Nigeria is made up many different tribes but has three major ones, The Hausa, Igbo and Yoruba. The hausa occupy most of the north and are the most populous. They are almost completely Islamic, with their traditional leaders being Sultans and Emirs. They believe they own Nigeria and try to impose their wishes however they can. The current president is Hausa and an agenda to make Nigeria an Islamic state as been rumored for a while now.
