How was trade in the past?

In the past, trade was primarily conducted through bartering, where goods and services were exchanged directly without the use of currency. As societies evolved, trade routes emerged, facilitating the exchange of commodities between distant regions, often through overland caravans or maritime shipping. The establishment of currencies and trade agreements further streamlined transactions, fostering economic growth and cultural exchange. Major trade centers, such as the Silk Road and the Mediterranean trade routes, played crucial roles in connecting diverse civilizations.
