protectorate · Central and Southern Africa

Portuguese Congo

1885 CE – 1975 CE · capital Cabinda

The Portuguese protectorate of Cabinda, an enclave north of the Congo River whose oil and separatism shape Angolan politics.

Origins

Portugal had traded on the Loango coast for centuries. To secure its claim against France and Leopold II, it signed the Treaty of Simulambuco with the princes and chiefs of Cabinda on 1 February 1885, establishing a protectorate over territory once ruled by the Kingdom of Ngoyo and the Kingdom of Kakongo.

Rule and society

The Berlin Conference left Cabinda separated from Portuguese Angola by a strip of land given to the Congo Free State. It was governed from Cabinda town, at first separately and from the 1920s increasingly as a district of Angola. Timber, cocoa and coffee were exported, and from the 1960s offshore oil discovered by Cabinda Gulf Oil became the enclave's main resource.

Decline and legacy

Separatists of the Front for the Liberation of the Enclave of Cabinda claimed independence, but the 1975 Alvor Agreement made Cabinda part of independent Angola, where it remains a province with a low-level separatist conflict.
