Rome, according to tradition, was founded in 753 BCE. It wasn't until 509 BCE, however, that the Roman Republic was founded. The Republic functioned effectively until civil war during the first century BCE led to the fall of the Republic and the creation of the Roman Empire in 27 CE.While the Roman Republic was a time of great advances in science, art, and architecture, the "fall of Rome" refers to the end of the Roman Empire in 476 CE.

Fall of Rome Events Short Timeline

The date at which you start or end a Fall of Rome timeline is subject to debate and interpretation. One could, for example, start the decline with the reign of Marcus Aurelius' successor, his son, Commodus. This period of imperial crisis is a compelling choice and easy to understand as a starting point.

This Fall of Rome timeline, however, uses standard events and marks the end with Gibbon's conventionally accepted date for the fall of Rome in A.D. 476 (from his famous histories entitled The Rise and Fall of the Roman Empire). So this timeline begins just before the east-west splitting of the Roman Empire, a time described as chaotic, and ends when the last Roman emperor was deposed but allowed to live out his life in retirement.
