Protests against proposed immigration laws arose in cities across the United States during the spring of 2006. Many of the attendees were Latino, and waved flags. At first, flags of Mexico and other Latin American countries were displayed. Following negative reactions in the media, protest organizers asked rallygoers to fly the U.S. flag alongside or instead of the flags of Latin American countries. This article traces the history of flag-flying at these immigration protests, analyzes the motives of those displaying flags, and discusses the reaction to the display of Latin American flags. The disputed meanings imputed to the use of flags by the protesters and those who objected to the use of the flags is discussed in terms of symbolic conflict.
