Rome began as a small agricultural community in central Italy founded in 753 BC. It eventually grew into a powerful Republic that dominated the Mediterranean world. The Republic collapsed in the 1st century BC, leading to the founding of the Roman Empire in 27 BC. At its height, the Empire stretched from Britain to Egypt and Portugal to Iraq. Rome's location placed it within a cultural sphere influenced by Greek and Etruscan civilizations. The Romans developed advanced architecture, infrastructure, and systems of government that still influence Western societies today.
