Step-by-step explanation:
In the 1920s, Marcus Garvey and W.E.B. Du Bois agreed that Africans and people who descended from Africa should organize and work together. Both leaders believed in the importance of unity among African people and the need to fight for their rights and equality. Garvey's Improvement Association aimed to unite African descendants, while Du Bois emphasized educating African Americans to become leaders and promote social equality.
In addition to this, Garvey advocated for Pan-Africanism and a back-to-Africa movement through his Universal Negro Improvement Association, while Du Bois emphasized civil rights and integration.
