Jorge Ornelas Isaac Sangumba (1944–1982)[citation needed] served as the Foreign Minister of UNITA during the Angolan War of Independence. Sangumba studied in the United States before joining the National Union of Angolan Students (UNEA) in the early 1960s. In 1965 he became UNEA's representative for external affairs, a precursor for his future appointment as UNITA's Foreign Minister in August 1969. Jonas Savimbi, leader of UNITA, allegedly ordered Sangumba's assassination along with several other potential rivals for leadership of UNITA during the Angolan Civil War.
