Sous
Medieval Arab geographers split the Sous region into two sub-regions: al-Sūs al-Aqṣā, or "farther Sus", and al-Sūs al-Adnā, or "nearer Sus". Sus al-Aqsa was the southern/western part, and Sus al-Adna was the northern/eastern part; however, there were never any exact boundaries between the two. The capital of the Sous was at Igli. There was also a ribat at Massa near the Atlantic coast.
