History of ancient Israel and Judah
In 64 BCE the Roman general Pompey took over Jerusalem and made the Jewish kingdom a client of Rome. In 57-55 BCE Aulus Gabinius, proconsul of Syria, split it into Galilee, Samaria & Judea, with 5 district Sanhedrin/Synedrion (councils of law). In 40-39 BCE Herod the Great was appointed King of the Jews by the Roman Senate, but in 6 CE his successor, Herod Archelaus, ethnarch of Judea, was deposed by the emperor Augustus and his territories annexed as Iudaea Province under direct Roman administration: this marked the end of Judah as an even theoretically independent kingdom.
