English speaking Southwestern Cameroon might be moving towards independence from French speaking Cameroon. Whether Southwestern Cameroon seeks to realign with Nigeria like the English speaking Northwestern Cameroonians did in 1961 is another issue.
From a genetics standpoint unless I am mistaken I think that DNA testing is taking African Americans back to the Southwestern grassland region in Cameroon, specifically to the Tikar people (Bamileke, Bamoun etc). It also looks like the oil producing sector in Cameroon is in the English speaking regions. If I got any part incorrect, the please correct my entries.
Biafra and Southern Cameroons might 'join forces to achieve independence'
