My initial questions are significantly contextualized by: (1) the metropolitanconfiguration; (2) the transition to democracy; and (3) the Europeanization of localpolicies. What I am interested in here is determining how citizen participation hasdeveloped in the field of urban planning within the framework of those three politicalconditioning factors and a unique set of urban movements. This participation is, in myopinion, one of the key aspects of the interaction of urban movements with localgovernments in recent decades. In fact, a surprising and stimulating factor in my researchhas been to observe that these interactions have evolved in very different ways from verysimilar origins
