The term is used in two different senses.
1) Originally a Greek term meaning "ruler of a quarter," the title "tetrarch" was given by Augustus Caesar to three of Herod the Great's successors. Dividing Herod's territory into four parts, Galilee was ruled by his son Herod Antipas "the tetrarch," Iturea and Traconitis by another son Herod Philip "the tetrarch," and Abilene by Lysanias "the tetrarch." The fourth part, Judea, was ruled by yet another son, Archelaus, as "ethnarch," ('ruler of the people').
2) During his reign as Roman emperor, Diocletian (r. 284-305) reformed the administration of the empire by appointing his son-inlaw, Maximian, first as deputy emperor (Caesar) and later as Augustus, on the condition that major decisions would always be made in consultation with the elder Caesar. As the deteriorating conditions made administration even more demanding, Maximian appointed in 293 a deputy emperor of his own. He was followed by Diocletian a short while afterwards. This system of administration became known as the 'tetrarchy,' on the understanding that the two deputy emperors would one day succeed the reigning augusti. One of these deputies was a man named Constantius, whose son would make Christianity the official religion of the Roman Empire. Though intended to put an end to the endless cycles of dynastic building by the emperors before him, it unreveled soon after his retirement in 305. This concept of the tetrarchy, though having nothing to do with preaching the Bible, per se, is a fact of history important for understanding Church history.
