Black science fiction or black speculative fiction is an umbrella term that covers a variety of activities within the science fiction, fantasy, and horror genres where people of the African diaspora take part or are depicted. In the late 1990s a number of cultural critics began to use the term Afrofuturism to depict a cultural and literary movement of thinkers and artists of the African diaspora who were using science, technology, and science fiction as means of exploring the black experience.
