Cradles of Civilization (c. 3200BC - c. 500AD)

The Bronze Age is part of the three-age system (Stone Age, Bronze Age, Iron Age) that for some parts of the world describes effectively the early history of civilization. During this era the most fertile areas of the world saw city states and the first civilizations develop. These were concentrated in fertile river valleys: the Tigris and Euphrates in Mesopotamia, the Nile in Egypt, the Indus in the Indian subcontinent, and the Yangtze and Yellow River in China.

Sumer, located in Mesopotamia, is the first known complex civilization, developing the first city-states in the 4th millennium BCE. It was in these cities that the earliest known form of writing, cuneiform script, appeared c. 3000 BCE. Cuneiform writing began as a system of pictographs. These pictorial representations eventually became simplified and more abstract. Cuneiform texts were written on clay tablets, on which symbols were drawn with a blunt reed used as a stylus. Writing made the administration of a large state far easier.

Transport was facilitated by waterways—by rivers and seas. The Mediterranean Sea, at the juncture of three continents, fostered the projection of military power and the exchange of goods, ideas and inventions. This era also saw new land technologies, such as horse-based cavalry and chariots, that allowed armies to move faster.

These developments led to the rise of empires. Such extensive civilizations brought peace and stability over wider areas. The first empire, controlling a large territory and many cities, developed in Egypt with the unification of Lower and Upper Egypt c. 3100 BCE, while in Crete the Minoan Civilization had started to flourish at 2700 BCE and is regarded as the first civilization in Europe. Over the next millennia, other river valleys would see monarchical empires rise to power. In the 25th century and 24th century BCE, Assyria and the Akkadian Empire, respectively, arose in Mesopotamia; and c. 2200 BCE the Xia Dynasty arose in China.

Over the following millennia, civilizations would develop across the world. Trade would increasingly become a source of power as states with access to important resources or controlling important trade routes would rise to dominance. In c. 2500 BCE, the Kingdom of Kerma developed in Sudan, south of Egypt. In modern Turkey the Hittites controlled a large empire and by 1600 BCE, Mycenaean Greece began to develop. In India this era was the Vedic period, which laid the foundations of Hinduism and other cultural aspects of early Indian society, and ended in the 6th century BCE. From around 550 BCE, many independent kingdoms and republics known as the Mahajanapadas were established across the subcontinent.

As complex civilizations arose in the Eastern Hemisphere, most indigenous societies in the Americas remained relatively simple for some time, fragmented into diverse regional cultures. During the Formative stage in Mesoamerica, (about 1500 BCE to 500 CE), more complex and centralized civilizations began to develop, mostly in what is now Mexico, Central America, and Peru. They include civilizations such as the Olmec, Maya, Zapotec, Moche, and Nazca. They developed agriculture as well, growing maize and other crops unique to the Americas, and creating a distinct culture and religion. These ancient indigenous societies would be greatly affected by European contact during the early modern period.
