The Harlem Renaissance was a cultural, social, and artistic movement that took place in Harlem, New York in the 1920s. It involved a flowering of African American literature, art, music, and social thought. Key figures included Langston Hughes, Zora Neale Hurston, and Duke Ellington. The movement arose from the Great Migration of African Americans to northern cities like New York and the development of Harlem as the center of African American cultural life.
