what effect did the redrawing of national boudries by europeans have on the nation bulding in african countries?

Europe's arbitrary post-colonial borders left Africans bunched into countries that don't represent their heritage, a contradiction that still troubles them today.

When the nations of Nigeria and Cameroon went to settle a border dispute in 2002, in which both countries claimed an oil-rich peninsula about the size of El Paso, they didn't cite ancient cultural claims to the land, nor the preferences of its inhabitants, nor even their own national interests.
