What are the explaining factors for the wave of riots in France in November 2005? In providing some answers, this article begins by examining the practical usefulness of the French republican model of integration for social cohesion, highlighting the way its negation of other criteria, such as ethnicity, race, or religion, limit this national conception of citizenship and emphasizing these excluded factors as one of the main causes of frustration and resentment among migrant groups in France. The author compares these riots to the student movements in spring 2006 and shows some similarities as well as important differences between the explaining structural factors of these two youth-based social upheavals. One of the contributing distinctions is the experience of ethnic and racial discrimination as an important source of deep resentment. The author avoids reducing the riots simply to a clash between ethnic groups with specific ethnic interests or a class revolt. Instead, he stresses the relationship between specific social structural factors and spatial effects as the element that created the context for the riots by transforming inequalities into visible and indefensible discrimination. Several factors show that spatial aspects (in the form of segregation) are important alongside the ethnic/racial ones in explaining the riots. (Contains 2 figures and 27 notes.)
