Neo-Nazis are one of the main segments of the white supremacist movement in the United States and many other countries. They revere Adolf Hitler and Nazi Germany and sometimes try to adopt Nazi principles to their own times and geographic locations, though many neo-Nazis primarily adopt the trappings, symbology and mythology of the Third Reich.
