Vietnam's current administrative reforms are drawing attention in continents, often compared with reform initiatives in some other countries. Yet such views overlook the country's long-standing tradition of reform. Over more than a millennium, Vietnam's political, economic, and social systems have undergone profound transformations initiated by diverse authorities, from early autonomous regimes and feudal dynasties to the colonial period and the modern era. These reforms have unfolded through major historical ruptures and adaptive processes. This enduring trajectory calls for a deeper historical perspective. The volume offers one of the first comprehensive overviews of more than 1,000 years of reform in Vietnam.
