Mohammed Yusuf, Nigerian militant leader, founded Boko Haram (born 1970)

Mohammed Yusuf, also known as Ustaz Mohammed Yusuf, was a Nigerian militant who founded the Islamist militant group Boko Haram in 2002. He was its leader until he was killed during the 2009 Boko Haram uprising.

Boko Haram, officially known as Jama'at Ahl al-Sunna li al-Da'wa wa al-Jihad, is a self-proclaimed jihadist militant group based in northeastern Nigeria and also active in Chad, Niger, northern Cameroon, and Mali. In 2016, the group split, resulting in the emergence of a hostile faction known as the Islamic State's West Africa Province.
