Herod's will divided his kingdom among his sons. Archelaus was to succeed him as king, Antipas to receive Galilee and Peraea, and Philip Trachonitis and neighbouring provinces east of the Lake of Galilee. With modifications, this was confirmed by Augustus.
Ethnarchy of Archelaus. Archelaus, with the title not of King but of Ethnarch, received Idumea, Judea and Samaria, with Caesarea, Joppa, and Jerusalem. Gaza (with Gadara and Hippos) was put under the Province of Syria. Dora remained under the province of Syria.
Tetrarchy of Herod Antipas. Antipas received Galilee and Perea.
Tetrarchy of Philip. Philip received Paneas, Gaulanitis, Trachonitis, Batanea and Auranitis, with a certain part of the domain of Zenodorus.
Toparchy of Salome. Salome, Herod's sister, received Jamnia, Ashdod, Phasaelis and the palace of Askalon.
