Douala Local Customs

I am not sure if the following applies to the whole of Cameroon but it does apply to its Western part.
Every village or few villages are a territory of a tribe. Every tribe has a chief. If we read deep into the history of African tribes, we'll see that normally a chief had few wives. You'd think that with the Christianity monogamy was completely accepted by the tribes, you'd be quite wrong.
Until now the chief of the village (called "grand-pere" - grandfather - despite of his age) is entitled of having few wives. Normally, being a heir of the village he would inherit the previous "grand-pere"'s wives. But of course nowadays no man would agree to marry his own mother or grandmother.
Anyway, whether you like it or now, a "grand-pere" is entitled of taking at least one more wife.
And it happens!!! When I heard about this taking place in modern society, first question I asked was: 'So... how does the church look at it?' I never got a definite answer but I understood that the second wedding doesnt take place in a church. And a wife stays in a village and very rare she would be taken to live in a big city. She is usually younger (or they!) and their roles is to take care of heir's possessions in the village and give him children.
So... contradiction? YES. But... a normal thing out there. By the way: in the village if the man has enough to provide, he can take as many wives as he wants...
