Book excerpt: In this historical reassessment of southern Vietnam and its distinct culture, Li Tana illuminates the resourceful qualities of the Dong Trong pioneers, develops a meticulous analysis of the Nguyen trade and taxation systems, and, in the process, redefines the chief cause of the Tay Son rebellion. Li Tana's study focuses on the socio-economics of Nguyen Cochinchina, such as: the role of foreign merchants, the region's trading economy, demographic influences, religious and cultural values, how Nguyen rule affected Vietnamese settlers, relationships with uplanders, and processes of localization and identity formation.
