Introduction

The early modern Habsburg Monarchy is an interesting playground for mining historians.  This particularly applies to the period after 1526, when the Habsburgs incorporated the medieval kingdoms of Bohemia and Hungary and thus brought some of the most important mining regions in Central Europe under their rule: Tyrol, the Bohemian Ore Mountains and the Slovakian Ore Mountains. 

To research the early modern mining history of the Habsburg Monarchy, historians must almost become miners themselves. Just as miners must make their way through complex geologies, historians have to fight through complex archival strata and mountains of records, whose histories have produced extraordinarily diverse layers of sediment and deposits of documents in diverse places. Through their search for the rich ores – the important sources for answering research questions – historians must understand the “complex geology” of the archives. This applies in particular to former Habsburg records, which are today distributed among different nation states and their associated collections. In this blog post, I want to shed some light on this complex geology and point out potentially interesting deposits, focusing on the Hungarian documents in the Austrian State Archive in Vienna.

Of sedimentation and tectonics shifts

The 1520s were important years for the Habsburg Monarchy. Politically, the Habsburgs enlarged their territory after the battle of Mohács in 1526 by the Kingdoms of Bohemia and Hungary and Ferdinand I. established the “Hofkammer” in Vienna as the basis for a centralized financial administration in 1527. The establishment of the “Hofkammer” laid also the foundation for one of the most important repositories of records for Habsburg mining Historians – the “Alte Hofkammerarchiv”. [1] Why? As almost everywhere in pre-modern Europe, precious metal mining areas were legally considered as royal estates (Kammergut) of kings and queens. This means that they had direct control over them and were therefore one of their central sources of income. 

Furthermore, the provincial chambers (Lower Austrian, Upper Austrian, Bohemian and Hungarian) were also subordinate to the Court Chamber as central administrative units. The mining administrations were located one level lower. Over the centuries, thousands of pages of archival material with mining-related content also accumulated in the “Hofkammerarchiv”. 

This sedimentation within these areas did not remain stable however. The territory of the early modern Habsburg Monarchy was repeatedly subjected to tectonic upheavals, which affected the structure and contents of the archives as well. The biggest shifts occurred during the 19th and 20th centuries, when national movements, the collapse of the Habsburg Empire, the first and second World Wars and the Cold War changed the archival landscape. The multinational and polyglot territories of the Habsburg Monarchy were particularly affected.  

Especially the central eastern Europe part containing territories of today´s Hungary, Czechia, Slovakia, Romania, Ukraine, Serbia, Croatia, Slovenia and Austria. That’s why records from the former Habsburg court chamber system came to be distributed across newly independent nations that once made up the Habsburg empire. Nevertheless, a significant volume of the imperial archive remained in Vienna, but some are also located in the Austrian provincial archives due to leftovers but also to politics of redistribution. Others, for example the former Bohemian Chamber now is in the State Archives in Prague. However, a peculiar situation arose regarding the Hungarian files.

Hungarian ore veins in Vienna

Many of the deposits of the Hungarian “Hoffinanz” of the former Habsburg Monarchy are now located in the Austrian State Archives in Vienna, meaning that particularly rich archival deposits relating to early modern mining can also be found there. The reason for this is the compromise of the Baden Archives Agreement of 1926, in which Hungary agreed to leave the files of early modern Habsburg-Hungarian´s joint organisations [2] Vienna. In return, Hungary sent archive delegates to Vienna to assist with the cataloguing and administration of the joint records, which is a full-time position since 1926. [3] But organising research stays was complicated, even though the materials were in the same location. Past archival practices are hidden behind the modern appearing of the digital finding aids. To navigate and research through the inventories needs some sort of understanding of these practices. 

The most productive veins the mining historian can find are in the “Hungarian Court Finance”, where there is a huge selection called: “Ungarisches Münz- und Bergwesen”. But a lot of important documents are also located in the “Vermischte Ungarische Gegenstände”, a selection which emerged due to early modern archival practices. Therefore, these inventories follow an early modern logic and are chronologically sorted. Mining historians have to really dig into their depth to find their treasuries because an interesting account book from 1656 could be somewhere in the files from this year. But in the 1656 Box there are ca. 500-1000 other documents sorted from January to Decembre. 

Regarding the Lower Hungarian Mining Towns there is also another curiosity to be aware of. Certain records could be kept in the inventories of the Lower Austrian Chamber. The Habsburgs placed the administrations of the seven Lower Hungarian mining towns (today's Slovakia) under the control of the Lower Austrian Chamber (with its residence in Vienna and thus geographically close to the Court Chamber).  This was probably intended to strengthen control over the extraction of precious metals.

Other possible repositories were produced because of 19th century archival practices and are now located in the “Haus-, Hof-, und Staatsarchiv (HHStA)”, which could also contain material relating to mining. The holdings of these “Hungarica” or Hungarian Records were created in connection with archival practices in the age of emerging nationalism in the 19th century. [4] Various files were collected that in some way had the subject “Hungary”. Noteworthy collections are: The “Montanistica”, two collections on salt and mining, as well as the collections on “Queen Maria's monetary affairs”, which hold the seven Lower Hungarian mining towns as a widows’ estates in the early period after the Battle of Mohács in 1526.

Digitized Hungarian prospecting tools

As we have seen, navigating these inventories also requires putting together pieces of a historical jigsaw puzzle. But successful early modern miners were also able to use prospecting tools to predict the location of ores? As well as the early modern miner had to reach out into landscape and find ore veins by using different prospecting tools, the historian needs such tools to find his/her precious documents in archival landscapes. To conclude, I will introduce some of the extant tools for historical prospecting, provided by the digital platform “Hungaricana” [5], which aims to make accessible Hungary´s cultural heritage digitally.

Because some inventories in the archives are still organised in early modern logics, the historian needs to understand the finding aids of the early modern archivists. Luckily, some of them are stored in the States Archive and “Hungaricana” digitized these Indices and “Protokollbücher” of the “Austrian Court Finance”. These contain references to documents in form of registers that found their way to the Court Chamber (Expedit) and that were sent out from Vienna (Registratur). All the provincial departments are united in these record books. If the researcher finds an interesting entry s/he only has to translate it into the provincial chambers and can now search for the representing document by date.

Additionally, a huge number of documents in the “Ungarisches Münz- und Bergwesen” as well as the “Niederösterreichische Hofkammer” have been catalogued in depth and provided with a Hungarian register. Here, too, you will find assistance in the prospecting of valuable archival material. Even though the “Hungaricana” provide a lot of help, there is still a huge amount of work to do for mining historians in the Habsburg archives. But isn´t this the challenge we´re searching for, as miners searching for precious metals? And therefore, I end with the traditional miners’ greeting: Glück auf! (Good luck!)
