داریوش (Darius) was a prominent king of the Achaemenid Empire, ruling from 522 to 486 BCE. He is known for his administrative genius, expanding the empire to its greatest extent and implementing a system of satrapies, or provinces, to manage its vast territories. Darius also initiated the construction of the famous Persepolis, which served as the ceremonial capital of the empire. In addition to his architectural achievements, داریوش is recognized for his efforts in standardizing weights, measures, and currency, which facilitated trade across the empire. He is also known for the Behistun Inscription, a multilingual inscription that commemorates his victories and provides insight into the history of the Achaemenid Empire.
