Du Bois vs. Garvey: Public Debates and Organizing in Harlem (1919–1926)

1. Postwar Harlem becomes a mass organizing hub

   Jan 1, 1919Labels: Harlem, UNIA

   In 1919, Harlem was a center for Black political debate and institution-building after World War I and the Red Summer of racial violence. Marcus Garvey’s Universal Negro Improvement Association (UNIA) was already headquartered in Harlem, with offices and meeting spaces that could draw large crowds. This set the stage for public clashes over strategy: integration and civil-rights litigation versus separatism and global Black nationhood.

2. Du Bois convenes the First Pan-African Congress

   Feb 19, 1919Labels: W E, Pan-African Congress

   W. E. B. Du Bois helped organize the First Pan-African Congress in Paris in February 1919 to press for reforms in African colonies after World War I. The meeting reflected Du Bois’s approach: lobbying, international petitions, and building alliances among educated Black leaders and sympathetic officials. These Pan-African efforts overlapped with, but differed from, Garvey’s UNIA mass movement in Harlem.

3. Garvey launches Black Star Line fundraising drive

   Jun 27, 1919Labels: Black Star, UNIA

   Garvey and UNIA leaders incorporated the Black Star Line in June 1919 as a Black-owned shipping venture meant to support trade and the larger "Back to Africa" vision. The company quickly became a symbol of economic self-reliance, raising money through small stock purchases by supporters. It also created a major point of criticism from rivals when the business struggled.

4. UNIA dedicates Liberty Hall as organizing headquarters

   In July 1919, the UNIA dedicated Liberty Hall in Harlem, which became the central stage for weekly mass meetings, speeches, fundraising, and organizing. The space helped Garvey turn political ideas into visible, disciplined public mobilization through parades, uniforms, and large conventions. Liberty Hall also became a focal point for critics who argued that Garvey’s spectacle masked weak finances and unrealistic promises.

5. Bureau of Investigation assigns agent to infiltrate UNIA

   Nov 19, 1919Labels: Bureau of, James Wormley

   As Garvey’s influence grew, the U.S. Bureau of Investigation increased surveillance of the UNIA. In November 1919, James Wormley Jones was appointed as the Bureau’s first Black special agent and was assigned to infiltrate Garvey’s organization. This marked an escalation in federal monitoring that later fed into legal pressure on Garvey and his businesses.

6. UNIA convention adopts Declaration of Rights

   Aug 13, 1920Labels: UNIA, Declaration of

   During the UNIA’s first international convention in New York in August 1920, delegates adopted the "Declaration of Rights of the Negro Peoples of the World." The declaration asserted global claims to dignity, protection, and political rights, and it helped popularize UNIA’s international vision. This month-long convention demonstrated Garvey’s ability to organize a mass movement that competed with older civil-rights organizations for leadership and legitimacy.

7. Du Bois and Garvey rivalry sharpens in print

   Jan 1, 1921Labels: W E, Marcus Garvey

   By the early 1920s, Du Bois (as editor of The Crisis, the NAACP magazine) and Garvey publicly criticized each other’s aims and methods. Du Bois argued that Garvey’s leadership and business claims were dangerous, while Garvey attacked the NAACP and Du Bois as too willing to seek approval from white power structures. The conflict became part of Harlem’s broader argument over whether progress would come through integrationist civil-rights campaigns or separatist Black-nationalist organizing.

8. Second Pan-African Congress meets across Europe

   Aug 28, 1921Labels: Pan-African Congress, W E

   In late August and early September 1921, the Second Pan-African Congress met in London, Brussels, and Paris, again with Du Bois in a leading role. The sessions focused on racism, colonial rule, and paths toward African self-government, emphasizing petitions and diplomacy. The Congress highlighted a strategic split: Du Bois pursued international advocacy through elite networks, while Garvey built a mass movement centered in Harlem and the African diaspora.

9. Garvey arrested on Black Star Line mail-fraud charge

   Jan 1, 1922Labels: Marcus Garvey, Black Star

   In January 1922, Garvey was arrested and charged with mail fraud connected to Black Star Line stock sales and promotional materials. The arrest intensified Harlem’s factional conflict, as Garvey blamed rival Black organizations and enemies for a political conspiracy, while critics argued the case showed irresponsible leadership. After the arrest, Garvey suspended Black Star Line activities, weakening a key pillar of UNIA’s economic program.

10. Garvey trial begins under Judge Julian Mack

    May 18, 1923Labels: Marcus Garvey, Federal trial

    Garvey’s federal mail-fraud trial began in New York on May 18, 1923, and became a major public event. The proceedings reflected not just legal questions about business practices, but also political pressure around a movement that had mobilized hundreds of thousands of followers. Garvey ultimately represented himself for part of the case, which affected how the trial unfolded.

11. Jury convicts Garvey of mail fraud

    Jun 18, 1923Labels: Marcus Garvey, Jury verdict

    On June 18, 1923, a jury found Garvey guilty of a scheme to defraud, while his co-defendants were acquitted. The conviction damaged Garvey’s public standing and gave opponents new material to argue that his movement mixed real racial pride with risky promises. It also deepened the ongoing conflict with Du Bois and the NAACP, who had treated Garvey as a dangerous rival for years.

12. Du Bois escalates attacks in "A Lunatic or a Traitor"

    May 1, 1924Labels: W E, The Crisis

    In May 1924, Du Bois published a forceful Crisis editorial titled "A Lunatic or a Traitor," arguing that Garvey had harmed Black political progress. The piece framed Garvey not as a misguided ally but as a major threat to Black people in the U.S. and globally. This public condemnation shows how the Harlem debate over leadership had hardened into personal and organizational warfare.

13. Garvey begins prison term at Atlanta penitentiary

    Feb 8, 1925Labels: Marcus Garvey, Atlanta Penitentiary

    After appeals and delays, Garvey began serving his sentence in federal prison in early February 1925. His incarceration removed UNIA’s most visible leader from Harlem at a moment when the organization was already strained by financial setbacks and internal conflict. The power vacuum contributed to factional disputes and weakened UNIA’s ability to project unity.

14. UNIA loses Harlem offices amid tax and legal pressures

    Jan 1, 1926Labels: UNIA, Harlem office

    By January 1926, the UNIA lost its major West 135th Street office space when the building was sold to pay back taxes, and additional UNIA properties were sold later in 1926. These losses signaled a concrete decline in the organization’s Harlem infrastructure during Garvey’s imprisonment. The shrinking physical presence in Harlem marked an end point for the 1919–1926 phase of intense Du Bois–Garvey rivalry centered on public debate and mass organizing in the neighborhood.
