<h3>The Great Ancient Empires Trading</h3>
Empires were the trading centers in their respective regions where different trade routes converged.

Each had its currency, which reflected its culture and emblems and served as a wild card to facilitate exchanges between producers and traders.
<h3>The First Banks Trading</h3>
The first banks appeared in the Middle Ages, long before money was central to today's society, thanks to the invention and expansion of capitalism in the 18th century.

Later, the expansion of European empires worldwide brought with it mercantilism.
