The Garamantes (Berber: aɣrem, "castle") were an ancient civilisation based primarily in present day Libya. They most likely descended from Iron Age Berber tribes from the Sahara, although the earliest known record of their existence dates to the fifth century BC. Little remains of their civilization, as their epigraphy is nearly indecipherable; much of what is known comes from contemporaneous Greek and Roman foreign accounts and modern archaeological findings.
The Garamantes emerged as a major regional power in the mid second century AD, establishing a kingdom that spanned roughly 70,000 square miles in the Fezzan region of southern Libya. Their growth and expansion rested on a complex and extensive qanat irrigation system (known as foggaras in Berber), which supported a strong agricultural economy and large population. They subsequently developed the first urban society in a major desert that was not centered on a river system; their largest town, Garama, had a population of around four thousand, with an additional six thousand living in surrounding suburban areas.
At its height, the Garamantian kingdom enjoyed a "standard of living far superior to that of any other ancient Saharan society." The Garamantes annexed and dominated surrounding tribes and relied heavily on enslaved peoples for their prosperity. The state began to decline in the fifth century as their source of water diminished, causing their kingdom to fragment and ultimately become annexed by surrounding powers.
Until the mid 20th century, the Garamantes were believed to be a small and minor desert tribe. Beginning in the 1960s, archaeological excavations have revealed the Garamantes to be "brilliant farmers, resourceful engineers, and enterprising merchants who produced a remarkable civilization."
The Garamantes were probably present as a tribe in the Fezzan by 1000 BC. They appear in the written record for the first time in the 5th century BC: according to Herodotus, they were "a very great nation" who herded cattle, farmed dates, and hunted the Ethiopian cave-dwellers who lived in the desert, from four-horse chariots. Roman depictions describe them as bearing ritual scars and tattoos. Tacitus wrote that they assisted the rebel Tacfarinas and raided Roman coastal settlements. According to Pliny the Elder, Romans eventually grew tired of Garamantian raiding and Lucius Cornelius Balbus captured 15 of their settlements in 19 BC. In 202, Septimius Severus captured the capital city of Garama.
By around 150 AD the Garamantian kingdom (in today's central Libya (Fezzan), principally along the still existing Wadi al-Ajal), covered 180,000 square kilometres in modern-day southern Libya. It lasted from about 400 BC to 600 AD.
The decline of the Garamantian culture may have been connected to worsening climatic conditions, or overuse of water resources. What is desert today was once fairly good agricultural land and was enhanced through the Garamantian irrigation system 1,500 years ago. As fossil water is a non-renewable resource, over the six centuries of the Garamantian kingdom, the ground water level fell. The kingdom declined and fragmented.
The last news about Garamantes dates back to the VI-VII century. From Byzantine sources it is known that in 569 their king, probably a client king of the Byzantines, accepted Christianity. Muslim documents later state that in 668 the king of the Garamants was imprisoned and dragged away in chains. Eventually the whole region was absorbed into the area of Islamic influence.
In the 1960s, archaeologists excavated part of the Garamantes' capital at modern Germa (situated around 150 km west of modern-day Sabha) and named it Garama (an earlier capital, Zinchecra, was located not far from the later Garama). Current research indicates that the Garamantes had about eight major towns, three of which have been examined as of 2004[update]. In addition they had a large number of other settlements. Garama had a population of around four thousand and another six thousand living in villages within a 5 km radius.
The Garamantes were farmers and merchants. Their diet consisted of grapes, figs, barley, and wheat. They traded wheat, salt and slaves in exchange for imported wine and olive oil, oil lamps and Roman tableware. According to Strabo and Pliny, the Garamantes quarried amazonite in the Tibesti Mountains. In 2011, Nikita et al. reported that Garamantes skeletons do not suggest regular warfare or strenuous activities. "The Garamantes exhibited low sexual dimorphism in the upper limbs, which is consistent to the pattern found in agricultural populations and implies that the engagement of males in warfare and construction works was not particularly intense. [...] the Garamantes did not appear systematically more robust than other North African populations occupying less harsh environments, indicating that life in the Sahara did not require particularly strenuous daily activities."
Archaeological ruins associated with the Garamantian kingdom include numerous tombs, forts, and cemeteries. The Garamantes constructed a network of tunnels, and shafts to mine the fossil water from under the limestone layer under the desert sand. The dating of these foggara is disputed, they appear between 200 BC to 200 AD but continued to be in use until at least the 7th century and perhaps later. The network of tunnels is known to Berbers as Foggaras. The network allowed agriculture to flourish, and used a system of slave labor to keep it maintained. Marta Mirazón Lahr conducted research on skeletons from Fezzan dating to the Roman era and found that the skeletons most closely matched Neolithic sub-saharan African samples, from Chad, Mali, and Niger. Lahr associates these remains with the Garamantes, and concludes that the Garamantes had connections with both sub-saharan and northern Africa.
