The Roman Empire

The Roman Empire was one of the largest and most influential empires in world history, spanning from 27 BCE to 476 CE in the West and until 1453 CE in the East (as the Byzantine Empire). At its height, the empire controlled approximately 5 million square kilometers and governed over 60 million people, roughly 20% of the world's population at the time.

Origins and Rise

The Roman Kingdom (753-509 BCE)

According to tradition, Rome was founded in 753 BCE by Romulus and Remus. The early kingdom was ruled by seven kings:

3. Tullus Hostilius (673-642 BCE)
4. Ancus Marcius (642-617 BCE)
5. Tarquinius Priscus (616-579 BCE)
6. Servius Tullius (578-535 BCE)
7. Tarquinius Superbus (535-509 BCE)
