What if the Poles were defeated in the Battle of Plowce and Casimir III dies in the Battle of Plowce against the Teutons, if he dies it means that John of Luxembourg will be able to rule Poland with the support of Masovia and Silesia, who recognize him as the King of Poland.
How would the Luxembourgs administer their empire, would they shift capital once they acquire Poland?
Would the Luxembourgs want to get Pomerelia as well? would they win the Battle of Crecy with France against England?
