Medo-Persian Satraps
The first large scale use of satrapies, or provinces, originates from the conception of the first Persian Empire under Cyrus the Great, beginning at around 530 BCE. However, Provincial organization originated during the Median era from at least 648 BCE.
Up to the time of the conquest of Media by Cyrus the Great, emperors ruled the conquered lands, through client kings and governors. The chief difference was that in Persian culture the concept of kingship was indivisible from divinity: divine authority validated the divine right of kings. The twenty satraps established by Cyrus were never kings, but viceroys ruling in the king's name, although in political reality many grabbed any chance to carve themselves an independent power base. Darius the Great gave the satrapies a definitive organization, increased their number to twenty-three and fixed their annual tribute (Behistun inscription).
The satrap was in charge of the land that he owned as an administrator, and found himself surrounded by an all-but-royal court; he collected the taxes, controlled the local officials and the subject tribes and cities, and was the supreme judge of the province before whose "chair" (Nehemiah 3:7) every civil and criminal case could be brought. He was responsible for the safety of the roads (cf. Xenophon), and had to put down brigands and rebels.
He was assisted by a council of Persians, to which also provincials were admitted; and was controlled by a royal secretary and by emissaries of the king, especially the "eye of the king" who made an annual inspection and exercised permanent control.
There were further checks on the power of each satrap: besides his secretarial scribe, his chief financial official (Old Persian ganzabara) and the general in charge of the regular army of his province and of the fortresses were independent of him and reported directly to the shah, periodically, in person. But the satrap was allowed to have troops in his own service.
- The great satrapies (provinces) were often divided into smaller districts, the governors of which were also called satraps and (by Greco-Roman authors) also hyparchs (actually Hyparkhos in Greek, 'vice-regents'). The distribution of the great satrapies was changed repeatedly, and often two of them were given to the same man.
- As the provinces were the result of consecutive conquests (the homeland had a special status, exempt from provincial tribute), both primary and sub-satrapies were often defined by former states and/or ethno-religious identity. One of the keys to the Achaemenid success (as with most enduring great empires) was their open attitude to the culture and religion of the conquered people, so the Persian culture was the one most affected as the Great King endeavoured to melt elements from all his subjects into a new imperial style, especially at his capital Persepolis.
- Whenever central authority in the empire weakened, the satrap often enjoyed practical independence, especially as it became customary to appoint him also as general-in-chief of the army district, contrary to the original rule. "When his office became hereditary, the threat to the central authority could not be ignored" (Olmstead). Rebellions of satraps became frequent from the middle of the 5th century. Darius I struggled with widespread rebellions in the satrapies, and under Artaxerxes II occasionally the greater part of Asia Minor and Syria was in open rebellion (Revolt of the Satraps).
The last great rebellions were put down by Artaxerxes III.
