"Since the early 2000s, global, underground networks of insurrectionary anarchists have carried out thousands of acts of political violence. This book is an exploration of the ideas, strategies, and history of these political actors that engage in a confrontation with the oppressive powers of the state and capital. This book challenges the reader to consider the historically ignored articulations put forth by those who communicate through sometimes violent political acts-vandalism, sabotage, arson and occasional use of explosives. These small acts of violence are announced and contextualized through written communiqu's, which are posted online, translated, and circulated globally. This book offers the first contemporary history of these digitally-mediated networks, and seeks to locate this tendency within anti-state struggles from the past."
