Researching the Gotha collections and their contexts has been a focus of the Research Centre not only since the founding of the Gotha Collection and Research Network in 2016. In 2012-2016, for example, "Collection-related research on the publishing house Justus Perthes" was carried out at the FZG in cooperation with the Gotha Research Library and Professor Dr. Susanne Rau (Erfurt) and with the support of the Thuringian Ministry for Education, Science and Culture (since 2014 Thuringian Ministry for Economis Affairs, Science and Digital Society). In 2014-2017, in a project also funded by the TMWWDG and carried out jointly with the Gotha Research Library, the sources relevant to the history of education in the Research Library, the Thuringian State Archives - Gotha State Archives, the Friedenstein Castle Foundation, and the Gotha Municipal Archives were indexed and brought together in a digital repertory. Currently, a research project funded by the DFG is dedicated to the creation of the Chinese Cabinet at Friedenstein Castle during the reign of Duke August (1772-1822).

The focus of this research on material culture is not only on the objects themselves, but also on the contexts, practices, and organizational structures of acquisitions at the Gotha court and of other collections, as well as on the associated knowledge techniques and scholarly practices, as reflected, for example, in controversies about hair, beards, and wigs or in theAntiquarianism of the 17th and 18th centuries. Numismatics, which enjoyed high prestige in the early modern period and can virtually be considered an antiquarian "leading science," plays a central role in this context. In recent years, intensive basic research has been carried out in several projects, including a comprehensive analysis of the "Magnum ac Novum Opus" of Jacopo Strada (ca. 1515-1588), a 30-volume corpus of coin drawings in the Gotha Research Library, with regard to its historical and artistic context and its sources, as well as research into the emergence of university coin collections in the 18th century in the BMBF joint project "[NUMiD] Shaping History/Preserving Values". In the future, the rich Gotha coin holdings, the practices of their collection and cataloguing, and their embedding in different disciplinary contexts are to be researched in greater detail under the heading "Numismaticsin Context" in cooperation with the Gotha Research Library and the Friedenstein Castle Foundation. The expansion of numismatics in the context of global history also plays a role, and a first step towards this is the consolidation of the relevant holdings in a virtual coin cabinet.

From the Gotha collections, numerous references to and interconnections with non-Europe can be identified. The question of the origin of objects and the investigation of their biographies is therefore closely connected with the reconstruction of global networks of knowledge and the potentials and problems of a Global History of Ideas, which Martin Mulsow has exemplified in a monograph. This topic will be developed into a main focus of the research center starting in 2023 thanks to a specific fellowship program of the Gerda Henkel Foundation. The focus will be, on the one hand, on methodological questions and problems as well as on overcoming them through a multidisciplinary approach, and, on the other hand, on concrete case studies of the cultural translation of oriental and "Asian" materials, for example in a project within the framework of the DFG priority program"Transottomanica."

Not least with a view to these global references of the history of knowledge, the theme of the 15th working conference of the AG Frühe Neuzeit im Verband der Historiker und Historiker, which will take place in Gotha in September 2024, is "WissensWelten".
