Which ancient civilization lasted about 1000 years?

• A. Ancient Rome
• B. Ancient Egypt
• C. Ancient Greece
• D. Indus Valley Civilization

Answer: (A)

This question is about how long ancient civilizations lasted, not just where they began. Ancient Rome fits the idea of enduring about a millennium, roughly from the start of the Roman Republic in 509 BCE to the fall of the Western Roman Empire in 476 CE—about 985 years, around a thousand years. Some people note that Roman political continuity continued in the East as the Byzantine Empire for many more centuries, but the traditional view of Rome’s central span in the West is about a thousand years.

By comparison, Ancient Egypt persisted for several thousand years, from around 3100 BCE to 30 BCE, well beyond a thousand. Ancient Greece covered a few centuries—from roughly 800 BCE to 146 BCE—so a bit under a thousand. The Indus Valley Civilization lasted for a few centuries to a couple thousand years depending on dating, generally not centered on a single thousand-year span in the way Rome’s western history is.
