THE STORY OF HUMANITY

CHAPTER 0 — BEFORE HISTORY

For thousands of years, human beings lived in relatively small communities. They hunted animals, gathered plants, cultivated crops, raised animals and moved through landscapes according to the availability of food and water. Gradually, some communities began to remain in particular places for longer periods. Villages became larger, populations increased and people began developing specialized skills. Eventually, some settlements grew so large and complex that they became something fundamentally different from a village. They became cities. The emergence of cities was one of the most important transformations in human history because it changed not only where people lived, but also how they worked, traded, governed themselves and interacted with one another.

The first cities did not appear suddenly, and there was no single place where humanity invented the idea of a city. Urban societies developed independently in different parts of the world and at different times. However, many of the earliest complex societies developed around major rivers. This was not simply because rivers provided drinking water. Rivers could provide fertile land for agriculture, support irrigation, offer transportation routes and connect communities over considerable distances. At the same time, rivers could be unpredictable and dangerous. Floods could destroy crops, settlements and infrastructure, meaning that communities had to develop ways of managing water. The ability to organize large numbers of people around these challenges became increasingly important as settlements grew.

One of the earliest and most influential urban regions developed in Mesopotamia, the land between the Tigris and Euphrates rivers. Much of ancient Mesopotamia corresponds to parts of modern-day Iraq and surrounding regions. The environment presented both opportunities and difficulties. Agriculture could be highly productive, but in many areas reliable farming depended on controlling and distributing water. Communities developed irrigation systems that brought water to agricultural fields. Canals had to be constructed, maintained and repaired. Farmers had to coordinate their activities, and the products of agriculture had to be collected, stored and distributed. These requirements encouraged increasingly complex forms of organization.

Among the most important early urban settlements was Uruk in southern Mesopotamia. By the fourth millennium BCE, Uruk had grown into a remarkably large and complex settlement for its time. It contained monumental buildings, specialized craft production, administrative institutions and evidence of extensive economic activity. It was not simply a large village. People living in and around Uruk were participating in a system that connected farmers, craftspeople, labourers, administrators, religious institutions and political authorities. Food came into the settlement from the surrounding countryside, while manufactured goods, administration and other forms of specialized activity became concentrated within the urban centre.

The growth of cities changed the nature of human work. In a small agricultural settlement, most people would have been directly involved in obtaining or producing food. As agricultural production increased, however, some people could devote more of their time to other occupations. A person could become a potter, metalworker, builder, trader, weaver or administrator. Others could specialize in religious activities or military organization. This process of specialization was one of the foundations of urban society because it allowed people to develop skills that would have been difficult to maintain if everyone had to spend most of their time producing food.

The relationship between the city and the countryside became particularly important. Cities depended on surrounding agricultural communities for food, fuel and raw materials. The countryside, in turn, could benefit from access to urban markets and specialized goods. This relationship was not always equal. As cities became centres of political and economic power, those who controlled institutions within them could gain influence over land, labour and food. Differences in wealth and status became more visible, and societies developed increasingly complex hierarchies. Civilization therefore brought new opportunities for cooperation and specialization, but it also created new forms of inequality.

Religion was closely connected to the development of many early cities. In Mesopotamia, temples dedicated to different deities were important institutions within urban communities. They were places of worship, but their role could extend far beyond religious ceremonies. Temples could own land, employ workers, receive agricultural products and participate in the administration of resources. Religious and economic life were therefore deeply connected. The distinction between religion, government and economy that is familiar in many modern societies did not necessarily exist in the same form in early urban civilizations.

As cities became larger, another problem emerged. There was simply too much information for individuals to remember. A small community could rely heavily on personal knowledge and oral communication, but a large urban institution might need to keep track of enormous quantities of grain, animals, tools and other goods. Administrators needed to know what had been received, what had been distributed and what remained. They needed ways to keep track of workers and transactions. The solution was one of humanity's most important inventions: writing.

In Mesopotamia, early writing developed during the late fourth millennium BCE, initially for administrative purposes. People began making marks on clay tablets to record quantities and transactions. Over time, these systems developed into cuneiform writing. What began as a practical method of keeping records eventually became capable of recording much more. Laws, letters, religious texts, stories and other forms of information could be preserved. Writing created a new kind of human memory because information could now exist outside the minds of individuals and be transmitted across generations.

The importance of this development cannot be overstated. Before writing, human societies relied heavily on memory, oral traditions and physical demonstrations to preserve knowledge. A story could be remembered and retold, a craft could be taught to an apprentice and a tradition could be passed from parents to children. But written records introduced a new possibility. A message could be stored in physical form and read by someone who had never met its original author. An agreement could be recorded. A quantity of grain could be documented. A ruler's instructions could be preserved. A legal decision could survive the people who originally made it.

The development of writing also gives historians something that earlier periods largely lack: direct written evidence from the people who lived in those societies. Before writing, researchers have to reconstruct human life primarily through archaeology, environmental evidence, human remains, tools and other physical traces. Once writing appears, ancient people begin leaving behind their own records. These records are not complete and they often reflect the perspectives of rulers, administrators or institutions rather than ordinary people, but they provide an extraordinary window into ancient society.

