ABSTRACT
The reigns of Afonso V, Joao II and Manuel I are important, i.e., from the perspectives of finance, credit and economic dynamics, as Portugal seeks to recover from an extremely exhausting period for the treasury. In Portugal the integration between history and economics, with regard to studies related to the Middle Ages and early modern periods, both in scientific terms and in institutional terms, is lacking a major collective, connected and coordinated effort. It is worth noting the development of the studies all over Europe, in Spanish institutes or in France, with cooperation between the various research units and departments within the Ministry of Economy of that country. Royal officers’ payments, the products that circulated within the kingdom and the wealth scattered in a double way between Portugal and its commercial outposts conquered can be analyzed through the sources, which are able to offer information of particular products, prices, quantities imported and exported, addressees and persons involved in those transactions.
