Which was bigger the Greek empire or the Persian Empire?

The Persian Empire was larger than the Greek Empire at its height. The Persian Empire, particularly during the Achaemenid dynasty, spanned three continents—Asia, Africa, and Europe—encompassing a vast territory that included parts of modern-day Iran, Egypt, Turkey, and beyond. In contrast, the Greek Empire, primarily associated with city-states like Athens and Sparta, was more fragmented and did not achieve the same territorial expanse as Persia. Thus, in terms of land area and influence, the Persian Empire was significantly bigger.
