The Republic of Cabinda, currently occupied by Angola, traces its
claims to self-sovereignty to its initial status as a Portuguese
protectorate, known as the Portuguese Congo. This protectorate had a
separate history and legal status from that of the much larger
Portuguese West Africa, dating to its inception on 19 September 1883
and confirmed by the Treaty of Simulambuco and the Berlin Conference in
1885. Its closest political predecessor was the iron age N'goyo
kingdom, which sought voluntarily incorporation into the Portuguese
Empire as a way of obtaining protection from hostile neighboring states.
