António Nabuco Sebastião Dembo (1944 – February 25, 2002)[1] was an Angolan engineer, politician, diplomat and military commander.
His secondary education was at El Harrach and École Nationale d'Ingénieurs et Techniciens d'Algérie in Algeria.
After the war turned against UNITA in 2001–2002, Dembo's forces were constantly on the run from government troops.
However, Dembo, who was also wounded in the same attack that killed Savimbi, and already weakened by diabetes, died three days later.
Consistent with this pre-ordained succession, Dembo assumed leadership of UNITA immediately following Savimbi's death in combat.
