When we think of Vietnamese history, we tend to think of plucky peasant guerillas fighting for their independence against French colonial rule or American imperialism - or even mighty China. In her new book, A Maritime Vietnam: From the Earliest Times to the Nineteenth Century (Cambridge UP, 2024), Li Tana challenges this powerful stereotype by recasting Vietnam as a maritime state with a long history of dynamic commercial relations with the outside world, from China, to Southeast Asia, to India, and the Middle East. The book aims to escape from the rigid nationalist historiography that has long characterized history writing on Vietnam and develop a new way of thinking about Vietnam’s history that emphasizes its outward, commercial relations. It also revisits the old question of whether we should view Vietnam as an East Asian country, oriented towards China, or a Southeast Asian country, characterized by a cosmopolitanism and historical openness to maritime trade and the outside world. This is a provocative and important book which challenges powerful ideas about the way we understand Vietnam’s history and place in the world.
