My recent book, Maritime Ryukyu, 1050-1650, is a revisionist history of the Ryukyu islands. Adopting the interdisciplinary approaches of recent Japanese scholarship, Maritime Ryukyu presents a new history of the region, treating the Ryukyu islands not as a unitary, natural political community but as locations within a maritime network that extended northward as far as the southern coastal regions of Korea. This article briefly explains my trajectory in writing the book and then summarizes some of the major arguments in Maritime Ryukyu.
