Africa's democratic transition is back in the spotlight. The concern is no longer the stranglehold of autocrats, but the hijacking of the democratic process by tribal politics. Kenya's 2007-08 post-election violence revealed the extent to which tribal forces could quickly bring a country to the brink of civil war. The challenge to democracy in Africa is not the prevalence of ethnic diversity, but the use of identity politics to promote narrow tribal interests. It is tribalism. There are those who argue that tribalism is a result of arbitrary post-colonial boundaries that force different communities to live within artificial borders.
