ISLAND RESOURCES
Between AD 750 and 1300, a multitude of largely independent cultures evolved on these little “island universes”. In the New Guinea highlands, where farming flourished, population density was the greatest in the world and easily sustainable. On most Pacific islands a balance was reached between population and natural resources; in less hospitable places, such as Easter Island and New Zealand, initially abundant resources became very depleted and, by the time of European contact in the 17th and 18th centuries, populations were in conflict and decline. When the Maoris arrived in Aotearoa (New Zealand) from about AD 750, they found large numbers of a flightless bird, the Moa. Some of these were gigantic, up to 3m (10ft) high and weighing up to 250kg (550lb). Unafraid of man, the Moa proved a readily available food source, and over the next 400 years they were hunted to extinction. The first Maoris thus established themselves with a Moa-fed burst in population numbers, while succeeding generations had to battle hard to sustain themselves.
About 6000 years ago, in a few areas of particularly intensive agriculture, the dispersed villages of Neolithic peoples gave way to more complex societies. These were the first civilizations, and their emergence marks the start of a new phase of world history. They arose, apparently independently, in four widely dispersed areas (the early civilizations of America emerged considerably later): the lower Tigris and Euphrates valleys; the valley of the Nile; the Indus valley around Harrappa and Mohenjo-Daro; and the Yellow River around An-yang. The characteristic feature of them all was the city, which now became an increasingly dominant social form, gradually encroaching on the surrounding countryside, until today urban civilization has become the criterion of social progress. But the city possessed other important connotations: a complex division of labour; literacy and a literate class (usually the priesthood); monumental public buildings; political and religious hierarchies; a kingship descended from the gods; and ultimately empire, or the claim to universal rule. A dichotomy already existed between the civilized world and the barbarian world outside. The onslaught of nomadic peoples eager to enjoy the fruits of civilization became a recurrent theme of world history until the advent of effective firearms in the 15th century AD tilted the balance in favour of the civilized peoples.

THE BEGINNINGS OF CIVILIZATION IN THE EURASIAN WORLD
Urban civilizations developed independently in four different areas of Eurasia, as the exploitation of fertile river valleys allowed complex forms of social organization. The sudden growth of cities was a dramatic development in human history, and was accompanied by the beginnings of literacy. From this period it becomes possible to write true history.
The development of urban societies seems to have been triggered by a sudden concentration of population in certain river valleys, which in some cases may have been a result of climate change which made the surrounding areas outside the valleys less attractive for habitation. The need to exploit the fertile land of these valleys and their alluvial plains to feed a growing population then led to the development of irrigation and flood-control mechanisms. In Mesopotamia and China this involved the construction of canals to carry water away to the land around the Tigris-Euphrates and the Yellow River, while in Egypt and India the annual flooding of the Nile and Indus provided fertile silt in which crops were grown.
THE FIRST CITIES
The concentrated populations were able to produce surplus crops which could be exported to areas beyond the rivers in return for raw materials and precious items not locally available, above all bronze. The food surplus also made possible social groups not directly involved in agriculture, whether specialized craftsmen or rulers and military leaders. It was when ambitious individuals and families succeeded in diverting resources into the construction of monumental ceremonial centres that provided a focus for the populations living near them that the first true cities appeared. This took place in Mesopotamia in c. 3500 BC and in Egypt in c. 3100 BC, while the Indus valley cities appeared in c. 2500 BC, and in China urbanism began in c. 1800 BC.
The political development of these different regions was not uniform: in Egypt a single unified kingdom emerged almost immediately, extending from the Nile delta south to the first cataract; in China the earliest civilization is associated with the Shang dynasty, although the Shang rulers may have just been leaders of a loose confederacy. In Mesopotamia, by contrast, no one city was able to establish control for any period, and competition for dominance between the leading cities characterized the history of the area for nearly three millennia. The situation in the Indus valley is less clear, but the major cities of Harappa and Mohenjo-Daro appear to have coexisted until the decline of the Indus cities after about 2000 BC. It appears that in all these civilizations, religious, political and military power was concentrated in the hands of a few ruling families.
Trade and exchange were important in the expansion of the first civilizations. The possession of prestige goods and the desire to acquire more resources were instrumental in the emergence of the first empires in Mesopotamia. During the 3rd millennium BC goods were being traded between the Indus and the Mediterranean. In the 2nd millennium BC urbanization spread to Anatolia and the Aegean, and the cultural influence of the Near East can be seen in the bronze-working of the Balkan communities. However, in many parts of Eurasia, including the fertile river deltas of the Ganges and Mekong, the landscape did not favour concentrations of population, and village communities remained the norm until the 1st millennium BC.
The development of writing occurred almost at the start of each of the four civilizations. The earliest known use of writing in China was for divination: the Shang rulers used prepared turtle shells and ox scapulae heated in a fire to establish the will of the gods, and the result of the enquiry was scratched onto the shell or bone. In Mesopotamia, Egypt and the Indus valley writing was used mainly for administrative activities, with inventories and accounts being inscribed on clay. Early examples of writing have often survived because clay tablets were accidentally baked, fixing the messages permanently. Clay inscriptions spread to Crete and Greece by around 1500 BC. In Egypt and Mesopotamia the use of writing developed rapidly, as large public inscriptions, including law-codes, were erected by the rulers as monuments to their wisdom, justice and power. It is from monuments such as these, celebrating their victories or their public works, that the earliest true history can be reconstructed.

THE EARLY EMPIRES OF
MESOPOTAMIA
The broad plain through which the Tigris and Euphrates rivers flow gave birth to the world’s first cities. Irrigation systems made it possible to support substantial populations and complex administrative structures. With urbanization came more developed economies and trade, while competition between cities led to warfare and the first empires.
The earliest cities appeared in Mesopotamia in the second half of the 4th millennium BC: at Uruk, Ur, Tell ‘Uqair and Susa vast and elaborately decorated ceremonial complexes were built as the centres of urban settlements, probably under the leadership of families eager to display their power and their respect for the gods. The fertile plains and valleys watered by the Tigris and the Euphrates produced food surpluses sufficient to support these elaborate new centres and their complex social structures.
The cities were the basic political units of Mesopotamia. Religion was fundamental to their social organization: the rulers of cities presented themselves as favoured servants of the gods, while lower down the social scale agricultural workers had a necessary role in producing the materials for sacrifices and offerings to the gods. The cities established diplomatic and trade relationships with each other, although little is known of the mechanisms for this. Finds of goods from Uruk, the predominant city in Mespotamia from around 3500 BC, have come from as far afield as Susa and Syria. The effect of trade and gift-exchange
