Abstract
Recently the studies of social movements have been concerned with the relation between movemnts and culture. In this paper, I utilize additional elements in the description of movements which take heed of two principles of communication operating in collective actions. The first is “Breaking away” which constructs a distinctive space playing a key role in establishing activist subcultures. The second principle is “Infiltration” by which activists spread their ideology to attract widespread support. In a case study, I describe the history of an informal network and the conflict process in which the network takes a leading role.
