Mesopotamia, Mormons and the world’s first cities

by Edward Pegler on 22 October, 2010

What caused the first cities of Mesopotamia to appear? Was it trade links, was it agricultural surplus, was it exporting high quality goods or was it religion? Maybe it was all of them.

Bowl from EriduThis has been a difficult post to write. When I started writing had an idea of what I was trying to say. Now, having finished, the result is not what I intended. Regardless, here it is, for better or worse.

In the south of Iraq, often referred to as southern Mesopotamia, the parallel courses of the mighty Tigris and Euphrates Rivers roughly define a strip of fertile but difficult alluvial soil. On either side of this alluvial strip the land is semi-desert.

The mother of all fertile plains

Before they were dammed both the Tigris and Euphrates were liable to considerable variation in flow rates. Water levels reached a peak between March and May when spring’s rising temperatures caused the snows of the Taurus mountains in the north to melt. This usually resulted in flooding of the plain. The extent of this flooding varied considerably from year to year. As summer turned to winter the water levels dropped steadily until the next spring thaw started the cycle again.

All this made agriculture very challenging here. During the autumn sowing season the dry earth had to be irrigated by the feeble flow of the rivers to moisten the soil and make it possible just to turn it over, ready for the seed.

Conversely in spring, just when farmers were preparing to harvest, floods were likely to wash away their crop. The flood waters at this time therefore needed to be carefully channelled off to places where they wouldn’t do too much damage. But the rewards for mastering these techniques were great. The harvests supplied by the rivers could be bountiful.

The archaeological evidence

Despite the rise of farming around the fertile crescent from the ninth millennium BC, it was not until the middle of the sixth millennium BC, in what’s now known as the ‘Ubaid period, that a series of small settlements started to appear along the river banks of the southern Euphrates. Each of these settlements seems to have contained a small temple at its centre.

The ‘Ubaid culture’s influence must eventually have been extensive, as decorated but mediocre late ‘Ubaid pottery is found from the Zagros mountains in the north to the coasts along the Persian/Arabian Gulf to the south. Most of this seems to have been made in the settlements along the southern Euphrates.

Around the latter part of the fifth millennium BC (the Uruk Period) some of the Euphrates settlements expanded to form cities, probably with leaders. Uruk, Eridu, Ur and others each became the focus of life and activity for tens of thousands of people.

Luxury goods also start to appear at this time. These cities had become the largest settlements in the world. And at the centre of each city stood a great temple, the descendant of the little ‘Ubaid Period temple, dedicated to some particular local god or goddess.

But why did the ‘Ubaid cultures of southern Mesopotamia come into existence and why did they evolve into the world’s first cities?

The agricultural surplus model

If you read most books about the origins of ancient Mesopotamian cities you will tend to get some variation of the following.

Locals/migrants from the mountains to the north settled southern Mesopotamia during the ‘Ubaid Period. Collective action, perhaps under the guidance of great leaders, led to the draining of swamps and cutting of ditches in extensive irrigation schemes to make the swamps tillable and the deserts fertile. The rich alluvial soils between the rivers soon produced bountiful harvests for relatively low effort.

This led to a surplus of farm produce. By the Uruk period this produce had brought wealth to the river valley settlements because it was used to purchase much needed raw materials and to feed a developing artisan class and civil service. So the settlements grew into rich cities, importing luxury items.

The major idea of this model, following the economic theories of Adam Smith, is that it is the abundance of the fertile soil, made available by collective action, that created the wealth of the cities.

But a problem with this seems to be that it implies some kind of organising leader even before there is a state to rule. Furthermore, I find it difficult to believe that the export of surplus agricultural produce is enough to create huge wealth on its own.

In my efforts to explore the primary role of trade in the growth of early farming and civilisation, I might have initially guessed at a very different story.

The trade model

Due to improved transport and/or new trade goods appearing, the southern Euphrates river became a small but significant trade route during the ‘Ubaid period for traders travelling the routes between the Arabian/Persian Gulf in the south and the Zagros/Taurus mountains to the north. Individuals established themselves in settlements at important points along this route to act as ‘service stations’, providing food for the travellers in return for raw materials.

An increase in the number of traders along the Euphrates during Uruk times required an increase in production of agricultural surplus. This could be easily accommodated by increasing agricultural production, something which was possible with large-scale irrigation and organisation. Settlements expanded to supply the needs of traders. Given time, the settlements expanded into cities and took control of the trade routes themselves.

