Trade

Trade and industry played a major role in the development of Bronze Age civilizations. With artefacts of the Indus Valley civilization found in ancient Mesopotamia and Egypt, it is clear that these civilizations were not only in touch with one another, but also trading. Early long-distance trade was limited almost exclusively to luxury goods like spices, textiles, and precious metals. Not only did this make cities with ample amounts of these products extremely rich, but it also led to an intermingling of cultures for the first time in history.

Trade routes were not just on land. The first and most extensive trade routes were along rivers such as the Nile, the Tigris, and the Euphrates, which led to the growth of cities on the banks of these rivers. The later domestication of camels also helped encourage trade routes overland, linking the Indus Valley with the Mediterranean. This further led to towns sprouting up everywhere there was a pit-stop or caravan-to-ship port.
