What policy did Portugal follow with its colony of Angola

The colonial history of Angola is usually considered to run from the appearance of the Portuguese under Diogo Cão in 1482 (Congo) or 1484 (Angolan coast) until the independence of Angola in 1975. Settlement did not begin until Novais's establishment of São Paulo de Loanda (Luanda) in 1575, however, and the Portuguese government only formally incorporated Angola as a colony in 1655 [citation needed] or on May 12, 1886.

Portugal fought a long war to try to hold onto Angola.
