Nazi
The Nazis were a fascist political party in Germany in the first half of the 20th century. The official name of the party was the Nationalsozialistische Deutsche Arbeiterpartei, or National Socialist German Workers Party (NSDAP). It's most notable leader was Adolf Hitler, known as Der Fuhrer.
The Nazis were not in any way, shape or form conservative, despite the portrayal of it by some as a product or form of ultra-conservatism. (Of course, they were anti-abortion, anti-socialist, anti-homosexual, anti-feminist, and highly militaristic.) Rather, they were a radical movement rooted in a view of the superiority of Germany, and everything German.
Specific cultural movements eventually feeding into the rise of the Nazi Party to power included an occultism movement interested in black magic and Germanic pre-Christian pagan religion popular in Germany in the decades before WWII; and a counterculture movement of disaffected and alienated youth after WWI known as the Wandervogel, which eventually provided much of the recruitment base for the S.S. and S.A., two Nazi Party paramilitary groups.
Their hatred of the Jews eventually led to the Holocaust.
