Abstract:In the 19th century, the Spanish government, led by a liberal political project, put up for sale the common properties of villages, and deprived local village authorities of their capacities, powers and laws to manage common woodlands, which were passed to the Forestry Service. This paper, based on Ostrom's hypothesis that state intervention can have negative consequences for the conservation of common resources, is a case study of what happened in the province of León. It is shown that, although the conservation of common resources was endangered because those who were more directly concerned with protecting them were deprived of the means to do so, peasant communities staunchly defended the commons by maintaining traditional practices and uses in their commons.
