Here’s a look at Boko Haram, a militant Islamic group working out of Nigeria, whose purpose is to institute Sharia, or Islamic law.


In the local Hausa dialect, Boko Haram means “Western education is forbidden.”

The group also refers to itself as Jama’atu Ahlis Sunna Lidda’awati Wal-Jihad, meaning “People Committed to the Propagation of the Prophet’s Teachings and Jihad.”

Boko Haram militants mainly inhabit areas in the northern states of Nigeria, specifically Yobe, Kano, Bauchi, Borno and Kaduna.

Originally, Boko Haram was referred to locally as the Nigerian Taliban because of their religious similarities to the Taliban.

Boko Haram does not engage in Nigeria’s political system out of an adherence to a fundamentalist form of Islam, which forbids participation unless the system is based on Sharia, or Islamic law.
