            "description": "\"Of the various axes of Ifè’s interaction sphere, none was as important as the northern axis. This strategic area linked Ilé-Ifè with the trade termini on the River Niger and gave the Yorùbá world access to the commercial traffic between the Western Sudan and the Mediterranean. Saharan copper and salt, as well as Mediterranean and Chinese silk and other clothing materials, were entering the Yorùbá region from across the Niger by the eleventh or twelfth century in exchange for sundry rain forest goods, of which Ifè glass beads and ivory were the most highly prized. Therefore, early in its development, Ilé-Ifè employed military and diplomatic strategies to open up and protect the trade routes to the River Niger, especially between Moshi and Osin tributaries. These efforts are encapsulated in the oral traditions regarding the activities of Òrànmíyàn, who is said to have launched military campaigns in the River Niger area. The stories of this legendary figure reveal Ilé-Ifè’s efforts to secure the safe passage of its exports and imports across the river. Indeed, Ifè trading stations were located in this zone of trading termini, in addition to several Yorùbá-speaking communities that occupied a 310-kilometer stretch of land on both banks of River Niger for most of the Classical period. This was a zone of transition in which trading stations, and port towns and villages received exports from Ilé-Ifè and other parts of the Yorùbá world and imports from the Sudan.\"§REF§(Ogundiran 2020: 115)§REF§"

            "description": "The following quote suggests that trading ports on the Gambia River were likely present. “The Senegambia’s link to the expansive interior trade incorporated several commercial complexes that were connected to the major empires in West Africa besides Mali to the north and Jolof to the east, allowing the flow of a variety of foreign commodities into the region. Part of this conglomerate of networks made use of the Gambia River to gain salt, rice, grasses, and dried fish that would be bartered for iron, cloth, kola, and in all likelihood luxury items (a notable portion of which were of European origin) that until that time could only be obtained from interior markets.” §REF§ (Gijanto 2016, 31-32) Gijanto, Liza. 2016.

Before the second half of the nineteenth century, there were few ports between the Nile and the Kagera river, the latter approximately representing Buganda's southern extremity. There existed, rather, numerous smaller landing stages which were used according to season. [...] By the late nineteenth century, the port of Munyonyo had also become established on the eastward-facing shore between modern-day Entebbe and Kampala. The origins of this port are unclear, but it first came to prominence in the late 1860s when Mutesa established one of his 'capitals' there.\"§REF§(Reid 2010: 238-240) Seshat URL: https://www.zotero.org/groups/1051264/seshat_databank/collections/GWWIKDDM/items/2H64W34U/collection.§REF§"

The Thames served as the highway by which nearly every one of England’s migrant groups penetrated its interior. Usually, they settled along its banks – another reason why the southeast is the most populous part of England. Later, the Thames, along with other major rivers (the Severn to the west; the Mersey, the Great Ouse, Humber, Trent, Tyne, and Tees to the north: map 1), served as principal highways and trade routes. In the eighteenth century, they would be linked in a great national canal system. Though England had a system of roads emanating from London as first laid down by the Romans, water transportation (around the coast or, internally, via the river system) remained the cheapest and safest way to travel or to ship goods.”§REF§(Bucholz et al 2013: 13-14) Bucholz, Robert, Newton Key, and R.O.
