The kings of Ghana became wealthy through a combination of trade, taxation, and control over the region's gold mines. They taxed traders who passed through their territory, particularly those involved in the trans-Saharan trade that brought gold and other goods to the region. Additionally, the kings had control over the lucrative salt and gold trade routes, allowing them to amass wealth from tolls and tariffs. They also controlled the production and distribution of gold, which was a highly valued commodity in the region.
