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.

From 1963 to his assassination in 1973, Cabral led the PAIGC's guerrilla movement (in Portuguese Guinea) against the Portuguese government, which evolved into one of the most successful wars of independence in modern African history. The goal of the conflict was to attain independence for both Portuguese Guinea and Cape Verde. Over the course of the conflict, as the movement captured territory from the Portuguese, Cabral became the de facto leader of a large portion of what became Guinea-Bissau.  In preparation for the independence war, Cabral set up training camps in Ghana with the permission of Kwame Nkrumah. Cabral trained his lieutenants through various techniques, including mock conversations to provide them with effective communication skills that would aid their efforts to mobilize Guinean tribal chiefs to support the PAIGC. Cabral realized the war effort could be sustained only if his troops could be fed and taught to live off the land alongside the larger populace. Being an agronomist, he taught his troops to teach local crop growers better farming techniques, so that they could increase productivity and be able to feed their own family and tribe, as well as the soldiers enlisted in the PAIGC's military wing. When not fighting, PAIGC soldiers would till and plow the fields alongside the local population.  Cabral and the PAIGC also set up a trade-and-barter bazaar system that moved around the country and made staple goods available to the countryside at prices lower than that of colonial store owners. During the war, Cabral also set up a roving hospital and triage station to give medical care to wounded PAIGC soldiers and quality-of-life care to the larger populace, relying on medical supplies garnered from the USSR and Sweden. The bazaars and triage stations were at first stationary, until they came under frequent attack from Portuguese regime forces.
