Who was the founder of the Achaemenid Empire?

• A. Darius I
• B. Xerxes I
• C. Cyrus the Great
• D. Cambyses II

Answer: (C)

Cyrus the Great is the founder of the Achaemenid Empire because he united the Persian tribes and overthrew the Median Empire, establishing the first large Persian state around 550 BCE. From there he expanded to conquer Lydia and Babylon, creating a vast, centralized realm under a single ruler. This set the dynastic line and administrative approach that defined the empire for generations. Later rulers like Cambyses II, Darius I, and Xerxes I expanded and reorganized the empire, but they did not found it; they built on Cyrus’s foundation. Cyrus also introduced governance practices that helped manage a diverse empire, such as allowing local customs and laws to continue where possible, which helped maintain stability across a wide range of peoples.
