In the 1920s, Harlem in New York City became the cultural capital for African Americans. Due to racial segregation and discrimination, Harlem became a predominantly black neighborhood where around 152,000 African Americans lived by 1920. During this period, Harlem experienced a cultural renaissance and was a center of intellectual, artistic, and social activity for African Americans. Jazz music emerged from Harlem and became an influential American art form that was also divisive due to its modern and explicit nature. Debates emerged within the African American community about issues like education, cultural identity, and how to address the legacy of slavery.
