Wouri River
The first European records of the people of the Douala region around the Wouri estuary noted that they were engaged in fishing and agriculture to some extent, but primarily were traders with the people of the interior via the Wouri River and its tributaries, and via the Dibamba, Kwa Kwa and Mungo rivers. In the 19th century they were bartering palm oil, palm kernels and ivory for European goods. Their leaders, whom the Europeans called "kings", came from the two lineages of Bell and Akwa.
