The Persian Empire is famously known for its elaborate bureaucracy and control over vast territories that spanned three continents: Asia, Africa, and Europe. Established by Cyrus the Great in the 6th century BCE, it became one of the largest empires in history, renowned for its sophisticated administrative systems. The empire was divided into satrapies, each governed by a satrap who reported directly to the emperor. This structure enabled efficient governance and communication across diverse regions. The Persian Empire also promoted trade and cultural exchange, contributing significantly to the development of art, infrastructure, and the spread of Zoroastrianism, influencing subsequent civilizations.
