diverse. But surprisingly, considering Braudel’s emphasis on environments, he ignores a more obvious explanation. Settlement was not uniform and integration not easily achieved because what geography had so obligingly joined together, hydrography put asunder.
India enjoys tropical temperatures, yet during most of the year over most of the country there is no rain. Growth therefore depends on short seasonal precipitations, as epitomised by the south-west monsoon which sweeps unevenly across nearly the whole country between June and September. The pattern of rainfall, and the extent to which particular landscapes can benefit from it by slowing and conserving its run-off, were the decisive factors in determining patterns of settlement. Where water was readily available for longest, there agriculture could prosper, populations grow, and societies develop. Where not, stubby fingers of scrub, broad belts of desert and bulging plateaux of rock obtruded, cutting off the favoured areas of settlement one from the other.
Like lakes, long rivers with little fall, especially if their flood is prolonged by snow-melt as with the Ganga and the Indus, serve the purpose of conserving water well. Much of northern India relies on its rivers, although the lands they best serve, as also their braided courses and even their number, have changed over the centuries. Depending on one’s chosen date, Indian history begins somewhere on the banks of north India’s litany of great rivers – either along the lower Indus or amongst the ‘five rivers’ (panj-ab, hence Panjab, or Punjab) which are its tributaries, or in the ‘two rivers’ (do-ab, hence Doab) region between the Jamuna (Jumna) and the Ganga, or along the middle Ganga in eastern Uttar Pradesh and Bihar.
North India’s mighty river systems ordained much the most extensive of these well-watered zones of agricultural settlement; and though these zones were several, in the course of the first millennium BC they tended to become contiguous, thus creating a corridor of patchy cultivation and settlement from the north-west in what is now Pakistan to Bihar in the east. Here commercial exchange, cultural uniformity and political rivalry got off to an early start. The corridor became a broad swathe of competing states, cherishing similar ideals, revering common traditions and inviting claims of paramountcy. For empire-builders like the Mauryas, Guptas and Vardhanas, this was where the idea of Indian dominion began.
Elsewhere surface reservoirs supplemented rivers as a useful means of water conservation if the terrain permitted. In the deep south, weeks after Tamil Nadu’s November rains have ceased, what looks from the air like chronic flooding proves to be a cunningly designed patchwork of fields with their sides so embanked as to form reservoirs, or ‘tanks’. When, after carefully managed use and the inevitable evaporation, the water is nearly exhausted, the tank can itself be planted with a late rice crop. Since the peninsula lacks the vast alluvial plains of the north and has to accommodate hills like the Western Ghats, zones favourable to agricultural settlement were here smaller although numerous and, in cases like the Kerala coast, exceptionally well watered.
In other regions geology did its best for moisture conservation by trapping water underground. From wells it could then be laboriously hauled to the surface for limited irrigation. For the intervening zones of greatest aridity, this sub-surface water was the only source available during most of the year. And since about half the subcontinent receives less than eighty centimetres of rain per year, these arid zones were large. By supposing a continuity between the western deserts of Sind/Rajasthan and the drier parts of central India plus the great Deccan plateau of the peninsula, a broad north – south divide has sometimes been inferred. In fact the terminology here is too vague (even the Deccan is more a designation of convenience than a natural feature). Moreover, considerable rivers traverse this divide: the Chambal and Betwa, tributaries of the Jamuna, afford north – south corridors between the Gangetic plain and the peninsula. And slicing across the waist of India, the west-flowing Narmada forms a much more obvious north – south divide; indeed it figures historically as something of an Indian Rubicon between the north and the peninsula. Micro-zones with excellent water conservation also dot both Rajasthan and the Deccan; in historical times they would sustain a succession of the most formidable dynasties.
As with the forests and wetlands, the dry-lands were not without their own sparser populations, typically herdsmen and warriors. As barriers, dry regions are hardly as formidable as the seas and mountains of Europe. But as boundaries and frontier zones they did have something of the same effect, encouraging separation, fostering distinction and, in time, confronting ambitious rulers with the great Indian paradox of a land that invited dominion full of lesser rulers who felt bound to resist it.
The socio-cultural dimension to this climate-induced paradox would be even more enduring. Indeed it largely accounts for the strength of ‘regional’ sentiment in the subcontinent today. In those favoured, because well-watered, zones where settlement became concentrated, surplus agricultural production encouraged the development of non-agricultural activities. Archaeologists are alerted to this process by the distribution of more standardised implements, weapons and styles of pottery. These things also help in the identification of the favoured areas – most notably, and at different times, that great trail across the north from the Indus to the Gangetic basin, plus Gujarat, Malwa and the Orissan littoral in mid-India. In the south a similar diversification is inferred, although here the archaeological display-case remains somewhat empty. Save for a few Stone Age productions, south India’s history has to wait until jump-started by a remarkable literary outpouring at the very end of the first millennium BC.
As crafts and trades prospered, specialisation encouraged congregation, and congregation urbanisation. Within the same favoured enclaves, ideological conformity, social stratification and political formation followed. The models for each – for an effective religion, a harmonious society and a legitimate state – married local elements and imperatives with a set of norms derived from the propagandised traditions of an Indo-Aryan people who had emerged in north India by 1000 BC. These Indo-Aryans were probably outsiders and, as well as a strong sense of community centred on elaborate rites of sacrifice, they possessed in the Sanskrit language an exceptionally versatile and persuasive medium of communication. Had India been as open and uniform a land as geography suggests, no doubt Sanskrit and its speakers would speedily have prevailed. They did do so over much of north India, but not speedily and not without compromise. Further afield, in west, east and central India and the Deccan, the process somewhat misleadingly known as ‘Aryanisation’ took even longer and involved so much compromise with local elements that hybridisation seems a fairer description. From it emerged most of the different languages and different social conformations which, heightened by different historical experiences, have given India its regional diversity, and which still distinguish the Bengali from the Gujarati or the Panjabi from the Maratha.
The pantheon of spirits and deities worshipped in each zone, or region, typified this process of hybridisation, with Indo-Aryan gods forsaking their original personae to accommodate a host of local cults. Thus did Lord Vishnu acquire his long list of avatars or ‘incarnations’. In parts of India this process of divine hybridisation is still continuing. Every year each village in the vicinity of Pudukottai in Tamil Nadu commissions from the local potter a large terracotta horse for the use of Lord Ayanar. Astride his splendid new mount, Ayanar will ride the village bounds at night, protecting the crops and warding off smallpox. But who is this Ayanar? None other than Lord Shiva, they tell you. The pan-Indian Shiva, himself an amalgam of various cults, looks to be only now in the process of usurping the Tamil Lord Ayanar. But it could be the other way round. To the people of Pudukottai it is Ayanar who is assuming the attributes of Shiva.
As with gods, so with the different languages spoken in India’s zonal regions. In its earliest form Marathi, the language now mainly spoken in Maharashtra, betrayed Dravidian as well as Sanskrit features. At some point a local form of early Dravidian, a language family now represented only in the south, is thought to have been overlain by the more prestigious and universal Sanskrit. But the precedence as between local indigenous elements and Sanskritic or Aryan influences is not clear. Did Sanskrit speakers domiciled in Maharashtra slowly absorb proto-Dravidian inflexions? Or was that too the other way round?
A more clear-cut example of Aryanisation/Sanskritisation is provided by the many attempts to replicate the topography featured in the Sanskrit epics. By word of mouth core elements of the Mahabharata and Ramayana had early penetrated to most of India.
