The Classical Civilizations of Eurasia

The earliest civilizations arose at a few scattered points in the vast and sparsely inhabited Eurasian landmass. Between 1000 BC and 500 AD the pattern began to change. Although America, Australasia and Africa south of the Sahara still stood outside the mainstream of world history, and were to stay so for a further thousand years, the civilizations of Europe and Asia now formed a continuous belt. By 100 AD, when the classical era was at its height, a chain of empires extended from Rome via Parthia and the Kushana empire to China, constituting an unbroken zone of civilized life from the Atlantic to the Pacific.

This was a new and important fact in the history of the Eurasian world. The area of civilization remained narrow and exposed to unrelenting barbarian pressures, and developments in the different regions remained largely autonomous. But with the expansion of the major civilizations and the elimination of the geographical gaps between them, the way lay open for inter-regional contacts and cultural exchanges which left a lasting imprint. In the west, the expansion of Hellenism created a single cultural area which extended from the frontiers of India to Britain; in the east, the expansion of the Chinese and Indian civilizations resulted in a kind of cultural symbiosis in Indo-China. These wider cultural areas provided a vehicle not only for trade but for the transmission of ideas, technology and institutions, and above all for the diffusion of the great world religions. Beginning with Buddhism, and continuing with Judaism, Zoroastrianism, Christianity and Islam, religion became a powerful unifying bond in the Eurasian world.
