The Harlem Renaissance was a cultural movement in the early 20th century where African American art, music, dance, and literature flourished. It originated in Harlem, New York in the 1920s as many African Americans migrated north during the Great Migration after World War 1. Notable writers included Langston Hughes and Zora Neale Hurston, while jazz musicians like Louis Armstrong and Duke Ellington gained popularity. The movement declined during the Great Depression as supporting organizations faced economic pressures.
