The Centro de História d’Aquém e d’Além-Mar (CHAM) is an R&D institution working in an interuniversitary basis. Localized in the Faculty of Social and Human Sciences – New University of Lisbon (FCSH-UNL) it is strictly connected with the Azores University (UAc) and is financed by Portuguese Foundation for Science and Technology  (FCT).

CHAM develops research related to the History of the Discoveries and the Portuguese Expansion, as well as the Portuguese presence around the world, with a special focus in the period between the origins of the Overseas Expansion and the Independence of Brazil (1822), with an interdisciplinary perspective and incorporating comparative history, paying particular attention to the history of the regions with which Portugal maintained contacts.

This wider area of research has potential for the study of interculturalism, especially in terms of the otherness, perceived by the Portuguese and other European peoples, and vice-versa, during the process of European expansion. Res Antiquitatis’ main contribution to the more general scientific purposes of CHAM is the study of that interculturalism and those conceptions of the otherness in diacronic terms, more specifically starting with the cultural references of Antiquity.
