Amilcar Lopes da Costa Cabral (Portuguese: [a'milkar 'lopiS ka'bral]; (1924-09-12)12 September 1924 - (1973-01-20)20 January 1973) was a Bissau-Guinean and Cape Verdean agricultural engineer, intellectual, poet, theoretician, revolutionary, political organizer, nationalist and diplomat. He was one of Africa's foremost anti-colonial leaders.
Death
In 1972, Cabral began to form a People's Assembly in preparation for the independence of Guinea-Bissau, but disgruntled former PAIGC rival Inocencio Kani, together with another member of PAIGC, shot and killed him on the 20th January 1973 in Conakry, Guinea. The possible plan was to arrest Cabral (possibly to judge him summarily, later), but facing the peaceful resistance of Cabral, they immediately killed him.  According to some theories, Portuguese PIDE agents, whose alleged plan eventually went awry, wanted to influence Cabral`s rivals through agents operating within the PAIGC, in hope of arresting Cabral and placing him under the custody of Portuguese authorities. Another theory claims that Ahmed Sekou Toure, jealous of Cabral's greater international prestige, among other motives, orchestrated the conspiracy; both theories remain unproven and controversial.  After the assassination, About one hundred officers and guerrilla soldiers of the PAIGC, accused of involvement in the conspiracy that resulted in the murder of Amilcar Cabral and the attempt to seize power in the movement, were summarily executed. His half-brother, Luis Cabral, became the leader of the Guinea-Bissau branch of the party and would eventually become President of Guinea-Bissau.  A declassified United States Department of State brief notes that the motives of his assassination are unclear but may have linked to "a feud between mulattos from the [sic] Cape Verde islands and mainland Africans." Cabral was assassinated prior to the independence of the Portuguese colonies in Africa, and therefore died before he could see his homelands of Cabo Verde and Guinea Bissau gain independence from Portugal.
