This paper is about social change in underdeveloped areas. It is based on field work in the European Mediterranean between 1965 and 1967. Hansen worked in the wine and champagne district of Villafranca del Panadés, roughly 30 miles from Barcelona, in Catalonia. The Schneiders were in the wheat and pastoral latifundium zone of Western Sicily. The two regions exhibit quite different patterns of land use and tenure, social stratification and settlement. We were struck, however, by two characteristics which they shared. First, we found a plethora of noncorporate social structures (for the most part coalitions) which organized fundamental economic and political activities of a quite modern sort. In rural Catalonia, coalitions of businessmen, skilled workers and government functionaries are formed within the context of an emergent bar culture, centered in major towns like Villafranca. In Western Sicily, until quite recently, the locus of similar coalitions was the latifundium. As yet, no clearly defined urban tradition has replaced this predominantly rural one
