How has propaganda been used in regards to the holocaust?

Hitler and Goebbels did not invent propaganda. The word itself was coined by the Catholic Church to describe its efforts to discredit Protestant teachings in the 1600s. Over the years, almost every nation has used propaganda to unite its people in wartime. Both sides of World War I used propaganda. But the Nazis were notable for making propaganda a key element of government even before Germany went to war again.

One of Hitler’s first acts as chancellor was to establish the Reich Ministry of Public Enlightenment and Propaganda, demonstrating his belief that controlling information was as important as controlling the military and the economy. Through the ministry, Goebbels was able to penetrate virtually every form of German media, from newspapers, film, radio, posters, and rallies to museum exhibits and school textbooks, with Nazi propaganda.

Many people disagreed with this kind of living so this forwarded Jews to concentration camps for disagreeing with their "fuhrer" ways of life.  

it wanted to boycott trade with enemy nations.
