How old is the Greek Empire?

The Greek Empire, often referred to in the context of ancient Greece, emerged around the 8th century BCE with the rise of city-states like Athens and Sparta. It reached its peak during the 5th century BCE, particularly with the Athenian Golden Age. The influence of Greek culture continued well into the Hellenistic period, which began after the conquests of Alexander the great in the 4th century BCE. Thus, the roots of the Greek Empire date back over 2,700 years.
