The Berlin Conference compelled Portugal to move towards the immediate occupation of all the territories it laid claim to but had been unable to effectively conquer. The territory of Cabinda (province), to the north of the river Zaire, was also ceded to Portugal on the legal basis of the Treaty of Simulambuko Protectorate, concluded between the Portuguese Crown and the princes of Cabinda in 1885. In the 19th century they slowly and hesitantly began to establish themselves in the interior. Angola as a Portuguese colony encompassing the present territory was not established before the end of the 19th century, and "effective occupation", as required by the Berlin Conference (1884) was achieved only by the 1920s.
