This book investigates why Chile suddenly confronted a violent social revolt in October 2019, after almost thirty years of political stability, during which time the country was broadly regarded as Latin America’s most successful nation.Since democratic restoration in 1990, Chile’s relatively high levels of political stability, increasing prosperity and social modernisation have stood out in a region shaken by political convulsion and economic malaise. In early October 2019, President Sebastian Pinera confidently claimed that Chile represented a true ‘oasis’ of political stability and economic vitality in Latin America. However, just weeks later, the announcement of a small increase in the price of Santiago’s underground transport system unleashed an unprecedented wave of violent anti-government protests in the country, with protestors ultimately demanding Pinera’s resignation and the end of neoliberalism and the 1980 Constitution, among many other demands. This book analyses the causes of Chile’s socio-political upheaval, arguing that the fast social and economic modernisation produced by the neoliberal system led to a series of destabilising socio-political processes in the country.At a time when much analysis of the October uprising tends to be superficial or polarised on ideological grounds, this book provides a much-needed sociological and institutional analysis of the crisis. It will be an important read for scholars of Latin American politics and development, as well as those with a broader interest in state legitimacy, social movements and political contestation against neoliberalism.
