How Did Rome Split Into East and West?

By Alice Nichols

The split of the Roman Empire into East and West was a significant event in history that had long-lasting effects on the development of Europe. This division occurred in the late 4th century, resulting in two distinct political and cultural entities. Let’s explore how this split came about and what its consequences were.

The Rise of Constantine

In order to understand the split of Rome, we must first examine the rise of Constantine the Great. He was a prominent Roman emperor who ruled from AD 306 to 337. Constantine is known for his conversion to Christianity and his efforts to reunify the empire.

Constantine’s Conversion: Constantine’s conversion to Christianity played a significant role in shaping the future of Rome. Under his rule, Christianity gained prominence, eventually becoming the dominant religion in both halves of the empire.

The Administrative Reforms

Constantine introduced several administrative reforms that laid the foundation for a divided empire:

  • The Foundation of Constantinople: In AD 330, Constantine established a new capital called Constantinople (modern-day Istanbul) in the Eastern part of the empire. This move helped shift power away from Rome towards the East.
  • The Division of Power: To ensure efficient governance, Constantine divided administrative responsibilities between two separate capitals – Rome in the West and Constantinople in the East.
  • The Edict of Milan: In AD 313, Constantine issued this edict, granting religious freedom to Christians within the empire. This marked an important turning point for Christianity and further solidified its influence.

The Crisis and Split

Despite Constantine’s efforts towards unity, the empire faced numerous challenges that ultimately led to its split:

  • Barbarian Invasions: The Roman Empire encountered increasing pressure from barbarian invasions, particularly in the West. The Visigoths sacked Rome in AD 410, further weakening the Western half.
  • Theodosius I: After Constantine’s death, his sons divided the empire between themselves.

    However, it was Theodosius I who made the division official in AD 395, upon his death. He appointed his sons Arcadius as the Eastern Emperor and Honorius as the Western Emperor.

  • Economic and Social Factors: Economic decline and social unrest also contributed to the division. The West faced financial difficulties, while the East remained relatively prosperous.

The Consequences

The split of Rome into East and West had far-reaching consequences:

  • Cultural Divide: Over time, distinct cultural differences emerged between Eastern (Byzantine) and Western Europe. The Eastern half embraced Greek language and culture, while Latin continued to dominate in the West.
  • Political Instability: With two separate empires came political instability.

    Various emperors rose and fell on both sides, leading to frequent conflicts and power struggles.

  • The Fall of Rome: The Western Roman Empire eventually succumbed to external pressures and internal decay. In AD 476, Rome was conquered by Germanic tribes, marking the end of ancient Rome.

The Legacy

The split of Rome into East and West left a lasting legacy on European history. The Eastern Roman Empire (Byzantine Empire) continued to thrive for centuries, preserving Greek and Roman traditions. Meanwhile, the Western Roman Empire’s fall paved the way for the Middle Ages and the rise of new powers in Europe.

In conclusion, the split of Rome into East and West was a complex process influenced by political, social, and economic factors. Although Constantine aimed for unity, circumstances ultimately led to a division that shaped European history for centuries to come.
