Jews

Jews' (shortned form of "Judeans") are an ethnoreligious group which descend mostly from the Biblical Israelites of Israel, and other people amongst whom they sat in exile and admixtured with (mostly as converts to Judaism, their national religion). They're the nation/ethnicity of Jesus Christ, Kyle Broflovski and his family, and the South Park Jewish Community.

They're frequently mentioned in the series, mostly by Eric Cartman who mocks them in racist manners.

History
The Jews' ancient roots are in the Iron Age era's Kingdom of Judah and the remnants of the Kingdom of Israel who assimilated into them following the Assyrian destruction of Israel in 722/1 BC; they were later exiled by the Babylonians who destroyed their 1st Jewish Temple to Syria, Iraq and Iran in 2 phases between 597 and 586 BC. But were allowed to return to Israel and re-establish their ancestral homeland once Cyrus the Great was in throne in 538 BC, this time renaming it "Province of Judea".

They maintained their national homeland, through times of severe despair such as the destruction of their 2nd Jewish Temple in 70 AD, till 135 AD when they were stipped off their national rights by the Roman Empire, that also exiled many of them as slaves to Europe and North Africa. They were later subjected to the cruelty of the Byzantine Empire which opted to convert them all to Chrstianity, thus starting to migrate elsewhere to pagan lands.

In 1948, the modern State of Israel was established, and the Jews had returned in their majority to live in the Land of Israel.
