Why the origin of the Bubi people is considered controversial
It is believed that the “Bantu” came from the sources of the Nile, Ubangui and Congo. Among the groups are the union of Pygmies and the Camites or Ethiopians. The second group consists of the Negritos themselves and the Hottentots [Khoisan], the latter group being the most numerous. The first group, of taller stature and lighter colouring, is made up of the Bamasa, the Sangana, the Nzemzem and all the Fang, including the Yaounde, the Bulus of Cameroon, the Ntumu, the Bujeba, etc. The second group includes the Ibalas, Batangas, Subus, Gumbas of Cameroon, the Pongües of Gabon, the Bengas, the Kombes, Balengues and Bapukus and finally the Bubis of Fernando Poo.
The departure of so many people travelling through the nearly-impassable African jungles, meant that people split up into smaller groups.
Those who would end up at Bioko island travelled down the Sanga River, changed direction, passed the Molundu, Misum and headed further downstream the sources of the Kom River, a tributary of the Ntem or Campo River, and continued on their way without leaving the banks of the Campo. They reached the Atlantic. Here they made a halt and settled at the mouth of the Campo River and Kribi (Cameroon) for some time.
After reaching the shore, some of these tribes settled in the surroundings of Campo river, with access to fresh water, crops and healthy environment, the settlement and the populations increased. It was not long before others found out about the spot, and more powerful tribes diverted their attention towards capturing people for the slave trade form the area. Eventually, seeing their settlement invaded, the people decided to change their habitat in order to escape.
