Persia's satraps ruled like kings, but a royal eye watched them yearly
A satrap governed a Persian province with his own court, his own troops and the final say in local lawsuits. To stop these viceroys becoming kings, the empire split off their treasurers and generals and sent an official called the eye of the king on annual inspections. It did not always work.
The title descends from an Old Persian word meaning protector of the province, and it travelled widely: Greek satrapes, Sanskrit kshatrapa, and a Hebrew form in the Book of Esther. In modern Persian its descendant has shifted to mean town keeper. Provincial government in the region goes back to the Medes, at least to 648 BCE, but it was the Achaemenid Empire under Cyrus the Great, from around 530 BCE, that used satrapies on a large scale. Cyrus set up 26; Darius the Great organised them firmly, raised the number to 36 and fixed each one's yearly tribute.
In Persian thought kingship was bound up with divinity, so satraps were never kings, only viceroys acting in the king's name. Each collected taxes, oversaw local officials, subject cities and tribes, kept the roads safe from bandits and heard civil and criminal cases. A council of Persians and provincials advised him. Crucially, his scribe, his chief finance officer and the commander of the provincial army and fortresses answered directly to the Great King. The Achaemenids also tolerated local cultures and religions, and provinces often followed old state or ethnic boundaries.
Those checks eroded. When central power weakened, satraps were increasingly made army commanders too, and some posts became hereditary. Revolts grew frequent from the mid-fifth century BCE; under Artaxerxes II much of Asia Minor and Syria was at times in open rebellion, and Artaxerxes III crushed the last great uprisings.
The system outlived its creators. Alexander the Great kept the title even for Greek and Macedonian governors, and his successors carried it on in smaller provinces, with the Seleucids treating satraps as generals. The Sasanians appointed governors called shahrabs in royal cities. In India, Saka rulers known as the Western Satraps held power from 35 to 405 CE. Today the word survives mainly as an insult for a corrupt local strongman.
