Garamantes
The Garamantes (Ancient Greek: Γαράμαντες, romanized: Garámantes; Latin: Garamantes) were ancient peoples, who may have descended from Berber tribes, Toubou tribes, and Saharan pastoralists and who had settled, at least as early as 1000 BC, in the Fezzan region , where they established a civilization that flourished until its end in the late 7th century AD. The Garamantes first emerged as a major regional power in the mid-2nd century AD and established a kingdom that spanned roughly 180,000 km2 (70,000 sq mi) in the Fezzan region of southern Libya. Their growth and expansion was based on a complex and extensive qanat irrigation system (Berber: foggaras), which supported a strong agricultural economy and a large population.
