Herod Archelaus was a son of Herod the Great and the brother of Herod Antipas. He inherited Judea and Samaria after his father’s death.
Archelaus is mentioned in Matthew 2:22. Joseph and Mary avoided returning to Judea because Archelaus ruled there, and they went instead to Galilee.
The supplied material identifies Archelaus chiefly by his relationship to Antipas and his place in the Herodian succession. No further historical details are given here.
