What is the Greek empire?

The Greek Empire is often associated with the period of ancient Greece, particularly during the classical era from the 5th to 4th centuries BCE, marked by the rise of powerful city-states like Athens and Sparta. It is renowned for its contributions to philosophy, art, and democracy. The empire expanded significantly under the conquests of Alexander the great in the 4th century BCE, spreading Greek culture throughout the Mediterranean and into parts of Asia. Although it did not exist as a cohesive political entity, its cultural influence laid the foundation for Western civilization.
