The Rising Tide of Color: The Threat Against White World-Supremacy (1920), later republished in other titles, like The Rising Tide of Color Against White World-Supremacy, is a book about geopolitics and racial theory by Lothrop Stoddard which predicts the collapse of white world empire and colonialism because of the population growth among people not of the white race, rising nationalism in colonized nations, and industrialization in China and Japan. Stoddard advocates restricting non-white migration into white nations, restricting Asian migration to Africa and Latin America and slowly giving Middle Eastern and Asian colonies independence. A noted eugenicist, Stoddard supports a separation of the "primary races" of the world and warns against miscegenation.
