Moreover, Justin II was moving away from the foreign policy of Justinian, and believed in dealing more strictly with bordering states and peoples.

Again, Justinian moved toward compromise in the religious edict of 15 March 533, and congratulated himself that Pope John II admitted the orthodoxy of the imperial confession.

Some, including the Byzantine chronicler Theophanes, have claimed that Konon's family had been resettled in Thrace, where he entered the service of Emperor Justinian II, when the latter was advancing on Constantinople with an army of 15, 000 horsemen provided by Tervel of Bulgaria in 705.

In the late 7th century Justinian II organized a massive expeditions against the Sklaviniai of the Greek peninsula, in which he reportedly captured over 110, 000 Slavs and transferred them to Cappadocia.

The actual negotiations on the contentious articles were handled by Gregory, with the result that the emperor Justinian II agreed that the Papacy could disregard whichever of the council ’ s decisions it wished to.

As a result of the dispute, the Byzantine Emperor Justinian II ordered Sergius I's abduction ( as his predecessor Constans II had done with Pope Martin I ), but with the assistance of the exarch of Ravenna, Sergius I was able to avoid trial in Constantinople.

Enraged, Emperor Justinian II dispatched his magistrianus, also named Sergius, to Rome to arrest bishop John of Portus, the chief papal legate to the Third Council of Constantinople and Boniface, the papal counselor.

Eventually, Justinian II ordered Sergius I's arrest and abduction to Constantinople by his notoriously violent bodyguard protospatharios Zacharias.

The Code and the Institutes of Justinian were known in Western Europe, and along with the earlier code of Theodosius II, served as models for a few of the Germanic law codes ; however, the Digest portion was largely ignored for several centuries until around 1070, when a manuscript of the Digest was rediscovered in Italy.

Erected on the site of pagan temples and three previous St. Sophias, the first of which was begun by Constantine, this fourth church was started by Justinian in 532 and completed twenty years later.

Actually an underground cistern, its roof supported by rows and rows of pillars, it was built by Justinian in the Sixth Century to supply the palace with water.

In particular the so-called Plague of Justinian had ravaged the region and conflict remained endemic, with the Three-Chapter Controversy sparking religious opposition and administration at a standstill after the able governor of the peninsula, Narses, was recalled.

Anthemius of Tralles ( c. 474 – before 558 ; ) was a Greek professor of Geometry in Constantinople ( present-day Istanbul in Turkey ) and architect, who collaborated with Isidore of Miletus to build the church of Hagia Sophia by the order of Justinian I. Anthemius came from an educated family, one of five sons of Stephanus of Tralles, a physician.

The regnal year of the emperor was also used to identify years, especially in the Byzantine Empire after 537 when Justinian required its use.

The city was sacked by the Samaritans in 529, but rebuilt by the Byzantine emperor Justinian I. Bethlehem was conquered by the Arab Caliphate of ' Umar ibn al-Khattāb in 637, who guaranteed safety for the city's religious shrines.

During the Samaritan revolt of 529, Bethlehem was sacked and its walls and the Church of the Nativity destroyed, but they were rebuilt on the orders of the Emperor Justinian I.

One of the first and throughout its history one of the most significant treatises of the common law, Bracton ’ s De Legibus et Consuetudinibus Angliae ( On the Laws and Customs of England ), was heavily influenced by the division of the law in Justinian ’ s Institutes.

The region was then ruled by the Ostrogoths up to 535, when Justinian I added the territory to the Byzantine Empire.

The emperor Justinian I ( 527 – 565 ) was known for his successes in war, for his legal reforms and for his public works.

Justinian was also concerned with other aspects of the city's built environment, legislating against the abuse of laws prohibiting building within of the sea front, in order to protect the view.

However, the social fabric of Constantinople was also damaged by the onset of Plague of Justinian between 541 – 542 AD.

In its preparation, centuries of material was examined, scrutinized for authenticity by leading experts, and harmonized as much as possible with opposing canons and even other codes, from the Codex of Justinian to the Napoleonic Code.

In the 6th century, the Neoplatonist philosopher Simplicius, who was persecuted for his pagan beliefs during the reign of Justinian, wrote an extant commentary on the Enchiridion.

Isidore of Miletus was one of the two main Byzantine Greek architects ( Anthemius of Tralles was the other ) that Emperor Justinian I commissioned to design the church of Hagia Sophia in Constantinople from 532-537A. D.

Isidore of Miletus was a renowned scientist and mathematician before Emperor Justinian I hired him, “ Isidorus taught stereometry and physics at the universities, first of Alexandria then of Constantinople, and wrote a commentary on an older treatise on vaulting .” Emperor Justinian I appointed his architects to rebuild the Hagia Sophia following his victory over protesters within the capital city of his Roman Empire, Constantinople.

Isidore of Miletus and Anthemius of Tralles originally planned on a main hall of the Hagia Sophia that measured 230 feet by 250 feet, making it the largest church in Constantinople, but the original dome was nearly 20 feet lower than it was constructed, “ Justinian suppressed these riots and took the opportunity of marking his victory by erecting in 532-7 the new Hagia Sophia, one of the largest, most lavish, and most expensive buildings of all time .” Although Isidore of Miletus and Anthemius of Tralles were not formally educated in architecture, they were scientists that could organize the logistics of drawing thousands of laborers and unprecedented loads of rare raw materials from around the Roman Empire to create the Hagia Sophia for Emperor Justinian I.
