It is difficult to provide a comprehensive list of all events in Ancient Rome in a single response, as the history of Rome spanned over a thousand years. However, I can provide an overview of some key events and the approximate order in which they occurred:
1. Founding of Rome (traditionally dated to 753 BCE)
2. Roman Republic (509 BCE - 27 BCE):
- Expulsion of the last Etruscan king Tarquin the Proud (509 BCE)
- Establishment of the Roman Republic and adoption of a republican system of government
- Expansion of Roman territory through conquest and colonization
- Punic Wars: series of conflicts with Carthage, with Rome emerging victorious and gaining control over the western Mediterranean (264 BCE - 146 BCE)
- Rise and fall of influential figures like Julius Caesar, Pompey, and Cicero
- Internal conflicts and political instability (e.g., Gracchi brothers' reforms and subsequent violence)
3. Roman Empire (27 BCE - 476 CE):
- Transition from Republic to Empire (27 BCE)
- Augustus becomes the first Roman Emperor (27 BCE)
- Pax Romana (Roman Peace): a period of relative stability and territorial expansion (27 BCE - 180 CE)
- Construction of major infrastructure projects (e.g., aqueducts, roads, Colosseum)
- Spread of Christianity, initially as a persecuted religious movement
- Emperor Constantine legalizing Christianity (313 CE)
- Division of the Roman Empire into East and West (395 CE)
- Fall of the Western Roman Empire (476 CE)
Within this broad timeline, numerous other events took place, such as the reigns of various emperors, wars and conquests, building projects, cultural developments, and social changes. It is recommended to consult detailed historical sources for a more comprehensive understanding of Ancient Roman history.
