Which culture had the strongest influence on jazz dance after 1950?

After 1950, the culture that had the strongest influence on jazz dance is arguably the African American culture. The dance form, which originated in the late 19th and early 20th centuries, was significantly influenced by African dance traditions, and this influence continued to evolve post-1950. African American music, especially jazz music, played a vital role in the development of jazz dance during this period. Choreographers like Bob Fosse, who was known for his unique style and influence on Broadway and Hollywood, drew heavily on the African American vernacular moves, blending them with his theatrical vision.

Jazz dance was also influenced by other popular music and dance trends initiated or popularized by African Americans, such as rock and roll, soul, and later on, funk and hip-hop. These elements contributed to new styles of jazz dance that emerged during the second half of the 20th century, often characterized by more relaxed, street dance-influenced movements compared to the more theatrical and structured styles seen earlier.
