135 CE: The Bar Kokhba Revolt and Its Aftermath
- Event: Simon bar Kokhba’s rebellion in Judea was crushed by the Roman Emperor Hadrian. The land was devastated, and the province was renamed Syria Palaestina.
- Impact: This ended major Jewish political resistance to Roman rule and marked the beginning of a Jewish diaspora away from Judea【8】【9】【10】.
284 CE: Diocletian’s Tetrarchy
- Event: Emperor Diocletian implemented the Tetrarchy, dividing the empire into four regions governed by co-emperors.
- Significance: This set the stage for the later permanent division into Eastern and Western Empires【9】【10】.
313 CE: Edict of Milan
- Event: Legalization of Christianity by Constantine and Licinius.
- Significance: This began the transformation of the Roman Empire into a Christian state【9】【10】.
330 CE: Founding of Constantinople
- Event: Constantine I officially dedicated Byzantium as his new capital, renaming it Constantinople.
- Context: This move reflected the economic and strategic importance of the Eastern provinces, where the city could defend against threats from Persia and facilitate trade【9】【10】.
364 CE: Permanent Division of the Empire
- Event: Emperor Valentinian I divided the empire between himself (West) and his brother Valens (East).
- Reasons:
- Administrative challenges of governing such a vast territory.
- Increasing external threats required focused military leadership in both regions.
- Economic disparity favored the East, where Constantinople became a center of wealth and stability【8】【9】【10】.
395 CE: Official Division of the Roman Empire
- Event: Upon the death of Emperor Theodosius I, the empire was formally split between his two sons—Arcadius in the East and Honorius in the West.
- Significance: This division is seen as the origin of the Byzantine Empire in the East and the beginning of the West’s decline【9】.
476 CE: Fall of the Western Roman Empire
- Event: The Western Roman Empire fell when child emperor Romulus Augustulus was deposed by Odoacer.
- Odoacer was a barbarian soldier and statesman from the Middle Danube who deposed the Western Roman child emperor Romulus Augustulus and became the ruler of Italy (476–493). Odoacer’s overthrow of Romulus Augustulus is traditionally understood as marking the end of the Western Roman Empire.[d] Although he held power over Italy, he also represented himself as the client of the Eastern Roman Emperor in Constantinople, Zeno. He was referred to not only as a king (Latin: rex), but also as duke (Latin: dux), or using the Roman honorific patrician, granted by Zeno. Odoacer himself used the title of king in the only surviving official document that emanated from his chancery, and it was also used by the consul Basilius.[1][e] He had the support of the Roman Senate and was able to distribute land to his followers without much opposition. Unrest among his warriors led to violence in 477–478, but no such disturbances occurred during the later period of his reign. Although Odoacer was an Arian Christian, he rarely intervened in the affairs of the Trinitarian state church of the Roman Empire. This bullet is from Wikipedia.
- Significance: The Byzantine Empire, centered in Constantinople, continued as the direct successor of Roman governance and culture in the East【8】【9】.

- Architecture: Commissioned the Hagia Sophia, a masterpiece of Byzantine architecture【9】【10】.
610 CE: Rise of Heraclius
- Event: Heraclius became emperor, transforming the Byzantine Empire into a Greek-speaking state.
- Significance: He restructured the military and administrative systems and successfully defended against Persian and early Arab invasions【9】.
717–718 CE: Siege of Constantinople
- Event: The Byzantine Empire, under Emperor Leo III, successfully defended Constantinople from a massive Umayyad Arab siege using Greek fire.
- Impact: This victory preserved the empire as a bastion of Christianity in the East【9】【10】.
Broader Context
While the Western Roman Empire collapsed under pressure from Germanic invasions and internal decline, the Eastern Roman Empire (Byzantium) thrived. Constantinople’s strategic location, strong economy, and cohesive governance enabled it to act as a bridge between the classical Roman world and medieval Europe. The Byzantine Empire preserved Roman law, Christian theology, and classical knowledge, shaping the future of Europe and the Near East【9】【10】.

330 CE to 1453 CE: The Byzantine Empire
By Cartwright, M. (2018, September 19). Byzantine Empire. World History Encyclopedia. Retrieved from https://www.worldhistory.org/Byzantine_Empire/. The following bullets are extracts.

By Simeon Netchev here
- The Byzantine Empire existed from 330 to 1453. It is often called the Eastern Roman Empire or simply Byzantium. The Byzantine capital was founded at Constantinople by Constantine I (r. 306-337). The Byzantine Empire varied in size over the centuries, at one time or another, possessing territories located in Italy, Greece, the Balkans, Levant, Asia Minor, and North Africa.
- Byzantium was a Christian state with Greek as the official language. The Byzantines developed their own political systems, religious practices, art, and architecture. These were all significantly influenced by the Greco-Roman cultural tradition but were also distinct and not merely a continuation of ancient Rome. The Byzantine Empire was the longest-lasting medieval power…
- The differences in the eastern and western church was one of the reasons that the Byzantine Empire received such a poor representation in western medieval histories. Frequently Byzantines were portrayed as decadent and shifty, their culture stagnant, and their religion a dangerous heresy. The churches of the east and west disagreed on who should have priority, the Pope or the Patriarch of Constantinople. Matters of doctrine were also contested, such as did Jesus Christ have one human and one divine nature combined or just a divine nature. Clerical celibacy, the use of leavened or unleavened bread, the language of service, and the use of imagery were all points of differences, which, with the fuel of political and territorial ambitions added into the volatile mix of emotions, led to the Church Schism of 1054.
- The role of Byzantine women, as with the men, depended on their social rank. Aristocratic women were expected to manage the home and care for the children. Although able to own property, they could not hold public office and spent their free time weaving, shopping, going to church or reading (although they had no formal education). Widows became the guardian of their children and could inherit equally with their brothers. Many women worked, as men, in agriculture and various manufacturing industries and food services. Women could own their own land and businesses, and some would have improved their social position through marriage. The least respected professions were, as elsewhere, prostitutes and actresses.
- Most historians agree that the Byzantine Empire terminated on Tuesday 29 May 1453, when the Ottoman Sultan Mehmed II (r.1444-6 & 1451-81) conquered Constantinople.
