Nigeria is a multi tribalistic nation with numerous ethnicities found in each of the tribes and that I think is one the beauties of the most populous black nation. The problems of tribalism in our dear nation is one of the dividing tools of our political leaders who uses it to incite hatred and war amongst us in other to keep us divided because they know that if we come together as one people we all will know that our primary problem as a nation is because of the kind of political leaders that's driven the affairs of this nation over the years.
So even if we all use one unified language, these leaders will still use other means to cause tribal enmity amongst us. So the earlier we all accept that we are a country of multiple tribes and treat every tribe with utmost respect and as important as others the better for us. We all must accept that we have one general problem as a people and that's the the kind of greedy and extremely selfish political leaders that are governing the affairs of this nation.
