Tetrarch

Easton's Bible Dictionary

Strictly the ruler over the fourth part of a province; but the word denotes a ruler of a province generally (Matthew 14:1; Luke 3:1,19; 9:7; Acts 13:1 ). Herod and Phasael, the sons of Antipater, were the first tetrarchs in Palestine. Herod the tetrarch had the title of king (Matthew 14:9 ).
