The question of who qualifies for sovereignty, and how much, went on to bedevil efforts to institutionalize the international order throughout the 20th century. The Versailles Conference, for example, made it clear that some were entitled to benefit from President Woodrow Wilson’s principles of self-determination and some were not. Eastern Europeans qualified, and the Poles, Hungarians, and others all emerged from the conference with their own states. Non-European subjects of the victorious powers, however, did not qualify, and the Egyptians and Vietnamese who showed up at Versailles to press their claims left emptyhanded. Indeed, the League of Nations mandate system codified the relationship between civilizational status and sovereignty: “Advanced nations” were formally entrusted to rule over those deemed unable “to stand by themselves under the strenuous conditions of the modern world.”
