Hello There,

Please have a look at the discussion between myself and u/Aethelric [here] (https://www.reddit.com/r/AskHistorians/comments/51kf5q/from_what_ive_read_the_thirty_years_war_killed/d7df7wa). It may give you a better idea of the historiography and the different debates presented by historians.

Your professor's assertion falls under the theory the war was about the centralisation of power under the direct control of the Habsburg monarchy, over the particularisms of the Estates. But Aethelric does a pretty good job to underline some inherent faults with such a claim.

Your professor is repeating a completely spurious and ahistorical claim. /u/ErzherzogKarl already linked to a discussion I just had on the topic of the TYW, so I'm going to refrain from going too deeply here and just try to give you the gist of the dominant narrative for the War's start.

So, by 1618, the Protestant Reformation had split the Holy Roman Empire (and Europe more generally) into roughly three camps: the Catholics, the Lutherans, and the Calvinists/Reformed Christians. The latter two would work together against the Catholics at times, but held a deep distrust for one another.

The war itself began, as your professor rightly asserts, in Bohemia (a kingdom comprised of the lands of the modern-day Czech Republic, mostly). However, the silver mines were never a precipitating cause. The largest precipitating cause of the Revolt was one primary fear: that Catholic ruler of Austria, Ferdinand II, would convert the nobility of Bohemia (who were >90% non-Catholic) to Catholicism just as he had Lower Austria when he took the throne of Bohemia. Once the Revolt began, the Bohemian rebels began eagerly seeking out a Protestant prince to take the throne—most refused. However, the Calvinist Frederick V of the Palatinate finally accepted the crown and led the rebellion, hoping at once to remove the Habsburgs from Austria and become the first Protestant Holy Roman Emperor. He took this role because, by all accounts, he believed that he was fulfilling an important esc

Frederick V failed miserably, which likely would have been the close of the conflict had Ferdinand II not chosen to chase Frederick back into his lands and seize them, giving them to the Catholic side of Frederick's dynasty in Bavaria. This seizure and Ferdinand's open desire and apparently ability to reconvert all of the Holy Roman Empire to Catholicism opened up the conflict to the brutality of its size.

By the time the war was really being fought in earnest, no one particularly cared about the Czech lands at all, much less its mines! England and Denmark, the first two outside powers to enter the conflict, were much more concerned with protecting other Protestant princes than about the religious rights of the nobility in Bohemia.

tl;dr The conflict was largely a struggle by land-owning aristocracy and princes over what religion should be practiced in Bohemia (and who should rule, as a necessary extension of the question), and then snowballed into a general conflict over the fate of Protestantism in the entire HRE and beyond. By the time the war ended, France joined to reduce Habsburg hegemony. At no point did anyone talk about or seem particularly interested in silver mines (looting armies excepted, of course).

My main source here is Peter Wilson's The Thirty Years' War: Europe's Tragedy. I cite it a lot, I admit, but it's easily the best work available that covers the entire topic. If you want to learn more, please consider picking it up!

It's very good to be skeptical of your professor's claim. I'd like to add some further perspective of what /u/ErzherzogKarl /u/bemonk and /u/Aethelric already wrote here and in the other threads.

In the 1600s there was no concept of separation of church of state. So on one hand, arguments can be made that the two are very intertwined. But on the other hand, one cannot simply say that one concern overrode the other through compartmentalization. This is what your professor made a mistake in.

If we are to focus on particularisms arising in that era, and the empowerment of estates in Bohemia and Austria, then those were enablers of a religious revolt, not the direct nor only cause of a revolt. Bohemian nobility and estate had been granted a high degree of independence in religious affairs due to the critical need for funds in defense against the Ottomans. Estate taxes from Austrian and Bohemian lands accounted for just about 60% of the funds used to fight that the Long War.

In 1575, Maximilian II gave oral sanction to the Bohemian reformation. Then in 1609 Rudolf II wrote a formal letter of majesty, allowing Bohemian nobles and estates to establish their own institutions -- secular and ecclesiastical -- in parallel and in conflict with the legacy structures. So the structural changes in Bohemia was directly due to religious conflict, the same rights that many Bohemian nobles feared they would lose under the incoming Emperor Ferdinand II.

When rebellion did break out, these rebels sought the help of the Protestant Union of German states, even if they had acted independently of it.

The aftermath of the Bohemian rebellion in 1620 was indeed due to Habsburg management of their resources -- including the alliance of Protestant powers -- enabled by their arguing that the revolt was against public peace (and thus downplaying the religious aspects). But this is how the Habsburgs wanted to present the situation, not necessarily accurately. Even contemporaries saw it as a religious revolt, thus making their next moves toward a larger war. If anything else, comparing the situation in the German parts of the HRE with that of Bohemia, it can be argued that the further centralization and institutionalization there (through Reichstag assemblies, kreis system, et al.) succeeded in preventing outright rebellion that happened in Bohemia!

Wilson's Thirty Years' War book is fantastic but to further understand the dynamic of the HRE I recommend his newer The Heart of Europe. I also like Parker's own Thirty Years' War.
