Well...these are the tribes that speak with one voice in Nigeria at the moment. Your guess is as good as mine.

Fulani
That is why they're progressing more than all others and dictating the pace of development and even who lives or dies. Imagine a tribe that never condemns their no matter the crimes they commit. Jail them and they'll use their foot soldiers to release them. The Ibarapa warlord, Isikilu Wakili is a free man as a result of this. The attack on Jos prison was reportedly a plan to free Fulani bandits. What a tribe that love their own at a time others vilify theirs. Some even forget their own warriors in prison.

Igbo
Igbo have never really been a united tribe until colonialists came. What I have noticed about the Igbo is that the tribe comes together in times of crisis. Presently, there is crisis in Igbo land. The hatred by Nigerians has united Ndigbo more than any other presently. Imagine even the vacillating Ohaneze and politicians solidly behind Nnamdi Kanu. This is no longer the time for business as usual when politicians of Igbo extraction think only about self advancement. Igbo are speaking with one voice on the issue of victimization.

Benin
You cannot beat this great tribe in terms of unity. In fact, when you approach a Bini girl, the first thing she would want to know is if you're Bini. This tribe doesn't just have a rich culture, they love themselves and would accomplish a lot.
