Afro-Colombian organizations: A sociological approximation is one of the most complete studies conducted in the last years in Colombia on this field. From a socio-historical perspective, crossing race, class and ethnic categories and using Niklas Luhmann organization concept, these organizations origins, structures, repertoires, leadership and meaning frames are thoroughly analyzed. A crucial question in contemporary Colombia is whether there is a social movement of Afro-Colombian people. One of the most relevant conclusions of the book is that from the promulgation of Law 70 of 1993—although not exclusively—the afro organizational framework is structured in a wide, heterogeneous and complex universe, that differs in its "nature", objectives, organizational forms, formalization degree, leadership, scale, capacity to interpellate the state and to deploy collective actions of different order.