The major idea of this model is an individualist one, that everyone is simply there to get rich and that some people do this by controlling the trade routes. However, there are many problems with this idea.

Firstly, whilst greed is certainly a major driving force in most societies, it is not everything. Second, the communal effort initially required to make the dry alluvial soils and swamps fertile back in the Ubaid period cannot really be explained by individual settlement. Irrigation is a major undertaking.

Trying to find a better model

Bearing in mind the points made, one thing that seems to be left out in both models is one of the important bases for many modern economies, adding value to goods. For example, modern China imports raw materials, such as metal, and also exports food, just as ancient Mesopotamian cities are thought to have done.

However China also exports improved goods, such as electronic devices, which are made from the raw materials it imports. This is perhaps the major reason for China’s success. This depends on having a skilled workforce, the modern equivalents of Mesopotamian artisans.

Secondly, what about those temples? What is the significance of them. This suggests a considerable religious aspect to the life of both settlements and cities.

This is perhaps where a more modern analogy may help.

Salt Lake City

Salt Lake City, sited near the Great Salt Lake in northern Utah, sits to the south of the main California Trail, one of the great east west routes across North America during the eighteenth and nineteenth centuries. The area had seen people come and go before, both nomadic native Americans and Europeans crossing the continent toward California, but none had thought to settle there permanently until 1847.

The story goes that Brigham Young and his small band of less than two hundred Mormons (members of the Church of Jesus Christ of Latter-day saints) chose to settle there under God’s guidance after being hounded out of Illinois for their unusual religious beliefs.

Because Salt Lake Valley is arid the people of this difficult new settlement worked closely together. Under Young and his council’s leadership they irrigated and worked the land around the Jordan River to make it fertile.

The first couple of years were tough and the settlement nearly failed. However with luck it soon expanded to almost two thousand with the influx of new settlers. Many were Mormon but many of them were not.

What sealed the success of the settlement was the gold rush, starting in 1848. Tens of thousands of people from the eastern states went west to California past Salt Lake City. Many returned. All needed provisions. On the way out they brought tradeable goods and money from the east. On the way back some of them brought gold. To this day Salt Lake City is proud of its commercial as well as its religious heritage.

The settlement boomed. With its growth the foundations for a Mormon temple were laid at the centre of the site in 1853. To this day the resulting temple is the major landmark of the city and Salt Lake City is the centre of the Mormon religion. By the time of the temple’s completion in 1892 the railroad had come to Salt Lake City and city’s population was around forty thousand. The greater urban area of Salt Lake City now includes over a million people.

Is this a good comparison?

Partly. Firstly, things were different in the past and any development would not involve fleeing from some pre-existing state because there probably wasn’t one. Also the success of Salt Lake City was almost instant, due in large part to the California Gold Rush but soon helped by the arrival of the railroad.

However, what Salt Lake City highlights to me is the possibility of a religious foundation for the cities of southern Mesopotamia. People must have needed some particular motivation to come to such a harsh place to and start farming. I assumed that this would be commercial greed but this is probably wrong.

Perhaps the settlers’ main motivation was to establish a religious community in the wilderness. The fact that it lay on an existing route through the landscape, and indeed one by a river, is hardly surprising. The fact that the more faint-hearted might not have taken up farming there is equally unsurprising.

Getting lucky

The success of such a religious foundation is not guaranteed. You only have to look at the isolated ruins of monasteries in Wales or of the Dead Sea settlement at Qumran to realise that. What must underlie the success of the settlements in Mesopotamia are two things. First that the soil was good when you tamed it. Second that the settlements lay either on trade routes or at the ends of easy routes for import and export of goods.

This introduces a much more random element to the settlement of new areas. People may try to settle anywhere beyond the existing zone of agricultural settlement, and often not for reasons of greed. There may be simple reasons, such as lack of work or food, or complex reasons, such as religious persecution or a wish to be away from ‘normal’ society.

But those settlements will only be successful if they are located in the right places. Salt Lake City was a religious settlement but it was also in the right place. This was in large part because it lay on the routes to California during the Gold Rush. Perhaps the ‘Ubaid period settlers of southern Iraq also got lucky.

