The spiritual founder of the Tazerwalt dynasty was Ahmad u Musa, a marabout from the Souss who was born in the mid-15th century and afterwards settled in the Tazerwalt area, where he established a zawiya and attracted hundreds of followers, who came to receive his religious teachings. Ahmad u Musa maintained close relations with the ruling Saadian dynasty and was able to use his religious standing to carve out an enclave of power within the Saadian state. Following his death, Ahmad u Musa's grave became a pilgrimage site, and his offspring inherited much of the wealth and status he had acquired as a spiritual leader.
The Emirate of Tazerwalt
The death of the Saadian Sultan Ahmad al-Mansur in 1603 triggered political instability throughout Morocco, at which point Ahmad u Musa's grandson Bu-Dmi'a seized the opportunity to transform the family's religious status into political power. Naming himself the amir of Tazerwalt, he founded a capital at Iligh and consolidated his control over the region by mobilizing his religious following and tribal alliances. Controlling both overland trade routes and major ports such as Agadir, Bu-Dmi'a extracted the resources needed to raise a sizable army, which he then used to further expand borders eastward. By the mid-17th century, Bu-Dmi'a controlled a wide swath of the Sahara and Morocco south of the Atlas mountains, including important centers of trans-Saharan commerce such as the Draa valley, Sijilmasa, Tuat, and Taghaza. Bu-Dmi'as hegemony, however, was threatened by the rise of the Alaouite dynasty in Tafilalt, who in the late 1650s captured Sijilmasa and eroded much of Tazerwalt's economic power. Bu-Dmi'a died in 1659 and was briefly succeeded by his son Muhammad, but in 1670 the Alaouites razed the capital of Tazerwalt at Iligh, thus cementing their control over Morocco and bringing a definitive end to Tazerwalt's political independence.
Later Years
Following the destruction of Iligh, Ahmad u Musa's descendants lost most of their political power, but were able to leverage their familial connections to the saint to maintain wealth and social prestige as the "House of Iligh." While never directly challenging Alaouite rule, in the 18th and 19th centuries they regained significant political and even military power, enjoying a degree of autonomy that gave them control over much of the Souss region and allowed them to regulate trade and conduct diplomacy with both the ruling Alaouite dynasty and European powers. Today Sidi Ahmad u Musa's zawiya remains a site of pilgrimage and is located in the village of Sidi Ahmed Ou Moussa, which shares his name.
