Your challenge: with a PoD no earlier than 1000AD, have Poland conquer the entire world.
By this I mean, at minimum Poland has total domination over the globe, in a similar way to Britain in the 19th century. At maximum, Poland has completed a total conquest of all of the planet, either by direct control or vassals and allies.
Poland should have no remaining major rivals capable of challenging it for power. Other nations can exist, but they should be either too weak to have a chance of overthrowing Polish dominance, or they have been defeated at some point and vassalised, or they are under Polish influence politically and or economically.
Possible?
