Born between September, 1924, and July, 1925, we find ourselves in the centenary years of Amilcar Cabral, Frantz Fanon, Patrice Lumumba and Malcolm X. These four figures, all critical to the thinking of the Africana diaspora, were all born within ten months of each other. Cabral (September, 1924), is the oldest of these figures, followed by Malcolm X (May, 1925), Lumumba and Fanon (both July, 1925, just 18 days apart). "4 @ 100" celebrates the centenary of these historic African births by gathering four scholars, Yousuf al-Bulushi (Fanon), Merle Collins (Malcolm X), Kasareka Kavwahirehi (Lumumba) and Reiland Rabaka (Cabral) who each contribute a long essay. "4 at 100" renders each of these figures as philosophers of the Africana diaspora, demonstrating how their thinking has shaped, and continues to do so, the field of Africana Studies since its inception in the late-1960s. With a brief introduction by Grant Farred, each of the contributors takes up an aspect of Cabral, Fanon, Lumumba and Malcolm X's thinking, offering through their essays an incisive account of why it is that these figures continue, a century after their birth in Africa, America, and the Caribbean, to enhance the critical project that is Africana Studies.¿¿.
