Book excerpt: This book examines the transformation and the dynamic reconfiguration of borders within Korea through inter/trans-disciplinary approaches. The book offers a comprehensive synthesis for the changing geo-political, cultural, and economic dynamics among Korea’s diasporas by applying the theme of “diasporas within homeland” as a theoretical lens. While diaspora remains a central theoretical perspective (often highlighting “out of home” experiences), the volume turns its gaze inward, “within homeland,” to trace internal displacement, mobility, and diversity in Korea. In addition, this volume brings diverse scholarly traditions that bridge the diaspora with a wide range of theoretical lenses and methodological approaches, such as intercultural sensitivity and adaptation, acculturation, ideology critique, alienation, national memory, and postcolonialism. The book further explores the possibilities of coalition-building between/among diverse communities. As a study of the notion of Korean identity and citizenship, this book will be of huge interest to students and scholars of Korean society and culture, Asian diasporas, cultural anthropology, and ethnicity.
