“Uplift meetings” refers to an African American social movement in the early 1900s that sought to “lift up” black Americans in society. The movement was sparked by W. E. B. Du Bois and his book,
The Souls of Black Folk, in which he asks black Americans: “How does it feel to be a problem?” The movement addressed the civil rights of black Americans, and Florence obviously supports it. Du Bois as well as Booker T. Washington would have been among the “prominent Negroes” Florence listened to.
