Ikjan
Ikjan was a fortified place in the mountain country of the Kutama Amazigh in northeastern Algeria. At the end of the ninth century the Ismaili missionary Abu Abdallah al-Shi‘i won support among the Kutama and made the area a base for his movement. Their armies went on to overthrow the Aghlabids, and in 909 the Fatimid caliphate was established. Ikjan’s mountain setting formed part of the movement’s early history.
