Movement of Goods into Cities
In ancient Mesopotamia, while food resources were plentiful, mineral resources were scarce. Areas in the south lacked sufficient stones for tools and lacked metals, impacting their ability to create useful items. To combat these shortages, Mesopotamians likely traded their abundant textiles and agricultural products for essential materials such as wood, copper, tin, silver, gold, shell, and various stones from regions like Turkey, Iran, or across the Gulf. Such trade was only viable due to a well-organized social system to manage foreign expeditions and exchanges.
Efficient transport mechanisms also played a vital role in urban development. If transporting goods, particularly essential items like grain or charcoal, was inefficient, the economy of the city would struggle. Among several transport modes, water transport emerged as the cheapest and most efficient. River boats and barges tended to rely on natural currents or wind, requiring far less animal feed compared to land transport methods like pack animals or bullock carts. The numerous canals and natural waterways in Mesopotamia served as vital routes for moving goods between settlements, reinforcing the importance of water routes evident in the later discussion of the city of Mari and the Euphrates River as a significant trade corridor.
