The processes in which they emerged are touched on in some of the earliest literary sources for Indian history, the
The later Vedic texts and the general richness of the Aryan literary record make it all too easy to forget the existence of half the subcontinent. Written evidence tends to confine Indian history down to this point (and even after) to the history of the north. The state of archaeological and historical scholarship also reflects and further explains the concentration of attention on northern India. There is just much more known about it in ancient times than about the south. But there are also better and less accidental justifications for such an emphasis. The archaeological evidence shows, for example, a clear and continuing cultural lag in this early period between the area of the Indus system and the rest of India (to which, it may be remarked, the river was to give its name). Enlightenment (if it may be so expressed) came from the north. In the south, near modern Mysore, settlements roughly contemporaneous with Harappa show no trace of metal, though there is evidence of domesticated cattle and goats. Bronze and copper only begin to appear at some time after the Aryan arrival in the north. Once outside the Indus system, too, there are no contemporary metal sculptures, no seals and fewer terracotta figures. In Kashmir and eastern Bengal there are strong evidences of Stone Age cultures with affinities with those of south China, but it is at least clear that, whatever the local characteristics of the Indian cultures with which they were in contact and within the limits imposed by geography, first Harappan and then Aryan civilization were dominant. They gradually asserted themselves towards Bengal and the Ganges valley, down the west coast towards Gujarat, and in the central highlands of the subcontinent. This is the pattern of the Dark Ages, and when we reach that of history, there is not much additional light. The survival of Dravidian languages in the south shows the region’s persistent isolation.
Topography explains much of it. The Deccan has always been cut off from the north by jungle-clad mountains, the Vindhya. Internally, too, the south is broken and hilly, and this did not favour the building of large states as did the open plains of the north. Instead, south India remained fragmented, some of its peoples persisting, thanks to their inaccessibility, in the hunting and gathering cultures of a tribal age. Others, by a different accident of geography, turned to the seas – another contrast with the predominantly agrarian empires of the north.
Millions of people must have been affected by the changes so far described. Estimates of ancient populations are notoriously unreliable. India’s has been put at about 25 million in 400 BC, which would be roughly a quarter of the whole population of the world at that time. The importance of India’s early history nevertheless lies in the way it laid down patterns still shaping the lives of even larger numbers today, rather than in its impact on big populations in antiquity. This is above all true of religion. Classical Hinduism crystallized in the first millennium BC. As it did, India also gave birth to the first world religion – Buddhism; it was eventually to dominate wide areas of Asia. What men do is shaped by what they believe they can do; it is the making of a culture that is the pulse of Indian history, not the making of a nation or an economy, and to this culture religion was central.
