The Harlem Renaissance occurred between 1920-1934 as 2 million African Americans migrated north from the rural South to cities like New York and Chicago. Cheap housing led to a boom of black homeowners in Harlem, which became a cultural epicenter. Artists explored black identity, nationalism, and social injustice through literature, poetry, music, theater and art. Key figures included James Weldon Johnson, W.E.B. Du Bois, and Langston Hughes.
