Territory of the Islamic State – West Africa Province

The Islamic State – West Africa Province (ISWAP), officially known as Wilāyat Garb Ifrīqīyā (West Africa Province), controls territory in and around the Lake Chad Basin. Although ISWAP does not maintain full authority over all territories where it operates, it exercises stronger control in rural regions than the Nigerian government and governs an estimated 800,000–3,000,000 civilians through a combination of military presence, local administration, and taxation systems.
