Dugin myth.... I was aware of this crap artist at least 6 months ago. I do believe that sad cancerous Vlad has licked up his pan Slavic conquest teachings. Who killed his daughter? This is up in the air.
Vlad Degenerate.... The old men have their Tsarist fantasies. They send young men off to die for this rubbish.
Pan slavism is not new. It was born along with the general European Romantic movement in the 19th century.
A really good “meta” work on the phenomenon is “The Birth of the Modern”, Paul Johnson. Explains a heck of a lot. Bulky book, but very well written and completely absorbing. I totally destroyed my trade paperback copy thirty years ago.
A great part of the cause of the 19th and 20th century European wars was in the Romantic movement, pan slavism being one. For instance, it played a great part in bringing Russia into WWI.
