Between the first century BC and the fourth century AD, several expeditions and explorations to Lake Chad and western Africa were conducted by groups of military and commercial units of Romans who moved across the Sahara and into the interior of Africa and its coast. However, there was a more significant Roman and Greek presence in modern-day Eritrea and Ethiopia. The primary motivation for the expeditions was to secure sources of gold and spices from Axumite piracies. [1]
Romans referred to sub-Saharan Africa as Aethiopia (Ethiopia), which referred to the people's "burned" skin. They also had available memoirs of the ancient Carthage explorer, Hanno the Navigator, being referenced by the Roman Pliny the Elder (c. 23–79) [2] and the Greek Arrian of Nicomedia (c. 86–160). [3] However, how much they were read, believed, or found interesting to the Romans is unknown.
The Romans organized expeditions to cross the Sahara along five different routes:
All these expeditions were supported by legionaries and had mainly a commercial purpose. Only the one conducted by emperor Nero seemed to be a preparative for the conquest of Ethiopia or Nubia; in 62 AD, two legionaries explored the sources of the Nile. [5]
One of the main objectives of the explorations was to locate and obtain gold, using camels to transport it overland back to Roman provinces on the Mediterranean coast. [6]
The explorations near the coasts were supported by Roman ships and deeply related to overseas commerce.
The Romans conducted five main explorations: two in the western Sahara, two in the central Sahara, and one in the area of Lake Chad.
In western Sahara there were two Roman expeditions but, just south of the Atlas Mountains:
From the first century AD there is evidence (coins and fibulae) of Roman commerce and contacts in Akjoujt and Tamkartkart near Tichit in Mauritania.
The two main explorations/expeditions in the central Sahara were:
However some historians (like Susan Raven [11] ) believe that there was even another Roman expedition to sub-Saharan central Africa: the one of Valerius Festus, that could have reached the equatorial Africa thanks to the Niger River.
The Roman vassal king Juba II organized successful trade from the area of Volubilis. Pliny the Elder, who was not only an author but also a military officer, drawing upon the accounts of Juba II, king of Mauretania in the first century AD, stated that a Roman expedition from Mauritania visited the islands of the archipelago of the Canaries and Madeira around 10 AD and found great ruins but no population, only dogs (the basis of the name the Canaries).
According to Pliny the Elder, an expedition of Mauretanians sent by Juba II to the archipelago visited the islands: when King Juba II dispatched a contingent to re-open the dye production facility at Mogador (historical name of Essaouira, Morocco) in the early 1st century AD, Juba's naval force was subsequently sent to explore the Canary Islands, and possibly Madeira, using Mogador as their base.
Other Roman coins have been found in Nigeria and Niger, and also in Guinea, Togo, and Ghana. However, it is much more likely that all these coins were introduced at a much later date than that there was direct Roman intercourse so far down the western coast. No single article unmistakably originating in Africa south of the Equator has been discovered in the Graeco-Roman world or in contemporary Arabia, nor is there any mention of such an article in written records: while the coins are the only ancient European or Arabian articles that have been found in the central parts of Africa. [14]
The Romans had two naval outposts in the Atlantic coast of Africa: Sala Colonia near present Rabat and Mogador in southern Morocco (north of Agadir). The island of Mogador prospered from the local purple dye-making industry (highly esteemed in imperial Rome) from the reigns of Augustus until Septimius Severus. Augustus, based on the discovery of a sunken merchant ship from southern Hispania in the Djibouti area (found by his adoptive son Gaius Caesar when he sailed toward Aden), wanted to organize an expedition from Egypt to Mogador and Sala around Africa, but it seems that it never took place.
Chad is one of the 47 landlocked countries in the world and is located in North Central Africa, measuring 1,284,000 square kilometers (495,755 sq mi), nearly twice the size of France and slightly more than three times the size of California. Most of its ethnically and linguistically diverse population lives in the south, with densities ranging from 54 persons per square kilometer in the Logone River basin to 0.1 persons in the northern B.E.T. (Borkou-Ennedi-Tibesti) desert region, which itself is larger than France. The capital city of N'Djaména, situated at the confluence of the Chari and Logone Rivers, is cosmopolitan in nature, with a current population in excess of 700,000 people.
The Niger River is the main river of West Africa, extending about 4,180 kilometres. Its drainage basin is 2,117,700 km2 (817,600 sq mi) in area. Its source is in the Guinea Highlands in south-eastern Guinea near the Sierra Leone border. It runs in a crescent shape through Mali, Niger, on the border with Benin and then through Nigeria, discharging through a massive delta, known as the Niger Delta, into the Gulf of Guinea in the Atlantic Ocean. The Niger is the third-longest river in Africa, exceeded by the Nile and the Congo River. Its main tributary is the Benue River.
Geographical exploration, sometimes considered the default meaning for the more general term exploration, refers to the practice of discovering remote lands and regions of the planet Earth. It is studied by geographers and historians.
The Sahara is a desert spanning across North Africa. With an area of 9,200,000 square kilometres (3,600,000 sq mi), it is the largest hot desert in the world and the third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic.
