Dynasty Justinian Dynasty

Justin I (Latin : Flavius Iustinus; Greek : Ἰουστῖνος, Ioustînos; 2 February 450 – 1 August 527) was the Byzantine emperor from 518 to 527. He rose through the ranks of the army to become commander of the imperial guard, and when Emperor Anastasius died he out-maneouvered his rivals and was elected as his successor, in spite of being almost 70 years old. His reign is significant for the founding of the Justinian dynasty that included his eminent nephew Justinian I and three succeeding emperors. His consort was Empress Euphemia.


He was noted for his strongly orthodox Christian views. This facilitated the ending of the Acacian schism between the churches of Rome and Constantinople, resulting in good relations between Justin and the papacy. Throughout his reign he stressed the religious nature of his office and passed edicts against various Christian groups seen at the time as non-Orthodox. In foreign affairs he used religion as an instrument of state. He endeavoured to cultivate client states on the borders of the Empire, and avoided any significant warfare until late in his reign.

Early career

Justin was a peasant and possibly a swineherd by occupation, [2] from the region of Dardania, part of the Prefecture of Illyricum. [3] He was born in the hamlet Baderiana near Scupi (modern Skopje, North Macedonia). [2] He was of Thraco-Roman [4] [5] or Illyro-Roman descent, [6] [7] [8] spoke Latin and only rudimentary Greek, and bore, like his companions and members of his family (Zimarchus, Dityvistus, Boraides, Bigleniza, Sabbatius, etc.), a Illyro-Thracian name. [6] [9] His sister Vigilantia (born c.455) married Sabbatius and had two children: the future emperor Petrus Sabbatius Justinianus (born 483) and Vigilantia (born c. 490). The younger Vigilantia married Dulcissimus (or Dulcidio) and had at least three children: the future emperor Justin II (born c. 520); the future general Marcellus; and Praejecta (born c. 520), who married the senator Areobindus. [10]

As a teenager, he and two companions fled from a barbarian invasion. Taking refuge in Constantinople, the capital of the Eastern Roman Empire, they possessed nothing more than the ragged clothes on their backs and a sack of bread among them. [11] Illiterate at the time of his arrival there, [11] Justin joined the newly formed palace guard, the excubitors . He served in various positions, campaigning against the Isaurians and the Sassanian Persians and was noticed for his bravery. Because of his ability he was successively appointed a tribune, a comes , a senator and, under the Emperor Anastasius I, the influential position of comes excubitorum , commander of the palace guard. [12] [13] During this period he married Lupicina; no surviving children are recorded from this marriage. According to contemporary historian Procopius, Lupicina was a barbarian slave who had been Justin's concubine before their marriage. [14]


During the night of 8–9 July 518, Anastasius died and his silentarii , a senior servant, summoned Justin and Celer to his deathbed. Celer was the magister officiorum (master of offices) and commander of the palace regiments of the Scholae Palatinae , a force of parade-ground display troops. By morning the event had been announced throughout the capital, Constantinople. The high officials, including John of Cappadocia, the recently appointed Patriarch of Constantinople, were summoned to the Great Palace for the election of a new emperor. Meanwhile, the people gathered in the Hippodrome of Constantinople and awaited the proclamation of the name of the new emperor. [15]

Anastasius had died childless but had a host of known relatives. [16] This extensive family included several viable candidates for the throne. [15] His brother Flavius Paulus had served as consul in 496. [17] According to John Malalas, the praepositus sacri cubiculi (grand chamberlain), Amantius, had intended to have Theocritus, commander of an elite guard unit, elected to the throne. [18] Theocritus and Amantius were relying on their control of a large military force and on buying the support of the other officials. Amantius was said to have given a substantial sum of money to Justin in order to buy his support. However, Justin controlled a smaller, but higher-quality group of soldiers, and used the money to buy support for himself. He was elected as the new emperor by the council and was proclaimed emperor in the Hippodrome as Justin I. [15]

His wife became his empress consort under the name Euphemia. The name was probably chosen for reasons of respectability. [14] The original Euphemia was a Christian martyr during the Diocletianic Persecution. She was a local saint of Chalcedon and the Council of Chalcedon (451) had taken place in a cathedral consecrated in her name. [19] The selection of this name was an early indication that Justin and Lupicina were fervent Chalcedonian Christians. [14] The population of the capital was supportive because of his strong Chalcedonian position on the fierce Christological debate of the time, in opposition to his predecessor's Monophysite leanings.[ citation needed ]


