The three chapters of Part I present an overview of the events of the British and French riots, draw lessons for theory from the British riots of the 1980s and 1990s, and present a historical review of French riots between 1981 and 2004. The five chapters of Part II address only the British riots that occurred between 2001 and 2005. One chapter focuses on local events and national implications for the riots in Oldham and Burnley in 2001. Another chapter examines the features of police management of inter-ethnic conflict in the Bradford riot. Other chapters address the varying motives for the behaviors of rioters, and the effectiveness of youth workers in Oldham in implementing new post-riot policies for work with youth of diverse ethnicity. Part III's seven chapters focus on the French riots from 2001 to 2008. Riot-related issues discussed include immigrant urban segregation, the role of urban renewal policies in the riots, a historical overview of immigrant mobilization in France (1968-2008), and youth gangs' role in the riots. Other chapters in Part III consider the role of the French national police in the urban riots and how the residents of riot areas voted in the 2007 presidential election. The chapters of Part IV consider the Cincinnati riot and its aftermath in 2001 in the United States, as well as police-minority youth interactions in Germany that have assisted in preventing riots. 9 tables, 10 figures, and 378 references
