Black Nationalist Marcus Garvey recognized that his Universal Negro Improvement Association (UNIA) would find its most enthusiastic audience in the United States, despite the organization’s professed worldwide mission. After fighting World War I, ostensibly to defend democracy and self-determination, thousands of African-American soldiers returned home to find intensified discrimination, segregation, racial violence, and hostile relations with white Americans. Sensing growing frustration, Garvey used his considerable charisma to attract thousands of disillusioned black working-class and lower middle-class followers and became the most popular black leader in America in the early 1920s. The UNIA, committed to notions of racial purity and separatism, insisted that salvation for African Americans meant building an autonomous, black-led nation in Africa. To this end, the movement offered in its “Back to Africa” campaign a powerful message of black pride and economic self-sufficiency. In Garvey’s 1921 speech, “If You Believe the Negro Has a Soul,” he emphasized the inevitability of racial antagonism and the hopelessness of interracial coexistence.