Justin cemented his position by assassinating potential opponents, especially anti-Chalcedonian supporters of Anastasius. Both Amantius and Theocritus were executed nine days after the election. [15] A career soldier with little knowledge of statecraft, Justin surrounded himself with trusted advisors. The most prominent of these was his nephew Flavius Petrus Sabbatius, whom he adopted as his son and invested with the name Iustinianus (Justinian). [20]

Justin endeavoured to cultivate client states on the borders of the Empire, and avoided any significant warfare until late in his reign. [21]

In 497 Anastasius had agreed with Theoderic, the Ostrogothic king of Italy, that he would rule Italy as Anastasius' deputy. This preserved Italy as nominally a part of the Empire, and neutralised a potentially dangerous neighbour. The arrangement suited Theodoric, as the Ostrogoths were a small aristocratic minority in Italy and the blessing of Constantinople helped reconcile the majority of the population to their rule. The feelings of the majority of Italians towards the Empire were mixed, as Anastasius was a Monophysite, while they were Chalcedonian. The Ostrogoths were Arians, and there was a tendency to consider both them and Monophysites as different breeds of heretics. With a strongly Chalcedonian emperor on the throne and the Italian-based papacy formally healing the rift the situation became less stable. Initially relations were friendly. Theodoric's son-in-law Eutharic was appointed consul in Constantinople in 519 and confirmed as Theodoric's heir. Eutharic died in 522, by which time Justin's policies, possibly influenced by Justinian, had become more anti-Arian. In 526 Theodoric died, leaving Eutharic's ten-year-old son Athalaric as heir to the throne. [22] [23]

A number of initiatives in respect of neighbouring states were founded on religious motives, and were usually developed by Justinian as he assumed more power towards the end of Justin's reign. Kaleb I of Aksum was probably encouraged to aggressively enlarge his empire by Justin. Contemporary chronicler John Malalas reported that Byzantine merchants were robbed and killed by the Jewish King of the south Arabian Kingdom of Himyar, causing Kaleb to claim, "You have acted badly because you have killed merchants of the Christian Romans, which is a loss both to myself and my kingdom." [24] Himyar was a client state of the Sassanian Persians, perennial enemies of the Byzantines. Kaleb invaded Himyar, vowing to convert to Christianity if successful, which he was in 523. Justin thus saw what is now Yemen pass from Sassanian control to that of an allied and Christian state. [24]

A number of small states on the borders of the Byzantine Empire and of Sassanian Persia were constant areas of contention between the two powers. The Georgian Principality of Iberia was in the Sassanian sphere of influence, but was Christian. Iberian bishops were sent to Antioch in the Byzantine Empire to be consecrated. Vakhtang I of Iberia was encouraged into war with the Sassanians. A "fervent Christian", his religious policies were "part and parcel of his larger strategic aims". [24] After a lengthy struggle he was defeated and Iberia subjugated as a Sassanian province in 522. [24]

Lazica was another border state; it was Christian, but in the Sassanid sphere. Its king, Tzath, wished to reduce Sassanid influence. In 521 or 522, he went to Constantinople to receive the insignia and royal robes of kingship from Justin's hand and to make his submission. He was also baptized as a Christian and married a Byzantine noblewoman, Valeriana. After having been confirmed in his kingdom by the Byzantine emperor, he returned to Lazica. Shortly after Justin's death the Sassanids attempted to forcibly regain control, but were beaten off with assistance from Justin's successor. [25] [26]

In 524 the Sassanid emperor Kavadh I approached Justin asking that he formally adopt his youngest son, Khosrow, in order to secure his succession over his elder, but less favoured, brothers. Justin was agreeable, but, aware that being childless himself an adopted Persian son would have a claim on the Byzantine throne, offered adoption according to barbarian custom. The Persians were insulted and broke off all negotiations. [27] In 526, the Byzantines raided Persian Armenia at Justinian's initiative. Justinian was increasingly taking control of policy from his aging uncle. The raiding parties were led by two of Justinian's up-and-coming military protégees, Sittas and Belisarius. The raids achieved little, other than to make a statement of intent. [23]


