Final answer:
The diffusion of Black culture during the Great Migration led to the Harlem Renaissance, playing a crucial role in the emergence and cultural influence of African American artists in US society.
Step-by-step explanation:
The emergence of prominent African American artists and their influential roles in US society had its roots in the diffusion of Black culture during the Great Migration. This migratory movement saw a vast shift of African Americans from the South to northern and western cities. Harlem, New York City, became a focal point for this cultural explosion, giving rise to what is known as the Harlem Renaissance. The movement saw the development of a rich cultural tapestry that included music, literature, and art. These artistic expressions not only fuelled racial pride but also greatly impacted the broader American cultural landscape. The Great Migration and the Harlem Renaissance helped establish a new space for African Americans in public life, both culturally and politically, creating opportunities for increased political activism and cultural engagement.
