Final answer:
The Harlem Renaissance had a positive impact on U.S. cultural identity by celebrating African-American culture and promoting racial pride.
Step-by-step explanation:
One of the positive impacts that the Harlem Renaissance had on U.S. cultural identity during the 1920s was the celebration of African-American culture. During this time, African-American artists and writers formulated an independent Black culture, rejecting any emulation of white American culture. They encouraged racial pride and highlighted the richness of African-American culture through literature, art, and music. This cultural movement instilled in African Americans a new spirit of self-determination, pride, and political activism.
