Scenario: A pan-Slavic stellar colonization effort launches from Earth. A hundred years later, I arrive to discover that there's a population crisis---all the women (gorgeous, delicious, succulent Slavic women...mmm) think those Slav dudes are too ugly and kielbasa-brained to breed with, and they want something a little prettier...like an ethnic French guy from Earth. Likewise, their government has broken down because Russians haven't gotten government right in a thousand years of trying and this has followed them into space. They decide, thanks to some history books an intellectual smuggled on the original space voyage, that an Enlightenment-era Western European monarchy is in order, and who better to be the king than someone descended from those Western Europeans? So I'm King Fox.
Using my charisma and charm, I manage to convince the girls that the king's mistresses were an integral part of the stability of the monarchy and show them some stuff about Persian sultanates and say "some of those sultans were great rulers and they all had harems, what say we try that here?" Since the women's other choices would be to go with Ivan the Borscht Face, they're like "sure!"
I spend the rest of my life instituting state-capitalist policies and enjoying copious amounts of copulation with smokin' hot love Slavs.
