Even if the Netherlands revolt earlier... they are not yet religiously divided, so they might revolt together, but still: The Northern Netherlands could manage it with the usual tactic of strategical flooding of land, but the Southern Netherlands, even if supporting attempts at independance, could be less fortunate...
The Netherlands seemed able to maintain their unity in the face of the Burgundian dukes, and the French King at the time of Philip I (the Handsome)'s death, Louis XII, was heavily involved in Italian affairs, attempting to secure his hold on Milan.
Since Louis is so involved in Italy I don't know that he has the resources or desire to turn that attention north to the Burgundian Inheritance. If he does leave Italy to go to war in the Burgundian Inheritance, then Italian history will be very much changed with the sudden withdrawl (not defeat) of French forces.
Hm. Looking up who has dynastic claims to the Burgundian lands... Charles the Bold had no surviving siblings, but some aunts. The oldest of them married a Cleves, so the House of Cleves would have a dynastical claim. Which is right around the corner, but of course not actually powerful. Still, they could ally with the Netherlandic estates and burghers... and the new HREmperor (if it isnt the French King himself) would surely not want France to gain the Netherlands, either...
The other possibility is one of Charles the Bolds half-brothers. His father Philip the Good fathered many bastards, apaprently. The oldest one was named
Antoine, and had a family himself... which could also raise a claim.[/quote]
Antoine not only had a family, he had been legitimized in 1485 by Charles VIII (OTL). Now he died in 1504, but under the conditions of this scenario Philip the Handsome has had no children, so his legitimization is much more important. Antoine played a key role in the marriage of Maximilian and Mary of Burgundy, so perhaps his children (wikipedia has no information about them) become the compromise candidate between Maximilian and Louis XII?
As for the Wettins, at that time their lands were still evenly divided between Albertine and Ernestien branch, so thats a hinderance. The senior Ernestine branch has the electorial dignity, but the Albertines have with Dresden, Leipzig and the Ore Mountains the richer lands...
Actually, Albert IV of Bavaria had already finished a war against the heirs of Duke Geroge of Bavaria, in which Albert IV managed to reunite Bavaria. So that is not an issue.
The bigger issue is going to be Margaret of Austria. Her brother Philip is dead, so she now inherits the Burgundian Inheritance. Her father Maximilian supports her, so it shouldn't be too much of an issue with France, which is occupied with a war in Italy. Now Margaret had sworn never to marry following the death of her second husband the Duke of Savoy, but now that she is the Duchess of Burgundy and stands to inherit the Duchy of Austria and other Hapsburg familial land I think that she is going to have to marry. She is 26 years old, and had a still-born child with her first husband. So who is Margaret of Austria going to marry?
He furthermore was married to Maximilian's sister, so since Philip is childless and dead when Maximilian I dies in 1516 (assuming he continues childless), then Duchess Margaret of Burgundy's husband, being married to the vast Hapsburg inheritance, will probably be the next Emperor. If Margaret and her third husband end up childless, then William IV of Bavaria (Albert IV's son) stands to inherit the Austrian part of the Hapsburg realm, and might be able to get Burgundy. If Maraget and the third husband do have child, and it is male and has reached its majority prior to its father's death, then the Hapsburg-(whatever the third husband's dynasty is) Dynasty continues to rule.
As for a suitable third/fourth wife for Emperor for Maximilian... Its a conspiracy, I tell you! All roal or electoral houses have daughters born in the 1480s (already married in 1510) or 1500s, but not the 1490s... One I could find, though: Elisabeth, born 1494, daughter of the Duke of Lüneburg. Ironically, IOTL married to Habsburgs Enemy Charles of Guelders, but that was 1519, after Charles V. had intervened against Lüneburg in some feud... Hm, yes, Elisabeth of Brunswick-Luneburg might be good...
Find Maximilian a wife, and find Margaret a husband more importantly.
The Elector of Saxony, Frederick III is a potential husband, (he was the Pope's candidate for Emperor OTL when Maximilian I died) as was his brother (and successor) John.
Henry VIII?
