Francis Parker Yockey was an American fascist, Pan-European and ideologue best known for his neo-Spenglerian book Imperium, published under the pen name Ulick Varange in 1948. This 600-page book argues for a race-based, totalitarian path for the "preservation of Western culture". Although best remembered today as a writer, Yockey was active with many far-Right causes around the world throughout his adult life until his suicide in FBI custody in 1960.
