Whether aesthetically or politically inspired, graffiti is among the oldest forms of expression in human history, one that becomes especially significant during periods of social and political upheaval. With a particular focus on the demographic, ecological, and economic crises of today, this volume provides a wide-ranging exploration of urban space and visual protest. Assembling case studies that cover topics such as gentrification in Cyprus, the convulsions of post-independence East Timor, and opposition to Donald Trump in the American capital, it reveals the diverse ways in which street artists challenge existing social orders and reimagine urban landscapes.
