(sorry for my English)
As is known, in our reality, the king of Bohemia and Hungary, the Archduke of Austria Ladislaus the Posthumous died in 1457 from leukemia, and on the eve of his wedding, thus not having time to leave descendants. With his death, the Albertine Habsburg line was interrupted.
But let's imagine what would happen if Ladislaus the Posthumous were not sick with leukemia. Of course, even without this terrible disease, his health would be very fragile, but he would be able to live up to about 30 years (ie, until 1470), and, accordingly, he would be able to marry and acquire heirs. So…
In January 1458, a planned wedding takes place between Ladislavolm Postum and Madeleine Valois, the result of this marriage will be the birth of three children - a son - Louis (1460-1505), and daughters - Catherine (1462 - 1511) and Elizabeth (1466 - 1503).
In domestic and geopolitical terms, the consequences are more than serious. Firstly, the freedom of Matthias Corvinus in this world does not shine, for he was released from prison only by the sudden death of Ladislaus the Posthumous, and he lives and flourishes here. Consequently - Matthias Corwin in this reality here will be quietly killed in prison. However, Ladislaus and his heirs will still have to pursue roughly the same domestic policy that Matthias pursued in our reality (army reform, restriction of the power of the big feudal lords). The fact that Ladislaus is much less ambitious than Matthias is even a plus, because Matyash’s exorbitant ambitions, with all the grandeur of the latter, have done a lot of mischief (say, I strongly doubt that Ladislav betrayed Vlad Tepes). In addition, in this world there will definitely not be a Bohemian war, therefore, the resources of Hungary, Bohemia and Austria are not wasted on this conflict, but launched against their common enemy - the Ottomans. Of course, if the campaigns on the Balkan Peninsula are not very successful, the Turks will not be allowed to go beyond the Danube, and Transylvania, Moldavia and Wallachia in this world will be free from Ottoman rule (and will be allies of the triune Bohemian-Hungarian-Austrian monarchy)
It is clear that Vienna and Linz remain here for the Albertine Habsburg line, while the possessions of the Leopoldine line will be Tyrol, Styria, Carinthia and Carniola.
Moreover, since in this world the king of Poland, Casimir IV, cannot even dream of either the Bohemian or the Hungarian crown for his eldest son, firstly, it changes the balance of the Polish-Lithuanian throne inheritance (the heir of the Polish throne will be Vladislav, and Lithuanian heir - Jan Albrecht), which in turn changes the situation with their marriages. Also, Casimir Polsky will obviously take care of the fact that, in the absence of his prospects in the succession of Bohemia and Hungary, he will secure his sons (the younger ones, Alexander and Sigismund) in Silesia by entering into corresponding dynastic marriages.
Since Madeleine Valois is the wife of Ladislaus the Posthumous, then Gaston de Foix, Prince Vian, will get another wife, Bona of Savoy. The result of the marriage of Prince Vian and Bona of Savoy will be the birth of three children - sons - Francis (1466 - 1522) and Jean (1467 - 1505), and daughter - Eleonora (1469 - 1507)
In turn, due to the alternative marriage of Bona of Savoy, the other wife will also be with Galeazzo Sforza - Barbara Gonzaga, with marriage to which Galeazzo will have only one daughter who died in infancy, will become her. Thus, already in 1476, Lodovico Sforza will get the throne of Milan (which in the future sharply reduces the likelihood of the very onset of reasons for the Italian Wars)
Also, an alternative marriage will be in Saxony. For who is in this world Sidonia Podebrad, so that he becomes the wife of Albrecht III of Saxony? Sorry, but he will not marry a daughter, albeit an influential but specific feudal lord. In this world, his wife will be Agnes Nassau-Weisbaden, and since she had no offspring with her offspring, in this world the division of the Saxon house into the Albertine and Ernestine lines will never happen.
On March 22, 1470 Ladislaus dies, his successor is his 9-year-old son Louis, the regency under which goes to his mother - Madeleine Valois.
In 1476, Louis Habsburg is declared an adult, which is supported by his wedding with his cousin - the Polish princess Sophia. The result of the marriage of Louis and Sofia will be the birth of the following children:
Ladislaus (1480 - 1488)
Elizabeth (1482-1482)
Sofia (1485 - 1544)
Catherine (1486 - 1540)
Albrecht (1489 - 1567)
Barbara (1493 - 1556)
Sigismund (1496-1502)
Ferdinand (1498 - 1563)
Meanwhile, the conflict over the Burgundian inheritance begins, and Louis Habsburg, given that his father is Habsburg, and his mother is Valois, in the most literal sense, "it is written to become" to mediate between Maximilian Habsburg and Louis XI. And the fact that there is a powerful Hungarian army behind Louis Habsburg’s back will be an additional argument in his mediation position ...
