Where did yellow race shall rule the world come from?

The phrase "the yellow race shall rule the world" originates from early 20th-century racial theories and ideologies, particularly those associated with white supremacy and nationalism. It was popularized in part by the 1905 novel "The Rising Tide of Color Against White World-Supremacy" by Lothrop Stoddard, which discussed perceived threats from non-white populations. This concept reflects the anxieties and prejudices of the time, particularly in the context of Imperialism and global power dynamics. Such ideas have since been discredited and condemned for promoting racism and xenophobia.
