Abstract
This profile discusses the organization, goals and practices of the Spanish 15M movement. I argue that it developed as a complex, multi-layered ecosystem, mobilizing a new generation of citizens through the convergence of struggles over housing and the Free Culture and Digital Commons Movement (FCM), creating a common framework for action through social networks. Primarily in and through the actions in public squares, the 15M movement also constructed further layers of mobilization, incorporating the networks and skills of previous social movements (such as those mobilizing over inter alia education, health, alternative consumption) and connecting with previous generations who had mobilized over civil liberties in transition to democracy. Furthermore, I argue that links with the Free Culture Movement had a profound effect on the genealogy of 15M—in terms of its composition, agenda, framing and organizational logic. The methodology is based on case studies of both the FCM and 15M between December 2010 and December 2011 in Spain.
