Tetrarch
From Wikipedia, the free encyclopedia
Tetrarch is a Greek term for the holder of Imperial office under a Tetrarchy (form of government with four con-collegial heads; especially the Roman Empire since Emperor Diocletian's 293AD reform).
It can also refer, more loosely, to
- A provincial governor in a country composed of several smaller parts.
- A subordinate or dependent prince, or petty sovereign. For example, the Tetrarchs of Roman Palestine, such as Herod Antipas, were tributary kings (Matt. 14:9).
- A Macedonian officer in charge of a unit associated with the number four (tetra), such as a quarter of a larger unit (such as a phalanx, or in one case a 'company' of 64 footmen), or comprising four smaller units (in one case 4 lochoi, each under a lochagos).
- A Roman military rank, similar to the previous Greek usage
- A British light tank of World War II, see Tetrarch tank
