The Romans created the largest empire in antiquity, starting with the founding of Rome in 753 BC and ending with the fall of the Western Roman Empire in 476 AD. Over this 1200 year period, Rome transitioned from a monarchy to a republic and then an empire that dominated territories across Europe, North Africa and the Middle East. Key events included the establishment of the Roman Republic in 509 BC, the Punic Wars with Carthage, the expansion across the Mediterranean under the empire, and the division of the empire into Western and Eastern halves in 395 AD prior to the fall of the Western Empire.
