Thank you!!! :-)

You're welcome.

The permanent split of the Roman Empire occurred in the year 395 AD. To find the answer, we need to understand the historical context of the Roman Empire.

The Roman Empire was initially unified under Emperor Augustus in 27 BC, following the end of the Roman Republic. It expanded its territories over the centuries and reached its height during the reign of Emperor Trajan in the 2nd century AD. However, as time went on, the Roman Empire faced various challenges and internal conflicts.

In the 3rd century AD, the empire experienced a period of political and economic instability known as the Crisis of the Third Century. During this time, the empire faced invasions from various barbarian tribes, economic decline, and internal power struggles. As a result, the empire experienced a series of short-lived and often competing emperors.

To address these challenges, the empire was divided into two administrative regions known as the Western Roman Empire and the Eastern Roman Empire. This division, known as the Tetrarchy, was implemented by Emperor Diocletian in 286 AD. The idea behind this separation was to improve governance and administration by allowing two emperors to rule over each region.

However, despite this division, the Roman Empire remained nominally unified until the death of Emperor Theodosius I in 395 AD. Theodosius I was the last emperor to rule over both the Eastern and Western regions. After his death, the empire was permanently split into the Western Roman Empire, with its capital in Rome, and the Eastern Roman Empire, with its capital in Constantinople (modern-day Istanbul).

Therefore, the year 395 AD marked the permanent split of the Roman Empire.
