Against the background of global and Eurozone financial crises, as well as the austerity sweeping across Europe, the pressure for governments to privatize public services is immense. Efforts to combat this are ever more necessary. This article examines one such effort, the Italian Water Movements Forum (also called just "the Forum"), a broad alliance of trade unions, social movements, development NGOs and environmental groups, and its successful 2011 mobilization supporting a referendum against water privatization. The article seeks to answer two questions. First, how was the Forum able to bring together such a wide range of different groups into a successful campaign? Second, why, despite the overwhelming success in the referendum, was there only a partial implementation of the results?
