WI: Poland retains Silesia on the 14th Century

What if Poland retains Silesia or most of it on the 14th Century due for example, Casimir III dying in Plowce or any time before Kozyce and Bolko II of Swidnica inheriting Poland instead, what will happen to Poland and what would be its relations to other countries surrounding it?

Bolko II wouldn't inherit Poland. Since 1355 IIRC Louis of Hungary was Casimir's heir in case the former had no (legitimate) sons.

Instead of Casimir III dying earlier it'd be better to have him die later - i.e. 1382. Considering that Casimir died because of infection from hunting incident and that his father lived to the age of 72, it's quite possible. Also, just before his death Casimir was preparing for war against Luxemburgs. In this war he'd most likely have the support of Wittlebachs and Hungarians. End result: Silesia to Poland, Brandenburg to Wittlebachs nad (maybe) moravia to Hungary.

Now butterflies - with 12 yrs more to live Casimir had a chance of getting a (legitimate) son - so continued Piast dynasty on the throne of Poland. Which means no union with Lithuania, but alliance with it aginst Teutonic Order is likely. But Lithuania ITTL would still be fought over by Jogailla and Vytautas, which would weaken it; although Jogailla may end up marrying a Muscovian princess.

Another thing - with continued Piast dynasty in Poland, Pomerania remains Polish-aligned.

In the end in case of conflict between Teutonic Order and Poland, sides may be:
1. Poland, Pomerania and Jogailla's Lithuania
2. Teutonic Order and Vytautas-aligned Lithuanians
Side effect of Pomerania being on Polish side would be a lower number of Western European knights on Order's side, as they would be able to get to Order's territory only by sea - Pomerania cutting of the land road.

Further change - in case of Polish coalition victory Order loses for sure Eastern Pomerania with Gdańsk as well as Chełmno Land and possibly Elbing and other close cities. With Piast on the throne of Poland there'll be no wishy-washing of 1410-1 OTL. All in all, possible earlier end of Teutonic Order in Prussia, compared to OTL.
 
If the Teutonic Order in such a war gets into serious trouble, and with a relative lack of western knights fighting for them, Denmark just might jump the corpse trying to regain Estonia
 
There would be also no Koszyce priviledge, meaning stronger royal power in Poland. Do you think that potential Casimir III son would marry one of the Louis daughters? Let's say Catherine Survives and marries Casimir's son (let's say Vladislav), Mary Sigismund of Luxemburg and Hedwig Wilhelm Habsburg. Future of Hungarian succesion will be interesting:D, especially if Poland somehow still manages to bring Jogaila's Lithuania into her loving embrace.

I mean Casimir III dies before he becomes King or Kozyce, I think the heir of Kunigunde, Casimir III's sister is Bolko II of Swidnica.


Casimir III could also marry his Grand Daughter, Elisabeth of Pomerania to Wladyslaw Opolczyk and assign him as his own successor.

If Casimir dies before his father, the throne goes rather to one of his cousins - Vladislav of Łęczyca or Przemysl of Inowroclaw/Sieradz - sons of his uncle, Siemowit of Dobrzyn.

And not forget the designated OTL heir, to take throne after Louis of Hungary - Casimir of Slupsk, son of Casimir III oldest daughter, Elisabeth and Boguslav V of Pomerania.

I think it would be better if Casimir used his daughter, Elisabeth to find a successor instead of trying again and again to marry and sire a successor, I think a marriage between Bolko II of Swidnica and Elisabeth of Poland is possible, the rival of Casimir III married the grand daughter of Casimir III which made female line succession of his line impossible.

Have you read what I wrote? There was OTL a grandson of Casimir III - the Casimir IV of Słupsk (Stolp), born in 1351 from Casimir III oldest daughter, Elisabeth and Boguslav V of Pomerania.
 
Another issue will be that the king of Bohemia will continue to claim the throne of Poland; though that could evolve as IOTL the English and later British claim on France.

But Casimir IV of Stolp died without children, he was most likely infertile and his two wives did not sire any heir, so I think a different Husband for Elisabeth of Poland might give Casimir III a more fertile male grandson rather than the only succession via the line of Casimir III cause a possible personal union between Poland and Bohemia again due to Casimir IV being infertile.

I think ITTL Bohemia might end up being screwed ITTL.

I think Casimir III can have a son, that is if he were closer to his wife.

Actually, ITTL the Luxembourgs have a bad reproductive history, it was only Sigismund of Luxembourg that had children of all the children of Charles IV, without Charles IV marrying Elisabeth of Pomerania, it is possible that the Luxembourgs with the claim to the Bohemian throne will get extinct and the next claimants will be the family of Jadwiga of Zagan, if Wenceslaus of Mazovia is still alive he is a claimant and the Habsburgs have a claim as well.

If Casimir IV of Słupsk could have been a legitimate claimant, then why wouldn't one of his brothers be such too when he died childless?

They have different mothers that's why, Elisabeth of Poland, the daughter of Casimir III had only two children Casimir IV of Slupsk and Elisabeth of Pomerania, the mother of Sigismund of Luxembourg, I think the marriage of Elisabeth of Pomerania to Charles IV would mean that her children would have some claim to Poland which means Bohemia has a claim to Poland again, I think Casimir III should have not married her to his enemy but rather to a trusted vassal that could succeed him.