Justin's reign is noteworthy for the resolution of the Acacian schism between the eastern and western branches of the Christian church. On ascending the throne Justin invited Pope Hormisdas to Constantinople for negotiations. Justinian sent a similar, but separate, invitation; said to have been closer to a summons. Hormisdas promptly despatched a delegation to Constantinople with instructions to state the orthodox position rather than to negotiate. Carrying out a policy developed by his nephew Justinian, the future emperor, Justin endorsed Rome's view on the question of the dual nature of Christ. On 28 March 519, in the cathedral of Constantinople in the presence of a great throng of people, a reluctant Patriarch John II accepted the formula of Pope Hormisdas and the end of the schism was concluded in a solemn ceremony. [23]

For the first three years of his reign Justin persecuted the Monophysites, even serving soldiers. Thereafter he adopted a more pragmatic approach. In 523 Justin issued a strict edict against Arianism. Theodoric, King of the Ostrogoths and ruler of Italy, was an Arian himself, as were most Ostrogoths. He despatched Pope John I, Pope Hormisdas' successor, to Constantinople with firm instructions to obtain a policy reversal. John received an exceptionally warm welcome; the population of Constantinople applauded him, Justin laid on celebrations, prostrated himself at the Pope's feet and insisted on being re-crowned by the Pope's hands. John did not succeed in having the edict overturned, it seems that he did not press the matter. On his return to Italy an enraged Theodoric had him flung into prison, where he shortly died. [23] [28] [29]

Again encouraged by Justinian, Justin increasingly expressed his position as emperor as a religious one. He claimed that "we have been elected to the empire by favour of the indivisible Trinity. [30] [31] Edicts were endorsed with "We continuously commit ourselves to all plans and actions in the name of Jesus Christ". [32] In either 519 or 522 Justin abandoned the tradition of depicting pagan symbols on the reverse of his coins and seals. "During the reign, the characteristic identifying the reverse female figure as Victory, a high girdle below the breasts, was substituted by a tunic, therefore identifying the figure as an angel." [21] This was a very public and widespread restatement of the Empire as a Christian state. [21]

Later years

The later years of the reign of Justin were marked by increased tension with the Empire's neighbours, especially the Ostrogoths, and the Sassanids. In 526 Antioch was destroyed by an earthquake with an estimated 250,000 deaths. Justin arranged for sufficient money to be sent to the city for both immediate relief and to start reconstruction. The rebuilding of the Great Church and many other buildings was overseen by Ephraim, the comes Orientis , whose efforts saw him replace Euphrasius as the Chalcedonian Patriarch of Antioch. Many of the buildings erected after the earthquake were destroyed by another major earthquake in November 528, although there were far fewer casualties. [33] [34] [35]

Procopius of Caesarea's Byzantine historia indicate that Justin I's mental faculties had begun to decline in his old age, going as far as to write "the Emperor, as an idiot and advanced in age, caused the laugh of the environment, and was also accused of delays in decisions and inability for his duties." [36]


During his uncle's reign Justinian successively occupied the positions of comes domesticorum , commander of the imperial guard, patrician, and, in 521, consul. In 525, Justin repealed a law that effectively prohibited a member of the senatorial class from marrying women from a lower class of society, including the theatre, which was considered scandalous at the time. This edict paved the way for Justinian to marry Theodora, a former mime actress, and eventually resulted in a major change to the old class distinctions at the Imperial court. She came to participate in Justinian's rule with very significant and powerful influence. Justin's health began to decline and he formally named Justinian as co-emperor and, on 1 April 527, as his successor. On 1 August Justin died and was succeeded by Justinian. [37]


The Cilician city of Caesarea was renamed Justinopolis in 525, in honour of Justin I. The name persisted until the 12th century when Thoros I, king of Armenian Cilicia, made it his capital and renamed it Anazarbus. [38]

518 Calendar year

Year 518 (DXVIII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Paulus without colleague. The denomination 518 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Zeno (emperor) Eastern Roman emperor from 474 to 475 and from 476 to 491

Flavius Zeno was Eastern Roman emperor from 474 to 475 and again from 476 to 491. Domestic revolts and religious dissension plagued his reign, which nevertheless succeeded to some extent in foreign issues. His reign saw the end of the Western Roman Empire following the deposition of Romulus Augustus and the death of Julius Nepos, but he was credited with contributing much to stabilising the Eastern Empire.

