NO world war I NO Adolf HItler. The Nazi's made great use of propaganda. Remember, he said the first war was lost due to what he perceived as better allied propaganda. The Nazi's used the MEDIEVAL city of Nuremberg as the center of much of their mass gatherings. The glorification of German glory, it's MYTHS, it's idea of "Volk" (german people) german warriors (romantic, medieval) they even referred to the their nazi regime as the Third Reich(first one w charlemage---Medieval which became HRE, 2nd Reich Kaiser)

 

He loved the theatre, especially those which glorified german heritage and his favorite composer was Wagner (who by the way was a total anti semite, too.) Wagner composed romantic, powerful orchestrations depicting German themes, medieval and mythical. 

 

Assembly Line...a tool utilized by many in the 1920's, including in the USA henry ford. The assembly line will be utilized in the 20's, 30's to help mass produce the weapons of war like tanks, planes, grenades, etc. The assembly line will ALSO be used for mass murder. The Nazi death camps, (Concentration Camps) were essentially assembly line killing methods.
