Mesopotamia and Its Geography
Iraq is a land of diverse environments. In the north-east lie green, undulating plains, gradually rising to tree-covered mountain ranges with clear streams and wild flowers, with enough rainfall to grow crops. Here, agriculture began between 7000 and 6000 BCE. In the north, there is a stretch of upland called a steppe, where animal herding offers people a better livelihood than agriculture – after the winter rains, sheep and goats feed on the grasses and low shrubs that grow here. To the east, tributaries of the Tigris provide routes of communication into the mountains of Iran. The south is a desert – and this is where the first cities and writing emerged (see below). This desert could support cities because the rivers Euphrates and Tigris, which rise in the northern mountains, carry loads of silt (fine mud). When they flood or when their water is let out on to the fields, fertile silt is deposited.
After the Euphrates has entered the desert, its water flows out into small channels. These channels flood their banks and, in the past, functioned as irrigation canals: water could be let into the fields of wheat, barley, peas or lentils when necessary. Of all ancient systems, that of the Roman Empire (Theme 3) included, it was the agriculture of southern Mesopotamia that was the most productive, even though the region did not have sufficient rainfall to grow crops. Not only agriculture, Mesopotamian sheep and goats that grazed on the steppe, the north-eastern plains and the mountain slopes (that is, on tracts too high for the rivers to flood and fertilise) produced meat, milk and wool in abundance. Further, fish was available in rivers and date-palms gave fruit in summer. Let us not, however, make the mistake of thinking that cities grew simply because of rural prosperity. We shall discuss other factors by and by, but first let us be clear about city life.
The Significance Of Urbanism:
Cities and towns are not just places with large populations. It is when an economy develops in spheres other than food production that it becomes an advantage for people to cluster in towns. Urban economies comprise besides food production, trade, manufactures and services. City people, thus, cease to be self-sufficient and depend on the products or services of other (city or village) people. There is continuous interaction among them. For instance, the carver of a stone seal requires bronze tools that he himself cannot make, and coloured stones for the seals that he does not know where to get: his ‘specialisation’ is fine carving, not trading. The bronze tool maker does not himself go out to get the metals, copper and tin. Besides, he needs regular supplies of charcoal for fuel. The division of labour is a mark of urban life. Further, there must be a social organisation in place. Fuel, metal, various stones, wood, etc., come from many different places for city manufacturers. Thus, organised trade and storage is needed. There are deliveries of grain and other food items from the village to the city, and food supplies need to be stored and distributed. Besides, many different activities have to be coordinated: there must be not only stones but also bronze tools and pots available for seal cutters. Obviously, in such a system some people give commands that others obey, and urban economies often require the keeping of written records.
Movement Of Goods To Cities:
However rich the food resources of Mesopotamia, its mineral resources were few. Most parts of the south lacked stones for tools, seals and jewels; the wood of the Iraqi date-palm and poplar was not good enough for carts, cart wheels or boats; and there was no metal for tools, vessels or ornaments. So we can surmise that the ancient Mesopotamians could have traded their abundant textiles and agricultural produce for wood, copper, tin, silver, gold, shell and various stones from Turkey and Iran, or across the Gulf.
These latter regions had mineral resources, but much less scope for agriculture. Regular exchanges – possible only when there was a social organisation – to equip foreign expeditions and direct the exchanges were initiated by the people of southern Mesopotamia. Besides crafts, trade and services, efficient transport is also important for urban development. If it takes too much time, or too much animal feed, to carry grain or charcoal into cities on pack animals or bullock carts, the city economy will not be viable. The cheapest mode of transportation is, everywhere, over water. River boats or barges loaded with sacks of grain are propelled by the current of the river and/or wind, but when animals transport goods, they need to be fed. The canals and natural channels of ancient Mesopotamia were in fact routes of goods transport between large and small settlements, and in the account on the city of Mari later in the chapter, the importance of the Euphrates as a ‘world route’ will become clear.
