It is truly all about German/Nordic business men. Hundreds of years before the World Wars German/Nordic elite infiltrated and took control of all the royal families. They primarily focused on social engineering, and currency manipulation to trick the people to overthrow their own kings and queens.

Once they controlled Eurasian empires they proceeded to invade the south but the crusades failed because the southern humans already have been conquered by elite families who had spies in the north and generally already knew how the game worked.

They didn't expect the Eurasian empire to conquer the Americans but they played a mean ruse for along time. Built the American Empire and the Eurasian empire conquered the world.