Lucius Cornelius Balbus, often referred to as Lucius Cornelius Balbus Minor, was a Roman politician and General. Similarly to his uncle Balbus the Elder, Balbus Minor was also born in Gades with Punic origins, and became a distinguished member of the gens Cornelia through adoption. Despite his Phoenician ancestry, Balbus rendered valuable services to the early Roman Empire, most notably by serving as the proconsul of Africa in 21 BC and leading an expedition to sub-Saharan Africa. He was also known to be a close friend and trusted associate of Julius Caesar.
Fezzan is the southwestern region of modern Libya. It is largely desert, but broken by mountains, uplands, and dry river valleys (wadis) in the north, where oases enable ancient towns and villages to survive deep in the otherwise inhospitable Sahara Desert. The term originally applied to the land beyond the coastal strip of Africa proconsularis, including the Nafusa and extending west of modern Libya over Ouargla and Illizi. As these Berber areas came to be associated with the regions of Tripoli, Cirta or Algiers, the name was increasingly applied to the arid areas south of Tripolitania.
The Garamantes were ancient peoples, who may have descended from Berber tribes, Toubou tribes, and Saharan pastoralists that settled in the Fezzan region by at least 1000 BC and 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, which supported a strong agricultural economy and a 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 pinnacle, the Garamantian kingdom established and maintained a "standard of living far superior to that of any other ancient Saharan society" and was composed of "brilliant farmers, resourceful engineers, and enterprising merchants who produced a remarkable civilization."
The Tibesti Mountains are a mountain range in the central Sahara, primarily located in the extreme north of Chad, with a small portion located in southern Libya. The highest peak in the range, Emi Koussi, lies to the south at a height of 3,415 meters (11,204 ft) and is the highest point in both Chad and the Sahara. Bikku Bitti, the highest peak in Libya, is located in the north of the range. The central third of the Tibesti is of volcanic origin and consists of five volcanoes topped by large depressions: Emi Koussi, Tarso Toon, Tarso Voon, Tarso Yega and Toussidé. Major lava flows have formed vast plateaus that overlie Paleozoic sandstone. The volcanic activity was the result of a continental hotspot that arose during the Oligocene and continued in some places until the Holocene, creating fumaroles, hot springs, mud pools and deposits of natron and sulfur. Erosion has shaped volcanic spires and carved an extensive network of canyons through which run rivers subject to highly irregular flows that are rapidly lost to the desert sands.
Trans-Saharan trade is trade between sub-Saharan Africa and North Africa that requires travel across the Sahara. Though this trade began in prehistoric times, the peak of trade extended from the 8th century until the early 17th century CE. The Sahara once had a different climate and environment. In Libya and Algeria, from at least 7000 BCE, pastoralism, large settlements and pottery were present. Cattle were introduced to the Central Sahara (Ahaggar) between 4000 to 3500 BCE. Remarkable rock paintings in arid regions portray flora and fauna that are not present in the modern desert.
Saharan rock art is a significant area of archaeological study focusing on artwork carved or painted on the natural rocks of the central Sahara desert. The rock art dates from numerous periods starting c. 12,000 years ago, and is significant because it shows the culture of ancient African societies.
Mauretania Tingitana was a Roman province, coinciding roughly with the northern part of present-day Morocco. The territory stretched from the northern peninsula opposite Gibraltar, to Sala Colonia and Volubilis to the south, and as far east as the Mulucha river. Its capital city was Tingis, which is the modern Tangier. Other major cities of the province were Iulia Valentia Banasa, Septem, Rusadir, Lixus and Tamuda.
The Toubou or Tubu are an ethnic group native to the Tibesti Mountains that inhabit the central Sahara in northern Chad, southern Libya, northeastern Niger, and northwestern Sudan. They live either as herders and nomads or as farmers near oases. Their society is clan-based, with each clan having certain oases, pastures and wells.
Desert exploration is the deliberate and scientific exploration of deserts, the arid regions of the earth. It is only incidentally concerned with the culture and livelihood of native desert dwellers. People have struggled to live in deserts and the surrounding semi-arid lands for millennia. Nomads have moved their flocks and herds to wherever grazing is available, and oases have provided opportunities for a more settled way of life. Many, such as the Bushmen in the Kalahari, the Aborigines in Australia and various Indigenous peoples of the Americas, were originally hunter-gatherers. Many trade routes have been forged across deserts, especially across the Sahara Desert, and traditionally were used by caravans of camels carrying salt, gold, ivory and other goods. Large numbers of slaves were also taken northwards across the Sahara. Today, some mineral extraction also takes place in deserts, and the uninterrupted sunlight gives potential for the capture of large quantities of solar energy.
The Association for Promoting the Discovery of the Interior Parts of Africa, founded in London on 9 June 1788, was a British club dedicated to the exploration of West Africa, with the mission of discovering the origin and course of the Niger River and the location of Timbuktu, the "lost city" of gold. The formation of this group was effectively the "beginning of the age of African exploration".
Agisymba was an unidentified country located in Africa mentioned by Ptolemy in the middle of the 2nd century AD.
Mogador Island is the main island of the Iles Purpuraires near Essaouira in Morocco. It is about 3 kilometres long and 1.5 kilometres wide, and lies about 1.5 kilometres from Essaouira.
The Roman exploration of the Nile River under Nero was a Roman attempt to reach the sources of the Nile. It was organized by emperor Nero in 60–61 AD.
The Chad–Niger border is 1,196 km in length and runs from the tripoint with Libya in the north, to the tripoint with Nigeria in the south.
