Wagadouโs Gold Tolls: Taxing the Trans-Saharan Arteries
During the 11th century, the rulers of the Wagadou Empire, remembered across early Arabic chronicles as

Ghana, established supreme financial power across the Sahel without operating a single active gold mine. Wagadouโs monarchs derived their wealth by positioning their administrative capital at Koumbi Saleh directly between the Saharan salt mines of Taghaza to the north and the alluvial gold fields of Bambuk to the south. As the geographer al-Bakri documented in his 1068 treatise, King Tunka Manin levied an exact transit duty of one gold dinar on every donkey load of salt entering the imperial borders, and two gold dinars on every donkey load departing. Wagadou deployed royal cavalry squadrons to safeguard the desert caravan trails, while the sovereign exercised an absolute crown monopoly over all raw gold nuggets found in the realm to prevent market inflation. By monopolizing transit access and logistics protection rather than physical extraction, Wagadou maintained a commercial hegemony that dictated terms of exchange between Mediterranean merchants and Sub-Saharan miners for generations.
Why today: This medieval customs monopoly mirrors the leverage governing global energy transit this morning, where soaring tanker rates of $20 per barrel and maritime bottlenecks across the Strait of Hormuz demonstrate that controlling transit corridors matters far more than controlling the wells.
