New York City's Harlem neighbourhood became the center of Black American culture in the 1920s, and another "Harlem Renaissance" has been taking place in more recent years, this one driven by immigrants from sub-Saharan Africa. The new book "Africans in Harlem: An Untold New York Story" shines light on the African cultural influence shaping the neighbourhood. Author Boukary Sawadogo, associate professor of cinema studies at the City University of New York, explains that three quarters of African arrivals to the US came after the year 2000, many of them economic migrants from French-speaking countries like Senegal, Mali and Burkina Faso. Sawadogo joined us to chat about the African affinity for Harlem, the relationship between Africans and African-Americans, and the power of seeing Black heroes on screen in films like "Wakanda Forever" and "The Woman King".
