Can it be done? Or is it ASB?
Including the parts in Poland, Germany and Czech Republic.
Let's say that the POD is in 1900.
It is possible with a POD in the Medieval times around 1100-1300 with a Silesian Piast being able to unite all Silesia under his trone and being able to obtain formal international recognition as :
- a royal crown from the Pope,
- an Electorate title from the HRE,
Because he was able to defeat a Mongolian invasion for exemple ???
But a POD in 1900 is rather non possible, limit ASB, as Silesia is only a small territory between large nation : germans, polish and czech nations, and a big part of the Silesians felt rather german or polish than silesian...
