Season 5 Episode 4: The Roman Invasion of the Sahara

Throughout the early middle ages, Kilwa remained a small settlement, laying in the shadow of the much greater city of Mogadishu.

Hidden in the brackish estuary of the Rufiji River, one of the greatest archaeological finds of the modern era might be waiting: the remains of a still poorly understood ancient trade hub referred to in ancient texts from across the world.  Rhapta, a maritime metropolis, was likely the most influential city of its region, and one which still remains enigmatic.

In this episode, we explore the origins of farming in East Africa, as well as some of the oldest evidence for long-distance trade reaching the region.

Despite being the most widely spoken African language on Earth, KiSwahili originates from a people who are shockingly small in number. However, what the Swahili lacked in numbers, they made up for in influence and fascination. Join us for our sixth season, as we dive into the history of the Swahili coast, and the fascinating history of how its residents became adept city-builders, advanced maritime navigators, sly traders, and the masters of many fascinating civilizations. This includes the greatest Swahili civilization of them all, the Sultanate of Kilwa.

Most histories of the Garamantian kingdom end after its political collapse in the 4th century. However, the archaeological and written record seem to indicate that while the Garamantian kingdom may have died, the civilization that it spawned persisted well into the middle ages. 

Pop histories of the Garamantian civilization often posit that Garama died of thirst: the Garamantes used up the fossil water reserves they had depended on for centuries, sealing the destruction of their advanced irrigation system. However, various pieces of historical evidence cast doubt on this narrative, and the reality is far more complex. Today, we discuss the possibility of rebellions, slave trading, economic decline, and loosening control over their nomadic neighbors as the possible root causes of the rapid changes facing Garamantian society at the end of their civilizational life.

As trade intensifies across the Sahara, the Garamantes become an ever-wealthier civilization. This episode examines how the growth of the Garamantian kingdom influenced the architecture, living standards, religion, and burial practices of the Garamantes.

When Garamantian raids and control of trade routes become too much to bear, the Romans do what they do best: invade their neighbors. In this episode, Roman administrator Lucius Balbus leads a series of legions against the Garamantes in battle.

Horses, carbuncles, gold, salt, and more. What do all these things have in common? They were first traded across the Sahara by the Garamantes. Today's episode discusses the earliest rise of Garamantian trans-Saharan trade, the first documented example of trade across the vast desert.

Brought to the Sahara following the Persian conquest of Egypt, the spread of a new irrigation technology allowed Garamantian civilization to expand dramatically The earliest evidence of a unique Garamantian culture comes from the settlement of Zinkekra, located at the top of a rocky plateau near the Wadi al Ajal. However, settlements gradually drifted further down the valley.   The location at the bottom of these valleys allowed new Garamantian settlements to better take advantage of a technology recently brought to North Africa with the Persian conquest of Egypt. Known as Qanats, or Fouggaras in North Africa, this advanced irrigation technology allowed Garamantian settlements to tap into groundwater reserves without the labor intensive practice of extracting water from wells with buckets. Instead, gravity brought water through the slightly inclined channel and delivered it to the irrigated outlet
