Like many countries around the world, Chile is undergoing a political moment when the nature of democracy and its political and legal institutions are being challenged. Senior Chilean legal scholar and constitutional historian Pablo Ruiz-Tagle provides an historical analysis of constitutional change and democratic crisis in the present context focused on Chilean constitutionalism. He offers a comparative analysis of the organization and function of government, the structure of rights and the main political agents that participated in each stage of Chilean constitutional history. Chile is a powerful case study of a Latin American country that has gone through several threats to its democracy, but that has once again followed a moderate path to rebuild its constitutional republican tradition. Not only the first comprehensive study of Chilean constitutional history in the English language from the nineteenth-century to the present day, this book is also a powerful defence of democratic values.
