Abstract

If transnational activism has been studied in previous research, since the demonstration in Seattle in November 1999 a new global movement became more and more visible at the global level. One important task that a transnational social movement like this has to perform is the building up of a collective identity shared by different individuals and organisations spread around the world. By analysing documents and data from questionnaires distributed to activists during the first European Social Forum of Florence, the article tries to underline that this goal has been achieved by the construction of a master-frame, which culturally integrated different movement families and resonated with activists'ideals and values. The meaning of this master frame seems to reflect the need for a reconstruction of the different values which divided the Left in the previous decades.
