The rains in the foothills seem to have been enough to hold the rural Harapans over for the next millennium, but even those would eventually dry up, likely contributing to their ultimate demise. The big surprise of the research, Giosan notes, is how far-flung the roots of that climate change may have been. That in turn pushed storms down into the Mediterranean, leading to an upswing in winter monsoons over the Indus valley.
This is just the beginning—sea level rise due to climate change can lead to huge migrations from low lying regions like Bangladesh, or from hurricane-prone regions in the southern U. Political and social convulsions can then follow.

The Indus civilization was the largest—but least known—of the first great urban cultures that also included Egypt and Mesopotamia.
Named for one of their largest cities, the Harappans relied on river floods to fuel their agricultural surpluses. Today, numerous remains of the Harappan settlements are located in a vast desert region far from any flowing river.
Syvitski, University of Colorado. Weakened monsoons and reduced run-off from the mountains tamed the wild Indus and its Himalayan tributaries enough to enable agriculture along their valleys. During the early and mature phases of the Harappan civilization, settlements bloomed along the Indus from the coast to the hills fronting the Himalayas and along the most likely course of the mythical River Sarasvati, in what is now a waterless region, part of the Thar Desert.
With continued aridification, the population moved eastward toward the Ganges basin, where summer monsoon rains remained reliable, and winter monsoon rains increased marking a shift toward small farming communities and the decline of cities during late Harappan times. He uses techniques that span isotope geochemistry, next generation DNA sequencing, and satellite tagging to study the ecology of a wide variety of ocean species.
He recently discovered that blue sharks use warm water ocean tunnels, or eddies, to dive to the ocean twilight zone, where they forage in nutrient-rich waters hundreds of meters down. Born in New Zealand, Simon received his B. Other aspects of the civilisation are even more perplexing. The chief cities show no clear signs of being fortified. No armour and no indisputably military weapon — as opposed to knives, spears and arrows designed for hunting animals — has been found.
Nor is there evidence of the horse, an animal well suited to raiding parties, which later became common in the region. In nearly a century of excavations, archaeologists have uncovered just one depiction of humans fighting, and it is a partly mythical scene showing a female deity with the horns of a goat and the body of a tiger. There is a total absence of conspicuous royal palaces and grand temples, no monumental depiction of kings and other rulers, not much difference between the homes of rich and poor, no sign of differing diets in the bones of buried skeletons and no evidence of slavery.
All this stands in stark contrast with the ziggurats of Mesopotamia and pharaohs of ancient Egypt. There are some who find a complete absence of war and conflict not credible. He argues that knives, spears and the like could have been used on humans as well as animals, and points out that the ancient Maya were once thought to be exceptionally peace-loving — until their hieroglyphs were deciphered, revealing stories of exceptionally bloody battles, sacrifice and torture.
Who knows what the Indus script might reveal if it is deciphered? Most large societies lean on centralised governments to enforce the rule of law.
Yet the only Indus sculpture that might conceivably depict a ruler is a small meditative bust of a bearded and cloaked man with partly closed eyes. Nonetheless, big engineering projects in the Indus valley would suggest some guiding authority existed to mobilise, direct and provision the workforce. Take the vast stone platforms that underlie various cities.
They were built to raise buildings and streets above the level of the annual floods of the Indus river. Additional platforms were sometimes built on top, to further raise individual structures. At Mohenjo-daro, the foundational platform is metres wide, metres long and 5 metres tall.
Indus excavator and scholar Gregory Possehl of the University of Pennsylvania calculated that it would have taken 10, men just over a year to build. This would have required some kind of central authority to mobilise and direct labourers. Of course, More made allowances for slavery in his Utopia, so perhaps this is just one more parallel between the fictional and real worlds. Commercial networks spread over a vast area are another indication of a centralised authority.
