The Roman province of Judea (Hebrew: יהודה, Standard Yehuda Tiberian ; ; ; ), sometimes spelled in its original Latin forms of Judæa, Judaea or Iudaea to distinguish it from the geographical region of Judea, incorporated the regions of Judea, Samaria and Idumea, and extended over parts of the former regions of the Hasmonean and Herodian kingdoms of Israel. It was named after Herod Archelaus's Tetrarchy of Judea, but the Roman province encompassed a much larger territory. The name "Judea" was derived from the Kingdom of Judah of the 6th century BCE.
