How did the kings of ghana use the law of supply and demand to their advantage?

The kings of Ghana used the law of supply and demand to their advantage by limiting the amount of gold available for trade, increasing its value.

Explanation:

According to the law of supply and demand, when there is a high demand of a product but the amount of the good available for trade is scarce - either naturally or forced - the price of the goods will increase. This is what the kings of Ghana did, becoming a strong force in trans-Saharan trade.

because of its location and commercial importance, atlanta was used as a center for military operations and as a supply route by the confederate army during the civil war. therefore, it also became a target for the union army. general william tecumseh sherman and his troops captured the city in 1864.
