Timeline of Ancient Rome Explained

Unlike other classical civilization timelines, most events in Roman history are perfectly dated. This is partly due to the passion the Romans had for writing things down, but also because their historians made sure to document every single fact about Roman history. From its inception in the times of Romulus and Remus, to the demise of the Western Roman Empire in the 5th century CE, there is a clear account of everything.

For completeness purposes, we will include in our timeline some of the history of the so-called Eastern Roman Empire, but it should be stated that the Byzantine Empire is a far cry from the classical Roman tradition that started with Romulus betraying his brother Remus.

Let’s take a look at the ancient Roman timeline.

Roman Kingdom (753-509 BCE)

Romulus Remus

According to the myth described in the Aeneid, the early Romans settled in the Latium region. Two brothers, Romulus and Remus, direct descendants of the Greek hero Aeneas, were supposed to build a city in the region.

There were two problems in this sense:

First, that the area next to the Tiber River was already populated by the Latin, and second, that the two brothers were also rivals. Following the failure to follow ritual rules by Remus, he was killed by his brother Romulus, who went on to found Rome in an area known as the Seven Hills.

The Republic is probably the most studied and known period in Roman history, and for a good reason.

The Last Event of the Ancient Roman Civilization

The Romans grew from a single lineage –that of Aeneas – into the most powerful empire in the West, only to topple down after a series of so-called invasions by so-called barbaric peoples.

In the meantime, it was home to kings, rulers elected by the people, emperors, and dictators. While its heritage continued in the Eastern Roman Empire, the Byzantines can hardly be considered Romans, as they speak another language, and are Catholic.

This is why the fall of Rome in the hands of Odoacer can be considered the last event of the ancient Roman civilization.
