Until his death in 4 BCE, Herod the Great's monarchy included territories that once made up the kingdoms of Judah and Israel. Although he ruled over a rich, strategically crucial land, his royal title did not derive from heredity. His family came from the people of Idumea, ancient antagonists of the Israelites.
Yet Herod did not rule as an outsider, but from a family committed to Judaism going back to his grandfather and father. They had served the priestly dynasty of the Maccabees that had subjected Idumea to their rule, including the Maccabean version of what loyalty to the Torah required. Herod's father, Antipater, rose not only to manage affairs on behalf of his priestly masters, but to become a pivotal military leader. He inaugurated a new alignment of power: an alliance with Rome negotiated with Pompey and Julius Caesar. In the crucible of civil war among Romans as the Triumvirate broke up, and of war between Rome and Parthia, Antipater managed to leave his sons with the prospect of a dynasty.
Herod inherited the twin pillars of loyalty to Judaism and loyalty to Rome that became the basis of Herodian rule. He elevated Antipater's opportunism to a political art. During Herod's time, Roman power took its imperial form, and Octavian was responsible for making Herod king of Judea.
