Poland has been a success but only during periods when it has been predominately homogenous
I disagree. It was Sarmatism that led to Golden Age of Poland. Sarmatism stimulated internal factor, sense of freedom in state, while also opened state to receive outside Balkan Serbian (Racow) influences. It all led to Golden age.
And what happened? Facing more barbarous western European societies and accepting more strict control and direct Vatican's influence, Poland was streched to its limits, moved to seek out fights for foreign intetests (crusade against Russians) , while at the same time tried to fight (against Turks) for its traditional wealth routes from Baltic to Balkan.
With time, Vatican prevailed and Poland started itd long era of servitude. Reward was internal homogenistion under Popes's cruciforma. In fact, that homogenisstion only served to strenghten presentse of Vatican and more control. Poland was turned global, while abandoned all those tiny internal differebces of past, diversity that made Poland truly great.
I'll tell you why, because diversity isn't a strength.
No, its not in Europe dominated by Vatican. Vatican had its own Interests and directed Poland that way. In that, there was no space for old inter - Slavic interests.
Not to say that Vatican always prefered Germanics.
See, silenced diversity hold Poland down and step by step moving it global.
But see, nany internal elements within Poland seek out more Serbian influence and Racowie are coming. We have our own business. Vatican, Germany and Russia have to accept that. With Russia we have a deal but other two are problem. Interestingly, even USA shows understanding. We Serbs needs free diversity from Baltic to Balkan so we can work. When free Slavs would choose new uniting factor and that is, of course awakening of Sarmatism. What else. Sarmatism is actually SUVERENISM suitable in our case.
