The End of the Civilisation
The decline of the Harappan civilisation began around 1900 BCE, evidenced by the abandonment of significant sites such as Cholistan. By 1800 BCE, most Mature Harappan settlements underwent a major transformation, shifting towards new settlements in Gujarat, Haryana, and western Uttar Pradesh. This transition marked the beginning of the Late Harappan period characterized by a reduction in the production and use of distinctive artefacts. Notably, crafting traditions such as the making of seals, beads, and weights, alongside long-distance trade, dwindled.
Several hypotheses concerning the reasons for the decline have been proposed, including climatic changes, deforestation, floods, the shifting of river systems, and overexploitation of resources. While some explanations are applicable to specific settlements, they do not collectively account for the overarching collapse of the entire civilisation.
Key indicators of this decline include the loss of a unified governance system, loss of writing, and a shift to localized weights away from standardized systems. Settlements that remained occupied showcased material culture indicative of a more rural way of life prevalent in successor cultures. Ultimately, the subcontinent saw a lapse of over a millennium before new urban centres arose in different regions, signifying a dramatic cultural and social transition.
