What were the satrapies and satraps?

Satrapies were administrative regions in the Persian Empire, each governed by a satrap, who acted as a provincial governor. The satraps were responsible for maintaining order, collecting taxes, and ensuring loyalty to the central Persian authority. This system allowed for efficient governance over the vast empire, enabling the Persian kings to maintain control over diverse cultures and territories. The satraps often had considerable autonomy but were expected to report to the emperor and enforce his policies.
