In 1966, the First World Black Festival of Arts and Culture held in Dakar, Senegal honored Dr. Diop and Dr. W.E.B. DuBois as the scholars who exerted the greatest influence on African thought in twentieth century. In 1974, a milestone occurred in the English-speaking world when the African Origin of Civilization: Myth or Reality was finally published. It was also in 1974 that Diop and Theophile Obenga collectively and soundly reaffirmed the African origin of pharaonic Egyptian civilization at a UNESCO sponsored symposium in Cairo, Egypt. In 1981, Diop's last major work, Civilization or Barbarism: An Authentic Anthropology was published.
