CARMEN. The worldwide medieval network
A worldwide network of medievalists, its name being an acronym for the “Co-operative for the Advancement of Research through a Medieval European Network”. It links a number of research institutions, universities, interest groups and individuals with common scholarly interest in the study of the Middle Ages. While based in Europe, it reaches out to all continents to create an open and truly international platform of co-operation in the field of medieval research and teaching.

FIDEM. Fédération Internationale des Instituts d’Études Medievales
Its main objectives are: to represent efficiently the member institutes and centres among national and international organizations, to support scientifically, morally and financially research in medieval studies, to organize information exchange, to further concerted action in relation to teaching programmes and major research projects, to encourage meetings between researchers and to favour exchanges of lecturers, speakers, researchers and students.

International Network Small Cities in Time (In Scit)
According to its statutes, this network “represents a collaborative platform among etween researchers, from any scientific field, and as well as all entities developing and/or promoting research on small urban communities, addressed through their historicity”. Thus, this structure aims to achieve two complementary objectives which the same document identifies as “developing scientific research on small towns, from a multidisciplinary perspective, from the origin of urban nuclei to the present day” and “promoting the joint working between researchers and local, national and supra-national bodies which currently represent small towns, thus raising the impact of research on decision-makers and society”.

Ménestrel. Médiévistes sur le net: sources, travaux et références en Ligne
Our objectives: to promote the development of European resources for the study of the Middle Ages on the Internet, and more particularly of French-speaking resources, to facilitate the visibility of the work of medievalists at the international level and to contribute to the dynamism of scholarly exchanges; to offer, free of charge, a critical repertory of resources available on the Internet in the field of medieval studies, for the use of researchers, students and informed amateurs.

NEMUS – Network for the Environment in Medieval Usages & Societies

NEMUS is chaired by the IEM researcher Tiago Viúla de Faria, co-chaired by phylogeneticist Elisabete Godinho Pires, and hosted by IEM at NOVA FCSH, with support from the Portuguese Science Agency – FCT.

RURALIA
RURALIA is an associative research network established by representatives from various countries for boosting the archaeological study of medieval settlements and rural life in Europe, which correspondingly promotes the carrying out of studies, the dissemination of the research results developed in member countries and provides associations of researchers for international projects bringing together several member countries. Catarina Tente, IEM researcher, is the vice-president of this newtwork.
