This article reviews recent scholarship on the urban politics of mega-events. Mega-events have long been promoted as drivers of urban development, based on their potential to generate beneficial legacies for host cities. Yet the mega-event industry is increasingly struggling to find cities willing to host. Political arguments that promote mega-events to host cities include narratives about mega-event legacy—the potential for events to generate long-term benefits—and mega-event leveraging—the idea that cities can strategically link event planning to other policy agendas. In contrast, the apparent decline in interest among potential host cities stems from two political shifts: skepticism toward the promises made by boosters, and the emergence of new kinds of protest movements. The article analyzes an example of largely successful opposition to mega-events, and evaluates parallels between the politics of mega-events and those of other urban megaprojects.
