Volume XIII of The Marcus Garvey and Universal Negro Improvement Association Papers covers the twelve months between the UNIA's second international convention in New York in August 1921 and the third convention in August 1922. It was a particularly tumultuous time for Garvey and the UNIA: Garvey’s relationship with the UNIA's top leadership began to fracture, the U.S. federal government charged Garvey with mail fraud, and his Black Star Line operation suffered massive financial losses. This period also witnessed a marked shift in Garvey's rhetoric and stance, as he retreated from his previously radical anticolonial positions, sought to court European governments as well as the leadership of the Ku Klux Klan, and moved against his political rivals. Despite these difficult and uncertain times, Garveyism expanded its reach throughout the Caribbean archipelago, which, as Volume XIII confirms, became the UNIA's de facto home in the early 1920s. The volume's numerous reports from the UNIA's Caribbean divisions and chapters describe what it was like for UNIA activists living and working under extremely repressive circumstances. The volume's major highlight covers the U.S. military's crackdown on the UNIA in the Dominican Republic, as documented in the correspondence between John Sydney de Bourg—whom Garvey had dispatched to monitor the situation—and U.S. and British government officials. In addition to UNIA divisional reports and de Bourg's extensive correspondence, Volume XIII contains a wealth of newspaper articles, political tracts, official documents, and other sources that outline the complex responses to Garveyism throughout the United States, the Caribbean, and Europe, all the while documenting this watershed moment for Garvey and the UNIA.

Volume XII of the "Marcus Garvey and Universal Negro Improvement Association Papers" covers a period of twelve months, from the opening of the UNIA's historic first international convention in New York, in August 1920, to Marcus Garvey's return to the U.S. in July 1921 after an extended tour of Cuba, Jamaica, Panama, Costa Rica, and Belize. In many ways the 1920 convention marked the high-point of the Garvey movement in the United States, while Garvey's tour of the Caribbean, in the winter and spring of 1921, registered the greatest outpouring of popular support for the UNIA in its history. The period covered in the present volume was the moment of the movement's political apotheosis, but also the moment when the finances of Garvey's Black Star Line went into free -fall.
Volume XII highlights the centrality of Caribbean people not only to the convention, but also to the movement. The reports to the convention discussed the range of social and economic conditions obtaining in the Caribbean, particularly their impact on racial conditions. The quality of the discussions and debates were impressive. Contained in these reports are some of the earliest and most clearly enunciated statements in defense of social and political freedom in the Caribbean. These documents form an underappreciated and still underutilized record of the political awakening of Caribbean people of African descent.
