The aim of the project is – quite generally – a socio-cultural analysis of the composition (synthesis) of the society of the Byzantine Empire of the middle period (7th-11th centuries) focused on selected thematic priorities, which is essentially based on the data material compiled within the framework of the "Prosopography of the Middle Byzantine Period (641–1025 AD)" (PmbZ), but also takes into account more recent prosopographical findings. The focus of this analysis is – in particular – on a more detailed investigation and interpretation of certain social groups and their structures, i.e. both their internal hierarchization and their social localization, as well as their networks, i.e. their internal links and interactions, their connections with each other and in relation to the total population, with special consideration of modern social science methods

With regard to the various social groups to be examined, different theories and models of the social sciences are applied. Within the broader research field of Gender Studies, questions of elite sociology are of particular relevance with regard to women and eunuchs. For example, the primary question should be whether these social groups formed their own or a common elite or were merely part of an overall social elite. Questions of social network analysis are also important here. The focus should be on whether there were separate social networks of women and eunuchs, or whether the representatives of these social groups acted more in isolation. With regard to clerics and lay people, the questions of social network analysis then become even more important. The social networks and hierarchies within these social groups should be investigated and the commonalities and differences of the respective networks should be worked out. It should also be examined more closely what relationships exist between the two types of networks and what interconnections between or transformations and integrations of both networks are possible. With regard to the ethnic groups and Gentes, i.e. the still tangible indigenous peoples of Asia Minor, the islands and other regions of the empire, questions of social identity theory are particularly applied. For example, it should be examined what significance the ethnic-cultural identity of these social groups had and how it related to postulated superordinate identities, such as a Roman-Byzantine or a Christian identity. The focus on youth and old age is less suitable for the application of social science theories and models, but requires a greater inclusion of archaeological research and its results, in particular grave archaeology and age determination in skeletal examinations, and then enables a comparison of these findings from the examined Byzantine necropolises with the information from the historical sources in order to arrive at more precise and better-founded statements about the life expectancy of the Byzantines or certain social groups of the Byzantine population and about the entire age structure of Byzantine society. The project is therefore a focused and priority-oriented socio-cultural analysis on the basis of quantitative and qualitative relations of certain selected social groups of Byzantine society in the Middle Byzantine period.