So using what I’ve got…

A third model

Religious groups, migrating along existing routes through Iraq, settled the banks of the southern Euphrates River in the ‘Ubaid period. Through communal effort they successfully irrigated and farmed the alluvial soils.

Occasional surplus produce was exchanged for useful raw materials with the few traders journeying along the river between the Zagros/Taurus Mountains in the north and the Arabian/Persian Gulf in the south. The usefulness of this exchange was recognised by the settlers. They increased the farming surplus in order to exchange it with passing traders. This encouraged more traders to use the route.

With increasing organisation settlements expanded their agriculture to supply food to this expanding trade. They also started to supply pottery, possibly used by traders for carrying food, for ballast and for exchange with people on the Persian/Arabian Gulf to the south and, to a lesser extent with people to the north.

By Uruk times settlements were growing enough agricultural produce to support an artisan class (possibly immigrants). Luxury raw materials were imported and crafted into goods for export, rapidly increasing the wealth of the settlements which expanded into cities. Cities probably took control of trade and trade routes by force at this time.

In the end there’s nothing particularly radical about what I’ve concluded. Admittedly it doesn’t mention leaders, although I’m sure they were there. Of course there may also have been external factors in the development of cities during Uruk times, such as the availability of new materials (such as pearls, copper, precious stone etc), improved transport or the extension of trade routes.

It’s also worth asking whether there was something about the communal, possiblty religious nature of the settlements’ inhabitants that made them better suited to creating these first cities. Frankly, it’s difficult to say after all this time.

Regardless, if this model gives some approximation to truth then it would mean that I have been wrong. Trade would not have been the primary reason why people farmed the banks of the Euphrates River. However, like evolutionary advantage, those who settled in the right place to trade, even if that trade was limited, would be end up being the winners.

Only subsequently did the two rivers split due to spread on an alluvial fan. It is essential to understand this to understand how Uruk could have been so essential to the development of cities. Any other situation would not have produced the spectacular rise of Uruk. Ironically, it also means that there was no such thing as “Mesopotamia” at the time.

Good stuff here. Helps make you think about how we have gotten where we are.

Yeah agricultural surplus allows the scam of usury/interest to exist in the first place. The central bank based world money system cannot continue because its fundamentally flawed. So we need to stop using it.

Find or found local exchange systems and start using them. Any little things you can do to cut banking system money out of your life will lead to global social improvements. This is the first time in humanity that we’ve been faced with problems of this scale but fortunately we’ve also built the infrastructure to solve them (internet and information sharing) now. So we must hop to it!

Dear ‘Blade’

I have a feeling that I might (at least partly) disagree with you here. It’s not that I don’t hold socialist ideals of a fairer world, its just that I’m coming to think (disturbingly for me) that the world doesn’t work only like that and, indeed, that some form of banking has been crucial to both the good and the bad of our world. That includes the infrastructure of the internet and information sharing. I don’t know where you are, but the fact that I’m replying to you has a lot to do with banks lending money to small businesses so that they could develop the electronics that I’m typing this on. However, if you wish to criticise banks for their dangerous behaviour over the last twenty years then that’s another matter…

Whatever, with the infrastructure in place there’s a chance to influence the world for the better.

How about banking? Closely associated with religion, for instance Jews and the Templar financing of travel to the Holy Land. Didn’t some of those Mesopotamians have deposit receipts in the form of little clay models (in stamped ‘envelopes’) of goods deposited? Great opportunity for invention of credit and fractional reserve banking. How about getting rich through invention and control of the money supply? Nothing new under the sun.

Dear Raven

Certainly there are forms of lending attested around the second millennium BC and possibly a little earlier. However, this is all a little later. Some evidence of methods of making contracts, such as cylinder seals, as well as clay tokens, which may represent goods, do exist during ‘Ubaid times. However using money is probably anachronistic, as this doesn’t seem to appear until the first millennium BC.

Actually, thinking about it you’re probably right. Lending and borrowing (anthropology’s ‘reciprocal exchange’), but with interest, probably underlies the expansion of society during Uruk times (and possibly earlier) as this kind of win-win interaction is the basis of all modern economics. But this economics must be underpinned by agriculture, as it is even now, otherwise it doesn’t work. Whether this ‘banking’ was run by individuals, corporations, priests or kings I can only guess.
