TNPSC - INDUS VALLEY CIVILISATION - சிந்து சமவெளி நாகரிகம் | Indian History - Unit 1

The Indus Valley Civilization (IVC), also known as the Harappan Civilization, stands as one of the world's three earliest urban civilizations, alongside ancient Mesopotamia and Egypt. Flourishing in the Bronze Age (c. 3300–1300 BCE), its Mature Harappan Phase (c. 2600–1900 BCE) marked the peak of its urban development. Geographically, the IVC was the most extensive of the three, spreading across what is now modern-day Pakistan, northwest India, and parts of Afghanistan. It developed primarily in the alluvial plains of the Indus River and the now-drygar-Hakra river system, showcasing remarkable organization and a level of sophistication unmatched by many contemporary cultures. Chronology and Extent The history of the Indus Civilization is typically divided into several phases: Pre-Harappan (c. 7000–5500 BCE): The Neolithic period, exemplified by sites like Mehrgarh, shows the beginnings of settled agricultural life, animal domestication, and basic pottery. Early Harappan (c. 3300–2600 BCE): This transitional phase saw the emergence of rudimentary urban centers and cultural traits that would define the mature civilization. Trade networks began to establish themselves. Key sites include Kot Diji and Amri. Mature Harappan (c. 2600–1900 BCE): The high point of the civilization, characterized by widespread urbanization, advanced town planning, and standardized artifacts. The great cities of Harappa and Mohenjo-daro flourished during this time. Late Harappan (c. 1900–1300 BCE): A period of decline, marked by the abandonment of major cities and a shift in population towards the east and south. Urban features like uniform weights and writing began to disappear. At its height, the civilization covered over a million square kilometers. Major sites include Harappa (on the Ravi river) and Mohenjo-daro (on the Indus river) in Pakistan; and Lothal (with its famous dockyard), Dholavira, Kalibangan, and Rakhigarhi in India. Urban Planning and Architecture The most defining feature of the Indus Valley Civilization was its advanced urban planning. Unlike the organic growth of cities in Mesopotamia or Egypt, Harappan cities appear to have been purposefully conceived and constructed following a precise, standardized blueprint, suggesting a centralized, albeit mysterious, authority. Grid System and Standardization The major cities like Mohenjo-daro and Harappa were laid out on a precise grid pattern, with main streets running north-south and secondary streets running east-west, intersecting at right angles. This sophisticated geometric layout divided the city into rectangular blocks. Buildings were predominantly constructed using baked bricks of a remarkably uniform size (a standard ratio of 1:2:4, thickness:width:length), a technical feat that points to meticulous organization and control over labor and resources. City Division Most major cities were generally divided into two main parts: The Citadel: A smaller, raised platform on the west, possibly housing the ruling or administrative class, as well as significant public structures like the Granaries and the Great Bath at Mohenjo-daro. The Lower Town: A larger residential area on the east where the common people lived. Water Management and Sanitation The Harappans possessed the world's first known urban sanitation systems, which were far more advanced than those of contemporary civilizations. Drainage System: Every street and almost every house was connected to an elaborate. Decline of the Civilization Around 1900 BCE, the great cities began to enter the Late Harappan Phase and were gradually abandoned over the next few centuries. The collapse was not sudden or uniform but a slow process of de-urbanization, a decline in trade, and the disappearance of the standardized script and weights. The exact cause of the decline remains a subject of intense debate among scholars, but a combination of environmental factors is the most widely accepted theory: Climate Change and Aridity: A significant shift in monsoon patterns leading to increased aridity and severe droughts severely impacted the agricultural base. River System Changes: The Ghaggar-Hakra river system, which supported many eastern settlements, is believed to have dried up or changed its course due to tectonic disturbances, leading to water scarcity. Flooding: Evidence of excessive silt deposits in Mohenjo-daro suggests destructive, recurrent flooding. Loss of Trade: The decline of trade with Mesopotamia due to instability in the Middle East likely weakened the Harappan economy. The discredited Aryan Invasion Theory, which proposed that a violent incursion by Indo-Aryan people caused the sudden destruction, has been largely abandoned in favor of the gradual decline model due to ecological stress. Although the cities vanished, many cultural and technological traditions of the Indus Civilization persisted, influencing later cultures in South Asia.
