governor of a fourth part. Dictionaries-Smith's Bible Dictionary-Tetrarch, properly the sovereign or governor of the fourth part of a country. (Matthew 14:1; Luke 3:1; 9:7; Acts 13:1) The title was, however, often applied to any one who governed a Roman province, of whatever size. The title of king was sometimes assigned to a tetrarch.
Although the term tetrarch was current in antiquity, it was never used of the imperial college under Diocletian. Instead, the term was used to describe independent portions of a kingdom that were ruled under separate leaders. The tetrarchy of Judaea, established after the death of Herod the Great, is the most famous example of the antique tetrarchy.
