The emergence of factor markets during the transition from the middle ages into the early modern period was of crucial importance for long-term economic development. The current historiographical debate however, lacks a quantitative analysis of the market for land in the (Southern) Low Countries, one of the most densely urbanized regions with a rural economy that, by all means, can be considered pre-capitalistic. This paper focuses on two methodological issues. First, I problematize the concept of property rights and its (mis)use in historical discourse. Rather than using the property rights as a conceptual basis, I propose usage rights, since this terminology is a far better fit for the economic and social reality of the Early Modern Low Countries. Second, I elaborate on the wide variety of sources that are available to historians to study the pre-modern land market. Combining the two elements, I subsequently embed the peasant land market within its larger socio- economic context
