The Islamic State in the Greater Sahara (IS-GS) is an Islamist militant group adhering to the ideology of Salafi Jihadism. IS-GS was formed on 15 May 2015 as the result of a split within the militant group Al-Mourabitoun. The rift was a reaction to the adherence of one of its leaders, Adnan Abu Walid al-Sahraoui, to the Islamic State. From March 2019 to 2022, IS-GS was formally part of the Islamic State – West Africa Province (ISWAP); when it was also called "ISWAP-Greater Sahara". In March 2022, IS declared the province autonomous, separating it from its West Africa Province and naming it Islamic State Sahel Province (ISSP).
