The correct answer to this open question is the following.
The Trans-Saharan gold and salt trade
The traders were merchants of the North and West African region that traveled in caravans, using the camel to transport people and goods across the dangers of the Sahara Desert. Akan people were involved in the trade, as well as many other tribes.
Of course, they traded salt and gold, which were the most precious resources of the time for the value they represented. Gold was a precious rock with high value, and salt was as important as gold because people used to preserve food. But they also traded animal skins, ivory, silver, sugar, pepper, and slaves.
These people conducted the trade through camel caravans across the desert, that carried the goods to important trade centers such as Timbuktu and Djenne.

Initially, other rulers in Europe were somewhat pleased that the Bourbon monarchy in France was being reduced in power by the effort to make it a constitutional monarchy. But as the French Revolution proceeded, other ruling houses and nobles in Europe felt the threat that such revolutionary fervor could pose to their own positions, and were ready to fight to stamp out the Revolution. Revolutionary France went to war against those other nations, and when Napoleon took over power in France, he continued those wars and won conquests. Napoleon brought the Civil Code that contained some of the basic ideals of the Revolution to other territories that his empire controlled. Even after Napoleon was defeated, the ideas of liberalism that the French Revolution had unleashed remained as a powerful force, and the 19th century would see a recurring series of revolutionary movements across Europe.
