The Bystander Effect is a psychological term for the tendency for people to be less likely to help victims in need when other people are present. During the Holocaust, a significant number of people around the globe knew about the mass murders, deportations, and concentration camps, and yet did nothing to help the victims. Why? What made people more (or less) likely to step up and help?
The fighting may have ended in 1918, but the Treaty of Versailles negotiations in 1919 may have been just as important. Woodrow Wilson’s noble ideas like “self determination” and “fair and lasting peace” didn’t amount to much as the Allied powers sought mainly to punish Germany. A continued naval blockade, the war guilt clause, reparations, and exclusion from the League of Nations helped put Europe on the path to World War II.
