History
Before the Portuguese, the coast north of the Congo river belonged to three related Kongo-speaking kingdoms: Loango further north, and Kakongo and Ngoyo, whose lands covered most of today's Cabinda. From the 17th century their ports traded ivory, copper and above all enslaved people with Portuguese, Dutch, English and French ships, and Cabinda Bay became one of the busiest slave-trading anchorages on the coast.
As European powers carved up the region in the 1880s, local chiefs signed the Treaty of Simulambuco with Portugal in 1885, placing the area under Portuguese protection; the Berlin Conference the same year gave the land along the Congo mouth to King Leopold's Congo Free State. This left Cabinda separated from Angola, and it was administered as a distinct protectorate before being run as part of Angola from the mid-20th century.
Oil changed everything. Gulf Oil found large offshore fields in the 1960s, and Cabinda became the source of a large share of Angola's oil. FLEC, the Front for the Liberation of the Enclave of Cabinda, was founded in 1963 and argues that the Simulambuco treaty makes Cabinda a separate territory; the Angolan government regards it as an integral province. Low-level fighting has continued since 1975, a memorandum of understanding was signed with one faction in 2006, but an armed struggle persists.