Lapis lazuli mined close to the trading post of Shortugai in what is now Afghanistan is found as far afield as Egypt. Goods were undoubtedly shipped via the Indus river and its tributaries, but many must have travelled overland. And then there are the stone weights. They were standardised for commerce throughout the Indus valley and clearly worked well: the system survived long after the civilisation disappeared. Between and distinct Indus symbols that indicate a language have been found on ceramics, seals, and tablets, though the language remains entirely unknown to this day.
Pashupati : Discovered at Mohenjo-daro, this seal depicts a seated, horned figure surrounded by animals, who is commonly interpreted to be Pashupati, the Lord of Cattle. Socially, the Indus Civilization appears to have been relatively egalitarian in nature. All homes within its various cities had access to water and drainage facilities and were generally equal in size.
The evidence for planned settlements and the uniformity of Harappan artifacts suggests a strong organizational or governing force in the Indus Valley Civilization, though archaeological records provide no immediate answers. By BCE, many of the cities had been abandoned. The reason for the decline of the civilization is unknown, but it is theorized to be due to enemy invasion throughout the area, a change in climate to significantly cooler and drier conditions, or the disappearance of the Ghaggar-Hakra River.
After the collapse, regional cultures emerged that continued to show the influence of the Indus Valley Civilization to varying degrees. The Vedic period in India c. The Vedic period or Vedic age in India was a period in history during which the Vedas, the oldest scriptures of Hinduism, were composed.
The time span of the period is uncertain, though it is thought to span from BCE to about BCE, with BCE suggested as a terminus ante quem the latest possible time for all Vedic Sanskrit literature. The transmission of stories in the Vedic period was by oral tradition alone, and a literary tradition began only in post-Vedic times. The associated culture, sometimes referred to as the Vedic civilization, was probably centered in the northern and northwestern parts of the Indian subcontinent, but it has now spread and constitutes the basis of contemporary Indian culture.
In the 11th century BCE, the Vedic society transitioned from semi-nomadic life to settled agriculture. This transition led to an increase in trade and increased competition and conflicts over resources, such as land and water. However, after BCE, the use of iron axes and ploughs enabled the clearing of jungles, and the Vedic kingdoms were able to expand along the Gangetic plains, ushering in the later Vedic age.

Here, the river Indus is shown by its Sanskrit name Sindhu. The location of Vedic shakhas is labelled in green, and the Thar desert is in orange. By the 6th century BCE, various political units consolidated into large kingdoms called Mahajanapadas. The process of urbanization began in these kingdoms, and commerce and travel—even over regions separated by large distances—became easy.
The end of Vedic India is marked by linguistic, cultural, and political changes. The invasion of Darius I of the Indus valley in the early 6th century BCE marks the beginning of outside influence that continued in the kingdoms of the Indo—Greeks.
After the end of the Vedic period, the Mahajanapadas period in turn gave way to the Maurya Empire from c. Crafts within Vedic culture include that of chariot-making, cart-making, carpentry, metal-working creating instruments such as razors, bangles, and axes , tanning, bow-making, sewing, weaving, and making mats from grass and reeds.
Many of these might have required full-time specialists. The use of iron implements krishna-ayas or shyama-ayas, literally meaning black metal or dark metal increased in the later Vedic age, as did new crafts and occupations such as leather work, pottery, astrology, jewelry, dying, and vintnery. Apart from copper, bronze , and gold, later Vedic texts also mention tin, lead, and silver. The Vedas are a large body of texts that originated in the Vedic period.
Composed in Vedic Sanskrit, the texts constitute the oldest layer of Sanskrit literature and the oldest scriptures of Hinduism. The reconstruction of the history of Vedic India is based on text-internal details. Linguistically, the Vedic texts could be classified in five chronological strata:.
The Upanishads are a collection of philosophical texts that form the theoretical basis for the Hindu religion. The Sanskrit term upanishad means sitting down near, implying sitting near a teacher to receive instruction.
Also known as Vedanta, they are considered by orthodox Hindus to contain the revealed truths Sruti concerning the nature of ultimate reality brahman , and describe the character and form of human salvation moksha.
