What was the last style of jazz music to develop?

The last style of jazz music to develop was Afrofuturism, which is a movement that combines African American culture with futurist ideas. It emerged in the late 1990s and is still evolving. Afrofuturism draws on various musical genres, including jazz, electronic, hip-hop, and soul, and often incorporates elements of science fiction, Afrofuturism challenges traditional notions of race, identity, and history, and explores the potential for a more equitable and technologically advanced future.
