This article seeks to assess the way in which young Colombian male and female migrants in Spain establish links and transnational political bounds in relation to their political identifications, as well as the factors which mediate in the founding of their transnational activism. The analysis should be understood in the frame of a qualitative, ethnographical and longitudinal research. The author´s target is young Colombian population which migrated due to several reasons (family regrouping, on their own, or exile), from 2001 to 2007, in the Spanish regions of Madrid and Murcia. The political identifications of young men and women migrants are transformed according to specific social, political, cultural and economic contexts in their origin and destination countries, and to their spatial and temporal dimensions. All these factors exercise a crucially significant influence on the establishment of their transnational political participation.
