Omar Blondin Diop (1946-1973) was a West-African anti-imperialist philosopher, artist, and revolutionary from Senegal and Mali. A figure of the May 68 uprising in France and underground opposition to Léopold Sédar Senghor in Senegal in the early 1970s, he was imprisoned for planning the freeing of detained comrades who had attempted an attack on French president Georges Pompidou while on a visit to Dakar. His death in custody in May 1973 caused national and international outrage, and played a role in the establishment of a multi-party system in Senegal as of the mid-1970s. ()
