How did the kings of Ghana become wealthy

Between the 9th and 11th centuries C. E., the kingdom of Ghana was so rich that its dogs wore golden collars, and its horses, which were adorned with silken rope halters, slept on plush carpets. Based on animal luxuries alone, it is no wonder that foreigners touted Ghana's kings as the richest men in the world. Gradually, Ghana grew very rich, due in large part to the trans - Saharan trade. The ghana required traders to give him a percentage of the products they were trading. If a trader was trading in gold, he was required to pay the ghana part of his gold. The ghana also placed a tax on the local goldmines.

The Kings of Ghana became wealthy as a result of the trade in gold. Ghana was located close to the gold fields of Bure. Gold was often exchanged for salt through the Trans Saharan trade.
