By the time Nazism arose in Germany in the 1930s, anti-Semitism was nothing new -- not by a long shot. The Jewish people had suffered a long history of prejudice and persecution. And although Nazis perpetuated centuries-old lies, this time those lies would have their most devastating effects. Like never before, anti-Semitism was manifested in a sweeping national policy known as "the Final Solution," which sought to eliminate Jews from the face of the Earth.
To accomplish this, Adolf Hitler and his minister of propaganda, Joseph Goebbels, launched a massive campaign to convince the German people that the Jews were their enemies. Having taken over the press, they spread lies blaming Jews for all of Germany's problems, including the loss of World War I. One outrageous lie dating back to the Middle Ages claimed that Jews engaged in the ritual killings of Christian children and used their blood in the unleavened bread eaten at Passover [source: Landau].
Using Jews as the scapegoat, Hitler and his cronies orchestrated what they called "the big lie." This theory states that no matter how big the lie is (or more precisely, because it's so big), people will believe it if you repeat it enough. Everyone tells small lies, Hitler reasoned, but few have the guts to tell colossal lies [source: Hoffer]. Because a big lie is so unlikely, people will come to accept it.
This theory helps us understand so many of the lies throughout history. Although we've barely scratched the surface of all those lies that deserve (dis)honorable mentions, you can satiate your historical curiosity by browsing the lists on the next page.
