One thing that all of Africa has in common is its ethnicity amongst its diverse cultures which are evidently broken into tribes.

Africa in general has over 2,000 tribes and a few that have faced extinction because of intermarriages given other factors.
They are just too many tribes; you cannot finish them all.
However, much as Africa finds so much pride in its many tribes, these very tribes have become a menace to post-independent Africa.
They have been incentives to large scale murder, corruption, poverty; to mention but a few evils.
For instance, in the 1994 Rwandan genocide, the minority Tutsi had their heads, limbs and other body parts “danced to” by the Hutus who were the genocidaires.
Tribalism had reduced this tribal group into blood thirsty animals who selfishly wanted to possess the whole Rwandan cake without the Tutsi bottlenecks.
It is also a reason we Africans are the most dangerously corrupt mammals in the globe, this identity is highly developed because in our small distinguished tribes, our vying for public goods is terribly accelerated.
We have come to accept tribalism as a normal way of making the frogs in our tribal ponds fat and learnt to reduce the interests of others towards our own.
To every one’s common sense, African highly placed officers in various companies and institutions (Government or Private), immensely work their way into deploying their tribal sisters and brothers to occupy the juiciest of positions.This is a deadly bonanza!
Deadly in a way that, in most cases, a highly placed person in an organisation will not adequately monitor his tribesman or relative in their duties, lest he stumble a brother.
In return incompetence finds its way into the already vulnerable company, which later leads to losses in a company; unemployment and poverty in both a short and long run.
This kind of social affair is also a master behind the segregative lifestyle that surpasses the African society with all kinds of baseless stereotypes.
You will find a Muganda saying; “I cannot associate with a Mukiga, those people are so violent”, and an Acholi will with no evidence say, “Baganda women are proud”, even if he has never crossed Karuma Bridge to stay in Buganda.
What evidence is there that an Acholi, a Mukiga or whatsoever is like this and that?
It is all encompassed in Tribalism that brands the people from this tribe-that, which they are not.
Ever heard or seen these stereotypes happen in Europe where there are no tribes?
As an African author said it, “Tribalism is the sweet and sour pork of African life”.
