Book Burnings, just like the Nazis did
Also extensively done in the USA in 1917 as part of a deliberate fed directed program to excite hatred for all things German. Thousands of volumes by German authors such as Kant or Heine or just about Germany were publicly incinerated. In St Louis the very valuable special collection of German language books was burned in front of the main city library. All to whip up war fervor because the government knew there was substantial anti war feeling in the general population.
