New in paperback. Hardcover was published in 2023. This book explores the legacy of the Japanese empire in Korea, asking how colonialism arose as a legal idea. What was the legal process behind the establishment of colonialism as Japan's prime strategy towards Korea since the late 19th century? By addressing such questions, it is not only possible to address how Japanese colonialism in Korea was born, but also address how the process behind the making of colonialism as a judicial and legal project was illegal from its origination. As East Asia grapples with a new generation of power politics, these sober reflects lend an important historical context to the struggles of the present.
