Judaism

Judaism was one of the major religions of Earth. It was practised by the Jewish people, who spoke Hebrew.

In Masada, Judaea, a band of Jewish zealots were losing in a war against the Romans. Eleazar ben Jair, the leader of the group, devised a plan: they would all kill each other.

When the 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."

- First Doctor

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)

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)
