The paper is an attempt to identify the issues meant to facilitate and intensify the intercultural dialogue, appreciated by the author as being the most fruitful way to build both a world and an intercultural cohabitation. The final result of such ample, sinuous and difficult process is, in the author’s conscience, a social and cultural space that he calls a common space of active cohabitation. The author’s hypothesis is that what we call the “socio-cultural identity” of the Romanian nation (as a part of the European and universal diversity) can only be the result of the life and activity of all the participants to the act of living together; the author endeavours (wants) to convince the others that the Rroma people also had a valuable contribution to this act. The lack of documents and other reliable sources determines the author to go to the collective memory or other sources, from which he deduces ideas and induces assertions that make this paper a debatable, even disputable one, in fact, a serious invitation to deeper researches, studies, investigations and common reflections, without prejudice. Their outcome would be the objective way towards truth and profound knowledge, without false amiabilities.
