Cause → Event → Consequence
The 1884–85 Treaty of Berlin among European powers formalized the Scramble for Africa, prompting Portugal to assert sovereignty beyond its long-held coastal trading ports and incorporate nearby territories before rival powers could claim them.
In February 1885, emissaries of the Portuguese Crown and the princes and notables of N'Goyo signed the Treaty of Simulambuco, peacefully placing Cabinda under Portuguese protection and creating three sub-territories: Cacongo, Loango, and Ngoio.
Cabinda was incorporated into the Portuguese Empire as a protectorate separate from Angola, a distinction that would later underpin separatist arguments, particularly citing Article 2's guarantee of territorial integrity, and fuel a prolonged conflict over Cabinda's status as an Angolan exclave.
Political Outcome
Cabinda became a protectorate of the Portuguese Crown, separated administratively from Angola, with the princes and chiefs formally recognizing Portuguese sovereignty.
N'Goyo Kingdom exercised independent governance over Cabinda territory
Cabinda placed under Portuguese protectorate with Portugal obligated to maintain territorial integrity
