This open access book provides fascinating insights into the incredible changes that Vietnam underwent in the long twentieth century as it transformed from an early modern kingdom to a European colony, to a divided land with opposing ideologies, and to a unified country in a globalized world. At each stage in this long century of changes, there were Vietnamese who sought to mold their society into some vision of “modernity.” The book looks at multiple, rather than one form of modernity, and links those forms with the different political moments that Vietnam experienced, in tandem with the outside interlocutors that were maintained during those periods. As such, this book provides a holistic view of the many forms of modernity and their global links that can be found in Vietnam over the course of the long twentieth century. These multiple modernities are documented in this book, and the authors do so by bringing together the strengths of “traditional” language-based area studies scholarship with the insights that an awareness of trans-national and global perspectives provides. Relevant to historians and researchers in the broader arena of Southeast Asian studies with a particular interest in Vietnam—its journey from past to present—this book is a must-read engagement with a country that has undergone and continues to experience, rapid transformation.
