This article aims to interpret, from the paradigm of complexity, the social movement against attempts to monopolize and privatize maize in Mexico. The hypothesis is put forward that this history of resistance is selforganized in a decentralized and rhizomatic network, in which a wide variety of heterogeneous agents are articulated, forming a multi-scale, multi-strategic and multi-territorial structure. This composition of forces constitutes a clear example of social power woven from a wide diversity of centers and perspectives, and a sample of the type of popular networks woven against the processes of accumulation by dispossession.
