The turn of the 20th and 21st centuries marked the beginning of a new methodological approach in the humanities. Thanks to the tools of digital development, data mining is made possible on huge corpora, and the "mined" data can be networked, made part of open databases that can be accessed and modified globally. Decades of basic historical research can be done in a few months. The discipline of digital humanities may be seen by many as the foundation of a new kind of positivism and fact-based data production, a new kind of structuralism if you like, which would thus find its roots in a historical-theoretical context that would be at odds with the narrative approach. But the framework offered by digital humanities is no more than a tool, which remains fatally subordinated to the historian's approach, to his or her biases, to the resource endowments and to the uncertainties of context. As such, it is not an antithesis, but rather a companion to the developing approaches in historiography, and can therefore be just as much a facilitator of narrativist and structuralist approaches. This issue will be discussed in more detail in the methodological chapter.In my work, therefore, I intend to demonstrate that the application of digital methodology to the corpus of texts in Bethlen does not serve the mere accumulation of data series, but has a dual purpose. The Bethlen oeuvre consists of numerous letters, pamphlets, several memoirs, pamphlets and documents, so that both quantity and variance are important.