Germanus was an East Roman (Byzantine) general, one of the leading commanders of Emperor Justinian I. Germanus was Emperor Justinian's cousin, and a member of the ruling dynasty. He held commands in Thrace, North Africa, and the East against Persia, and was slated to command the final Byzantine expedition against the Ostrogoths. Having married into the Gothic Amal royal line through his second wife Matasuntha and a distinguished service record, at the time of his sudden death, he was considered the probable heir to Emperor Justinian.

Leonid dynasty

The Leonid dynasty produced five Roman emperors during Late Antiquity, reigning over the Roman Empire from 457 to 518. The dynasty's patriarch was Leo I, who was made Roman emperor in 457. Leo's daughter Ariadne became empress and mother to an emperor, and her two husbands were themselves each made emperor in turn. Another relative whose name does not survive of Leo I or his wife Verina married the future augustus Julius Nepos, the last emperor in the western Roman Empire. The dynasty of Leo succeeded the preceding Valentinianic dynasty and Theodosian dynasty whose family trees were conjoined and ruled concurrently. Besides Julius Nepos, who administered no more than a rump state the Roman province of Dalmatia in the western empire during the fall of the west, the dynasty's emperors governed the eastern empire.

Gothic War (535–554) A war between the Byzantine Empire and the Ostrogothic Kingdom of Italy

The Gothic War between the East Roman (Byzantine) Empire during the reign of Emperor Justinian I and the Ostrogothic Kingdom of Italy took place from 535 until 554 in the Italian peninsula, Dalmatia, Sardinia, Sicily and Corsica. It was one of the last of the many Gothic Wars with the Roman Empire. The war had its roots in the ambition of the East Roman Emperor Justinian I to recover the provinces of the former Western Roman Empire, which the Romans had lost to invading barbarian tribes in the previous century.

Ostrogothic Kingdom

The Ostrogothic Kingdom, officially the Kingdom of Italy, was established by the Germanic Ostrogoths in Italy and neighboring areas from 493 to 553.

Theodora (wife of Justinian I) Augusta

Theodora was an Eastern Roman empress by marriage to emperor Justinian. She became empress upon Justinian's accession in 527 and was one of his chief advisers, albeit from humble origins. Along with her spouse, Theodora is a saint in the Eastern Orthodox Church and in the Oriental Orthodox Church, commemorated on 14 November and 28 June respectively.

Sophia (empress) Augusta

Aelia Sophia was the Empress consort of Justin II of the Byzantine Empire, and regent during the incapacity of her spouse from 573 until 578. She was interested in economic and financial matters during Justin's reign.

Euphemia (empress) Augusta

Euphemia, whose original name was Lupicina, was an Empress of the Byzantine Empire by marriage to Justin I.

Byzantine Empire under the Justinian dynasty

The Byzantine Empire had its first golden age under the Justinian Dynasty, which began in 518 AD with the Accession of Justin I. Under the Justinian Dynasty, particularly the reign of Justinian I, the Empire reached its largest territorial point, 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 ascension of his successor, Phocas.

Vitalian was a general of the East Roman (Byzantine) Empire. A native of Moesia in the northern Balkans, and probably of mixed Roman and Gothic or Scythian barbarian descent, he followed his father into the imperial army, and by 513 had become a senior commander in Thrace.

Ostrogothic Papacy

The Ostrogothic Papacy was a period from 493 to 537 where the papacy was strongly influenced by the Ostrogothic Kingdom, if the pope was not outright appointed by the Ostrogothic King. The selection and administration of popes during this period was strongly influenced by Theodoric the Great and his successors Athalaric and Theodahad. This period terminated with Justinian I's (re)conquest of Rome during the Gothic War (535–554), inaugurating the Byzantine Papacy (537-752).

Pompeius was a politician of the Eastern Roman Empire and relative of the Emperor Anastasius I.

Theocritus was a candidate to the throne of the Byzantine Empire in 518. He lost to Justin I.

Byzantine Anatolia

The history of the Eastern Roman Empire (324–1453) is generally considered to fall into three distinct eras:

Amantius was the head chamberlain of the Byzantine emperor Anastasius I. Defeated by Justin I in the intrigues and power struggles after Anastasius' death, he was executed.
