I did a few of these landmasses myself, including an 'Antillia' proposal and the 'Meridian Archipelago' of the coast of Southern Africa.
Big fan B_Munro. Love Polish Texas but don't you think a full Germany incl. Austria would be free of the Polish yoke?
Surely you can spring for a Polish Constantinople, no?
Also, couldn’t the other West Slavs, the Czechs and Slovaks, been Polonized under the right circumstances?
That Russia's too damn big. I can see Poland, Mongolia and Manchuria. They're remote enough and far away from other Great Powers to make the conquests relatively uncontested. Everything else is super reaching. What's the history of this world?
EDIT: Oh it's an Nationalist-Reactionary Tsardom in a polarized world. Bleh. Better than Nazism, but still.
Good, good...I dunno: I think it needs a bit more Poland. What do you think?
