In 1921, Davis rose in rank to become the fourth assistant President-General of the UNIA-ACL. She established UNIA-ACL divisions in Cuba, Guadeloupe, St. Thomas, Virgin Islands; Port-au-Prince, Haiti; Trinidad and Tobago, and Jamaica. Unseated by Garvey in June 1923 in an effort to quell dissent in the UNIA's New York headquarters, she was reelected during the August 1924 convention. On August 25, 1924, Davis chaired the annual convention as the Fourth-Assistant President General of the UNIA. In December, she traveled to Liberia, West Africa, as the only woman in the UNIA delegation, which was seeking consent to establish a UNIA-ACL colony in Liberia. In that same year she was a member of a committee that delivered petitions to U.S. President Calvin Coolidge seeking Garvey's exoneration on mail fraud charges. In 1925, she organized a trip through the Caribbean, taking with her Maymie de Mena as translator.
