I pretty much was - but that's OK
Post by Alex MilmanPost by The Horny GoatHow about a Gustavus Adolphus fantasy scenario where he doesn't die
early?
His resources had been too limited for the task and he hardly could keep much more than the coastal areas of Baltic Sea.
But if you are talking about the 30YW how about more successful Wallenstein. Unlike GA, the Emperor and pretty much everybody else he had at least some "imperial idea" and prior to his forced retirement managed to establish imperial control over a big part of Germany (including the Catholic states) and presumably had over 100K troops. If he had a consistent support from the emperor, he could continue the process strengthening the imperial power to a degree excluding a serious contest. Of course, it would help if this was accompanied by an early death of Cardinal Richelieu and by GA's death (instead of just a wound) during the Swedish-Polish War.
Well Alex, what does maximum Wallenstein success look like? Imperial control of all imperial territory? Reduction of the effective sovereignty of the non-Habsburg princes of the HRE's states to the level enjoyed by say, Bavaria, in the second German Reich?
This would be too much to expect but he could achieve an overall imperial supremacy on a big part of the HRE up to a degree making effective military resistance unlikely. He was reasonably close to this, which made the imperial princes unhappy enough to demand his resignation in exchange for supporting the Hapsburg imperial succession. Basically, the mistake was the same as one that latter resulted in a War of the Austrian Succession: the Hapsburgs believed in a "due process" more than in military strength (in OTL Prince Eugene told the emperor that the money he spent on confirmation of the Pragmatic Sanction would be better spent on maintaining an army 140K strong; true to his statement, when this piece of paper proved to be meaningless, Austria had no army).

With some adjustments related to the Church property the Hapsburgs were reconciled with an idea of having the Lutheran states.
The French parallel is not applicable: France was an unified kingdom while in the HRE we are talking about almost independent German states.
Post by RobAn HRE colonial and trading company and navy?
Wallenstein was trying to build imperial navy and had a title "Admiral of the North and Baltic Seas" but he failed to take Stralsund which denied him access to the Baltic and the chance of challenging the naval power of the Scandinavian kingdoms and of the Netherlands.
Post by RobWould the HRE be able to avoid a final settlement allowing Swiss and Dutch independence, the way that Westphalia did?
The Dutch independence was Spanish business.
Post by RobWider conquests?
Is strong and consistent support from the Emperor all that Wallenstein needs to kick ass?
Not only but this was critical because he was deprived of his command just when he build up a big army (allegedly up to 100K) and organized weaponry production on his own territories. He would need to work on organization and discipline of his troops but he already had at least a framework of the financial backup by forcing the imperial territories to pay.
He was not a brilliant tactician like GA but he was most probably a better strategist (at least Filedmarshal Montgomery thought so).
His cavalry definitely need a tactical improvement: unlike the Swedish cavalry, it was still relying upon the firepower and caracolle.
Infantry was seemingly using a slightly outdated tactics but was generally up to the task.
Artillery was inferior to the Swedish both numerically and in quality (and I'm not sure that he had a mobile artillery at all).
But with all these drawback and with a brand new army he had to create after being recalled from his retirement he managed to defeat the bigger army of GA in the Battle of the Alte Veste.
Post by RobPost by Alex MilmanSpain, while having for a while the best army in Europe, had been plagued by a systematic shortage of money which did not allow to have enough troops in the field for even crushing the rebellious provinces.
France would be a candidate in the early-modern times providing: (a) it does not have OTL internal problems and (b) it starts creating a modern national army well before OTL time frame and (c) it manages to make that army comparable in numbers to the armies of French Revolution and (d) it produces capable commanders with of "Napoleonic" style (not necessarily with his talents, just with his approach). At least France was the biggest (in population) and economically developed European state which in OTL by the late XVII could be balanced only by a coalition of other states.
That is a lot of things that have to go right,
Well, you are asking for a lot. :-)
Post by Robbut I would think it would be the #1 prospect.
Actually, this would not be completely unrealistic. Creation of the French national army could start few decades earlier, for example during the reign of Henry IV or early in the reign of Louis XIII. It could start noticeably earlier even in OTL-like conditions because Richelieu started its creation only when he tried all the wrong options. His initial idea was NOT to create a French army but rather subsidize all anti-imperial forces. So he wasted a lot of money first on supporting the adventurers like Count Mansfield (who in "gratitude" looted the French territory when he was kicked out of Germany) and all the way to GA and his military successors who would take the money and then pursue their own goals. Then he hired an army of Bernard of Weimar (after he died) but the troops took money and went their way. Only when he run out of the available bad options (and found that there are no troops to defend France in the case of invasion) he slowly proceeded with building up a regular army based upon the national resources. Of course, true to his general pattern, he put it under command of the Duke of Enghien (future Great Conde) who was married to his niece and proved to be a great tactician but had no taste to the boring administrative and organizational work leaving it to the subordinates. Every winter (when the fighting season was over) he was abandoning his troops to travel to Paris and its entertainments.
Richelieu would do much better by giving this position to Turenne who was a REAL general in all necessary aspects (not surprisingly, during the Fronde, the troops had been following him rather than Conde).
As a result, by the time Louis XIV started his de facto reign (after regency of his mother was over) he inherited a mess and it took years to convert it into the most powerful army in Europe but it was slightly too late (or too early :-)).
In ATL France could have a powerful army on the early stages of the 30YW when the situation was very close to a power vacuum. The only serious military competitor would be Spain but, if a new French army was created with the usage of the existing Dutch experience and using the French economic advantages over Spain (ability to produce more firearms with a resulting greater firepower of the troops AND an ability to pay regularly), this issue could be resolved rather fast (with the help of the Dutch troops) leaving France the biggest bully in the Western and Central Europe.
Note that the "social conditions" in France changed little over this time span so there was no valid reason for NOT starting recruiting the French nationals much earlier.
Post by RobYour conditions are important ones. Some things that could give France a boost along the way could also be if they inherit all the Burgundian lands as a block, with none going to the Habsburgs.
Would be nice but not really necessary: Louis XIV managed to create the most powerful army in Europe without this condition.
Post by RobOr, if they are the first to grab New World gold and silver.
They did not need anything of the kind: in OTL Charles V, with all his American gold and silver had been routinely running out of funds earlier than his opponent, Francis I.
