reconquer the lost western half of the historical Roman Empire. Justinian's rule constitutes a distinct epoch in the history of the Later Roman empire, and his reign is marked by the ambitious but only partly realized "renovatio imperii", or "restoration of the Empire".
Flavian dynasty The Flavian dynasty was a Roman imperial dynasty, which ruled the Roman Empire between 69 AD and 96 AD, encompassing the reigns of Vespasian (69–79), and his two sons Titus (79–81) and Domitian (81–96). The Flavians rose to power during the civil war of 69, known as the Year of the Four Emperors. After Galba and Otho died in quick succession, Vitellius became emperor in mid 69. His claim to the throne was quickly challenged by legions stationed in the Eastern provinces, who declared their commander Vespasian emperor in his place. The Second Battle of Bedriacum tilted the balance decisively in favour of the Flavian forces, who entered Rome on December 20. The following day, the Roman Senate officially declared Vespasian emperor of the Roman Empire, thus commencing the Flavian dynasty. Although the dynasty proved to be short-lived, several significant historic, economic and military events took place during their reign.
