"'Jew" (redirect Jewish), as a demonym, should be covered in its own article, as it's identity, and is also used derogatorily. But "Judaism" is not a derogatory term.
When the Doctor's TARDIS appeared there, Ian Chesterton and Barbara Wright joined the Jews, while the First Doctor and Susan Foreman joined the opposing Roman camp. Ian tried to change history by helping the Jews fight, which the Doctor counteracted by helping the Romans, trying to preserve time. In the end, Ian was chosen to kill everyone, and Elezar killed himself. (PROSE: The Last Days)
When Christianity came into being, the Jewish leaders — in particular the Pharisees — reacted with hostility. They tried to murder Lazarus and any one else they judged to have had contact with Jesus Christ. (PROSE: Byzantium!)
I have no doubt that they, the Jews that is, consider Christianity to be a danger to them.
In the 12th century, there existed widespread prejudice against Jews in medieval England. This largely derived from "stories you heard", with most English lords never having personally met any Jewish people. When Henri d'Arrée, returning from the Crusades, introduced his old friend Earl Godfrey to his fellow Knight Templar Moses of Tyre, D'Arrée was put off by Godfrey's dismissive treatment of him for being of Jewish origins, and by the other members of Godfrey's household unthinking propensity to refer to him as "the Jew" instead of by his name. He tried to explain the nature of prejudices to Godfrey, with little success. However, after Moses used his knowledge to save Godfrey's wife Maud from a grave illness, the Earl found new respect for him, referring to him as "Master Moses" thereafter. A short time later, Moses of Tyre semi-accidentally became responsible for the invention of gunpowder. (AUDIO: The Green Man)
In 16th century Europe, when Susan tossed a part of a Liciax ship out of the TARDIS, thinking it was a meteorite, it found its way to Prague and was shaped into a golem. When the golem went on a murderous rampage, they managed to trap it in a Jewish synagogue. (PROSE: Life from Lifelessness)
In 1938, River Song told a Nazi officer that she was on her way to a gay gypsy Bar Mitzvah for the disabled, flippantly referring to several groups that the Nazis considered "undesirable." (TV: Let's Kill Hitler)
During World War II, Jews were heavily persecuted by the Nazis, and many were sent to concentration camps. (PROSE: Timewyrm: Exodus) The word "Jewish" was used at least by the Nazis around this time derogatorily; for example, Joachim Wolff called psychoanalysis "Jewish science". (PROSE: Just War)
Amongst the other people not aforementioned who were Jewish were:
- Professor Rachel Jensen, Captain Ian Gilmore's scientific advisor. (AUDIO: Threshold)
- Julius Silverstein, businessman and collector. (TV: The Web of Fear).
- Barnabas, Jewish priest. (PROSE: Byzantium!)
- Mjovic, Sneshna, and William Jovanka, the paternal grandparents and father of companion Tegan Jovanka. (PROSE: Divided Loyalties)
Judaism was the precursor to New Judaism. The Tenth Doctor asked the Beast, if he was the Devil of New Judaism, along with that of numerous other religions, to which he responded he was the Devil of all religions. (TV: The Satan Pit)
Behind the scenes
- In the novelisation of The Web of Fear, Julius Silverstein's name was changed to "Emil Julius" in order to remove the offensive stereotype of the greedy Jewish businessman.
- One of New Zion's towns was Gehenna, (PROSE: Shopping for Eternity) probably named after the Jewish hell. There was also a planet named this, which was inhabited by Devil-like creatures. (PROSE: Mean Streets)
- Sydney Newman, considered one of the creators of Doctor Who, was Jewish, as was the show's original producer, Verity Lambert.
