The analysis of the cooperative mechanisms deployed by the socio-economic elite of the Crown of Aragon is brought to the foreground with special emphasis on human capital strategies, such as those reflected in the recruitment of commercial agents. We discuss a number of examples drawn from notarial records, account books and commercial correspondence in order to bring to light not only commercial relationships but also kinship and friendship ties.2020http://zaguan.unizar.es/record/12936010.7410/1444http://zaguan.unizar.es/record/129360oai:zaguan.unizar.es:129360RiMe – Rivista dell’Istituto di Storia dell’Europa Mediterranea 7, 3 (2020), 111-153by-nchttp://creativecommons.org/licenses/by-nc/3.0/es/info:eu-repo/semantics/openAccess
