This article examines local credit markets and debt networks in Austria during the eighteenth century. Since professional financial institutions were inaccessible to the wider population, orphans who had inherited were a source of credit alongside kin or local institutions. Reasons for borrowing included investments, taxes or deferred payments. Events in the life-course, such as marriage and inheritance, could trigger debt relations, which were thus closely intertwined with other social relations and structured by legal practice. Guardians were appointed to administer the inheritance of children who had lost one or both of their parents, to invest it profitably and to prevent misuse by their (step-)parents or local authorities. They were often relatives or local dignitaries whose personal networks were crucial in allocating capital, and wealthy orphans could extend credit to a large number of people. Using a sample of mortgage deeds and guardianship accounts, we examine the practices of guardianship and local credit, such as the reasons for lending and borrowing, the investment strategies of guardians and the conditions and securitization of credit within and outside kinship and in varying familial constellations. In addition, we look at the position of different groups within local credit networks using social network analysis.
