Trade Routes Developed
As civilizations grew, becoming more advanced, the demand for certain products, such as copper and tin increased. People began to desire products that were not available in their own lands, such as exotic spices, grains, animals, and so forth.
At first trade was simple. Individuals traded goods amongst one another within their own community, or with individuals from neighboring communities. However, within a few short centuries complex long distance trading routes developed.
Specialized traders known as merchants organized caravans that covered distances of thousands of miles, bringing the goods and products of one society to trade them for goods and products from another society.
