argues that the defining feature of the Age of Revolutions in Latin America was the emergence of dissent as an inescapable component of political life. While contestation and seditious ideas had always been present in the region, never before had local regimes been forced to consider radical dissension as an unavoidable dimension of politics. Focusing on urban Chile between the first anticolonial conspiracy of 1780 and the consolidation of an authoritarian regime in 1833, the book argues that this revolution was caused by how people practiced communication and framed its power.
