What if Elisabeth Richeza never became the Queen Regnant or Female King of Poland, this means we will have no Hedvika of Bohemia that christened Lithuania and Anne of Bohemia, Queen of England since both were grand daughters of Elisabeth Richeza..
What if Vladislav the Short who was defeated by the King of Bohemia and his son, Stephen who was tonsured as a priest became Kings of Poland, how would they rule?
And we would never have seen the realm that Premyslid and Vasa Monarchs ruled in Central Europe.
Would we still see the Hussite Revolt and the Hussite sympatizing Monarchs happening in Poland and Bohemia which in OTL led to a large minority of Protestants in the two countries, would the Habsburgs still try to mess with the two countries?
