To survive over time, a diaspora must create sites of belonging and micro places in which to concentrate the main elements of its “iconography” that can consolidate social networks. This article analyzes how second-generation Greeks in Italy fit into diaspora networks by investigating the ways in which they define their sense of Greekness and use their ethnic resources. The findings of field research show a weakness of (formal and informal) social network ties and the pre-eminence of the family’s role in the process of sociocultural identification and ethnic identity construction. In fact, the second generation’s “ways of belonging” and the sense of attachment to Greece have an autonomous significance and are expressed more at a familial level and less collectively. Familial socialization plays a mediating role in the process of identification and transmission of Greekness, as well as in guiding ways of employing ethnic resources, contributing to the maintenance of the diaspora.
