20 Legions Explained | Real Life Inspirations

This video explains all 20 Space Marine Legions in Warhammer 40k and the real life inspirations behind each one. Every Legion traces back to an actual historical event, myth, or culture, from Ancient Rome and Norse Vikings to Cold War espionage and WWI trench warfare. The two Lost Legions get their own explanation too, tracing Legion II and Legion XI back to a real Roman military disaster at Teutoburg Forest. Each Legion covers the specific historical or mythological source. This is for Warhammer 40k lore fans who want the real history and mythology behind the Legions instead of surface-level trivia.
