restricting Harrison's activities, including preventing his own branch from having him as a speaker. Harrison concluded that Socialist Party leaders, like organized labor, put the white "Race first and class after." After writing a note to the NYC executive committee telling it to "go chase itself", he was suspended from the Party for three months: he resigned from the Socialist Party in 1918, before his suspension was over, but was periodically referred to as a socialist by others for years afterwards. After resigning from the Socialist Party, Harrison increased his activism within the 1920s Single-Tax movement. Race radicalism and the New Negro Movement In 1914–15, after withdrawing from the Socialist Party, Harrison began work with freethinkers, the freethought/anarchist-influenced Modern School Movement (started by the martyred Spanish anarchist/educator Francisco Ferrer), and his own Radical Forum. He also spoke widely on topics such as birth control, evolution, literature, nonbelief, and the racial aspects of World War I. His outdoor talks and free speech efforts were instrumental in developing a Harlem tradition of militant street corner oratory. He paved the way for those who followed, including A. Philip Randolph, Marcus Garvey, Richard B. Moore, and (later) Malcolm X. In 1915–16, after a New York Age editorial by James Weldon Johnson praised his street lectures, Harrison decided to concentrate his work in Harlem's Black community. He wrote reviews on the developing Black Theatre and the pioneering Lafayette Players of the Lafayette Theatre (Harlem). He emphasized how the "Negro Theater" helped express the psychology of the "Negro" and how it called attention to color consciousness within the African-American community. In response to the "white first" attitude of the organized labor movement and the Socialists, Harrison provided a "race first" political perspective. He founded the "New Negro Movement," as a race-conscious, internationalist, mass-based, radical movement for equality, justice, opportunity, and economic power. This "New Negro" movement laid the basis for the Garvey movement. It encouraged mass interest in literature and the arts, and paved the way for publication of Alain Locke's well-known The New Negro eight years later. Harrison's mass-based political movement was noticeably different from the more middle-class and apolitical movement associated with Locke. In 1917, African Americans and others were asked to 'Make the World Safe for Democracy" by fighting during World War I. In the United States, lynchings, racial segregation and discrimination continued. Harrison founded the Liberty League and the Voice: A Newspaper
