It started during World War 2 (the 1939-1945 war).
I wonder whether you mean something like 'Did World War 2 [not 1] hide the Holocaust?,
Yes. The Holocaust took place from 1941-1945 during World War 2 (1939-1945). The Nazis had started persecuting the Jews almost immediately on coming to power in 1933. However, the systematic gassings didn't start till 1941.
No, the Holocaust took place during World War 2. The Holocaust refers to the Nazi genocide of the Jews in 1941-1945: it is not a nickname for either of the World Wars.
The Holocaust was of no relevance whatsoever to the outbreak of either World War 1 or World War 2. It hadn't even begun ...
The Holocaust did not take place during WW 1, it was during WW 2.
The Holocaust
No. Please see the related question.

People got killed in the Holocaust because the were Jewish. Hitler (the guy who was behind the whole plan of the Holocaust) blamed the Jewish people for everything like World War 1, , the Great Depression, World War 2.
In World War 1 the Jews were not specifically targeted. Perhaps you are thinking of World War 2 and the Holocaust?
She was involved in neither.
After the start of World War II.