As cities expanded, formal systems of law and administration also became increasingly important. People living in large communities could not always rely on personal relationships to settle disputes. Questions about property, trade, labour, debt and family relationships required mechanisms for resolving disagreements. Different Mesopotamian societies developed their own legal traditions. One of the most famous surviving examples is the collection of laws associated with the Babylonian king Hammurabi in the eighteenth century BCE. The Code of Hammurabi was not the first law code in history, but it provides important evidence of how a powerful state attempted to regulate aspects of society through written rules.

The growth of cities also created competition. Mesopotamia was not a single unified country during its early urban development. It contained numerous city-states, including Uruk, Ur, Lagash, Kish and others. These cities traded with one another, interacted politically and sometimes fought wars. Each could have its own ruler, institutions and religious traditions. Competition over land, water, trade routes and political influence could lead to conflict. Warfare itself was not new, but cities and states provided new organizational structures through which larger numbers of people and resources could be mobilized.

This was one of the contradictions of early civilization. Cities required cooperation on a scale that earlier communities had rarely experienced, yet they also created new opportunities for conflict. Thousands of people had to work together to construct buildings, produce food, maintain infrastructure and operate institutions. At the same time, rulers could use the resources of cities to build armies and expand their territories. Civilization increased both the capacity for cooperation and the capacity for organized conflict.

Mesopotamia was not the only place where complex societies were emerging. Around the same broad period, other regions of the world were undergoing their own transformations. Along the Nile, communities that would eventually form ancient Egypt were becoming increasingly interconnected. Far to the east, complex societies were developing in South Asia around the Indus and its associated river systems. In China, communities along major rivers were developing increasingly sophisticated agricultural and political systems. These societies did not all follow the same path, and they did not necessarily depend upon one another for their basic development. Their histories demonstrate that human communities in different environments could independently develop complex solutions to similar problems.

One of the most important questions faced by all of these societies was how to feed a growing population. A city could not exist without a reliable supply of food. Most of the people living in an urban centre could not spend all of their time farming, so the surrounding countryside had to produce enough surplus to support specialists, administrators, craftspeople, religious institutions and political authorities. This created a relationship between urban and rural communities that would remain fundamental throughout much of human history.

The emergence of cities also transformed the physical landscape. Agricultural land expanded, forests were cleared, irrigation channels were constructed and settlements became increasingly permanent. Human beings were no longer simply adapting to natural environments. They were actively reshaping them. This process began on a relatively small scale compared with the modern world, but it established a pattern that would continue for thousands of years. As populations and technologies grew, humanity's ability to transform landscapes would become increasingly powerful.

Yet it is important to remember that the first cities were not simply collections of impressive buildings. They were places where ordinary people lived their lives. Children were born there and grew up there. Families prepared food, workers produced goods, traders negotiated exchanges and craftspeople spent long hours making objects by hand. People formed friendships, argued with their neighbours, fell in love, suffered illnesses and mourned their dead. The monumental structures that survive today can make ancient cities appear distant and mysterious, but behind those structures were communities of human beings whose daily lives were surprisingly familiar in many ways.

The people who built the first cities also could not have understood the full consequences of what they were doing. The farmers who produced surplus grain were not trying to create an urban civilization. The administrators keeping records on clay tablets were not trying to invent a technology that would eventually become the foundation of written literature and recorded history. The craftspeople producing tools and pottery were not imagining future industrial societies. Each generation was solving the problems immediately in front of it, while the combined effect of those solutions was gradually transforming human society.

This is one of the central themes of history. Major transformations are often created by countless smaller decisions made by people who cannot see where those decisions will eventually lead. The first farmers could not imagine cities. The first city builders could not imagine empires. The first writers could not imagine libraries containing millions of books. Yet each development created possibilities for the next.

The rise of cities therefore represented a major turning point in the story of humanity. For the first time, large numbers of people could live together in permanent settlements with specialized occupations, organized administration, religious institutions, systems of law and written records. Human society had become complex enough to support political structures that extended beyond individual communities.

The city would become the foundation for the next stage of the story.

Cities would produce rulers, kingdoms and eventually empires. Trade networks would connect distant regions. Writing would preserve laws, stories and ideas. Engineers would build monumental structures. Armies would conquer territories. Religious traditions would spread across borders. And different civilizations would encounter one another, sometimes peacefully through trade and cultural exchange, and sometimes violently through war and conquest.

But before those great empires appeared, another civilization was taking shape along one of the world's great rivers.

The Nile.

Every year, the river transformed the landscape of northeastern Africa. Its waters made agriculture possible across a region surrounded by desert. Communities living along the river became increasingly connected, and over time, political power began to consolidate. Eventually, Upper and Lower Egypt would be united under a single kingdom.

The result would be one of the most recognizable civilizations in human history.

Its rulers would be called pharaohs.

Its scribes would develop one of the world's most famous writing systems.

Its engineers would construct monuments that still dominate our imagination thousands of years later.

And its civilization would endure for an extraordinary length of time.

But Egypt was not the only great civilization developing in the ancient world. Far to the east, across the lands of the Indus, another urban society was emerging with carefully planned settlements, sophisticated drainage systems and a distinctive culture whose written language remains largely undeciphered.

The human story was becoming bigger.

There was no longer a single small world of scattered communities.

There were now cities, regions and civilizations.

And they were beginning to connect.
