The Jewish War or Judean War (in full Flavius Josephus's Books of the History of the Jewish War against the Romans, Greek: Φλαυίου Ἰωσήπου ἱστορία Ἰουδαϊκοῦ πολέμου πρὸς Ῥωμαίους βιβλία, Phlauiou Iōsēpou historia Ioudaikou polemou pros Rōmaious biblia), also referred to in English as The Wars of the Jews, is a book written by Josephus, a Roman-Jewish historian of the 1st century.
Divided into seven books, it opens with a summary of Jewish history from the capture of Jerusalem by the Seleucid ruler Antiochus IV Epiphanes in 164 BC to the first stages of the First Jewish–Roman War (Book I and II). The next five books detail the unfolding of the war, under Roman generals Vespasian and Titus, to the death of the last Sicarii. The book was written about 75 AD, originally in Josephus's "paternal tongue", probably Aramaic, though this version has not survived. It was later translated into Greek, probably under the supervision of Josephus himself.
