The term "Judaism" derives from "Iudaismus", a Latinized form of the Ancient Greek "Ioudaismos" (Ἰουδαϊσμός) (from the verb , "to side with or imitate the "). Its ultimate source was the Hebrew יהודה, "Yehudah", "Judah", which is also the source of the Hebrew term for Judaism: יַהֲדוּת, "Yahadut". The term "Ἰουδαϊσμός" first appears in the Hellenistic Greek book of 2 Maccabees in the 2nd century BCE. In the context of the age and period it meant "seeking or forming part of a cultural entity" and it resembled its antonym "hellenismos", a word that signified a people's submission to Hellenic (Greek) cultural norms. The conflict between "iudaismos" and "hellenismos" lay behind the Maccabean revolt and hence the invention of the term "iudaismos".
