Amílcar Lopes da Costa Cabral (1924-1973) was a Guinea-Bissauan agronomic engineer, writer, Marxist and nationalist guerrilla and politician. Also known by his nom de guerre Abel Djassi, Cabral led African nationalist movements in Guinea-Bissau and the Cape Verde Islands and led Guinea-Bissau's independence movement. He was assassinated in 1973, just months before Guinea-Bissau declared unilateral independence.
