The House of European History (HEH, 2017) emerges as potential aggregator of people, while aspiring to represent different communities in transnational categories, through the knowledge of a multiple but often diffuse whole. The first temporary exhibition seeks to cultivate the knowledge of the other. In the encounter that Interactions proposes, a discourse on Trading, Fighting, Negotiating and Learning is made to understand and debate how our identity is shaped. In the light of a fragmented European community and having in mind the European policy of Europeanisation through cultural heritage, it is our aim to question what narrative of the history of a continent? Which territories of exclusion or (in) visibility can we delimit? How does the HEH participate in a broader cultural policy of Europeanisation of historical memory? And, by mapping the installation and museological content of Interactions: how can a museum contribute to the debate on the meaning of “being European”?
