The literature on cooperatives often conceptualizes cooperativism as an organized effort to embrace community participation. Through the analysis of agrarian cooperatives in Sicily that were formally established to counter the Mafia and by ethnographically exploring the notion of community for cooperativism, this article aims to problematize this idea of cooperatives as “community economics”. It proposes an anthropological approach that critically analyzes divisions of labor and the internal factions' divergent concepts of “community”. In Sicily, workers in “anti-Mafia” co-ops recognize a sense of community and “way of life” in Mafia-influenced mobilizations outside the cooperative environment, contrary to the co-op administrators' legalistic views of community. The article illuminates how the fact that often co-op members draw on different ideas of community can lead to contradictions and tensions, especially as there are different social realities underlying those ideas.
