Holocaust
From Tardis Wiki, the free Doctor Who reference
The Holocaust was the industrialized genocide of the Jews and others considered "undesirable" by the Nazi Party during World War II. (PROSE: Timewyrm: Exodus)
Grigori Rasputin planned to prevent the Holocaust after receiving a vision of the future, but the First Doctor removed his knowledge of it. (AUDIO: The Wanderer)
The Seventh Doctor listed the Holocaust as one of the terrible things that happened after he set history back on track by freeing the Timewyrm from Adolf Hitler's mind. (PROSE: Timewyrm: Exodus)
