A biography of Prince Phetsarath highlights how a specific idea about Laos and its culture was formed under French colonial rule and nurtured under the Japanese occupation and its aftermath. During these periods, Phetsarath's understanding of Lao cultural nationalism was transformed into a political and anticolonial nationalism. While ultimately a study of failure, Phetsarath's activities show that anticolonial nationalism did not always have to be linked to Communist movements to be ‘revolutionary’, and suggests the importance of taking into account non-revolutionary and non-Communist actors – even members of royal blood – in order to better understand the complexity that went into the making of modern postcolonial states.
