摘要：This article analyzes the origins and the evolution of the terrorist network responsible for the 11 March 2004 bombings. The article uses as its main source of information the related judiciary documents which are open to the public. Regarding this material, the research applies the social networks analysis, a method that will bring a clear and deep understanding of all the groups and interactions that pre-existed and gave life to the terrorist network. At the same time we analyze the social networks that gave origin to the structure of the group. The article also studies the intermediating role of several individuals particularly involved. Finally, the authors draw some conclusions that go beyond the case of the 11-M and that can be applied in general to the organizational structures of the Jihadist terrorism.
