The object of this essay is to understand how the ethnic Csángó’s migratory process develops since the fall of the Romanian communist regime. To do so, we will first present an overview of the major processes that affected the Csángó’s culture, identity and way of life: the building of the Romanian nation-state and the communist modernization of Romania. Starting from a theoretical proposal based on an ecological model of migration, we expose the importance that culture and social networks of exchange have in the migratory process of this group.
