WI: Casimir III dies in the Battle of Plowce

[kasumigenx]

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?

In 1331 Charles was already married with Blanche of Valois , so that marriage is out of the question. However, John wasn't married at the tome, so he could have married a Piast, most probably some Silesian princess. I'm not sure when negotiations between John and Philip VI started, concerning John eventual marriage to Beatrcie of Bourbon. If they started before 1331, then I think that a French princess was more attractive match than a Piast girl.

How would the Luxembourgs administer their empire, would they shift capital once they acquire Poland?

I sincerely doubt it. Not to Poland, anyway - at the time Bohemia was richer and stronger country than Poland (which was far from being united), so Bohemian-Polish union would have been dominated by Bohemia. OTOH some gestures toward Poles might have been made, e.g. Cracow made second capital or something like that.

Would the Luxembourgs want to get Pomerelia as well? would they win the Battle of Crecy with France against England?

Not against the Teutonic Order, I think, although with time they might become interested with an access to see. But not in XIVth century, IMO.
As far as Crecy goes, I doubt there would be very significant Polish presence at the battle - Poles would have had problems with Lithuanians at the time. A crusade, close to home to protect their own land - much more attractive. And John wouldn't have been able to force to many of them.
