This book presents research focusing on the Vietnam Nationalist Party (Việt Nam Quốc dân đảng) from 1927 to 1954. It elaborates on the party establishment, political ideology and organizational structure, the Yen Bai Uprising, the party downfall, and its role in the Vietnamese Revolution. Findings are presented systematically and comprehensively, relying on official and unofficial, as well as domestic and foreign sources, including  texts from localities and hometowns of vital figures in the organization. The author compares, contrasts and evaluates this complex collection of documents based on the theoretical perspectives of conflict theory, social system theory, social structuralism and functionism, dialectic materialism and Marxist theory. It is essential reading for Vietnamese and international researchers interested in Vietnam political context in the early twentieth century and for undergraduate and postgraduate programs in Vietnam history and politics.
