A first-half goal by Wilson Eduardo separated Angola and Botswana and took the Palancas Negras through to the 2019 Africa Cup of Nations (Afcon) in Egypt.
Angola qualified for their eighth Afcon tournament after an away victory against a rather youthful looking Botswana side.
Needing just a win, former Portugal youth international Eduardo Wilson struck in the 21st minute to seal Angola's passage to the Afcon tournament.
The result saw Angola ignore the other Group I match between Mauritania and Burkina Faso in which the latter won 1-0 but their victory was not enough to take them to Egypt 2019.
