Indus Valley Civilization. It was a Bronze Age civilization that flourished in the northwestern regions of South Asia, primarily in what is now modern-day Pakistan and northwestern India. This sophisticated urban culture, contemporaneous with ancient Egypt and Mesopotamia, is renowned for its advanced city planning, standardized weights, and extensive trade networks. Its discovery in the 1920s dramatically altered the understanding of early subcontinental history.

History and discovery

Initial clues emerged in the mid-19th century with reports of mysterious bricks near the village of Harappa, used in constructing the Lahore-Multan railway. Systematic excavation began in the 1920s under the direction of John Marshall of the Archaeological Survey of India, who first identified the distinct culture. Further major work was conducted by Mortimer Wheeler at sites like Mohenjo-daro and Harappa, establishing the civilization's urban character. Later, discoveries by scholars like George F. Dales and teams from institutions like the University of California, Berkeley expanded its known range. The identification of the site of Lothal in Gujarat revealed its maritime connections.

Geography and chronology

The civilization's core was in the basins of the Indus River and the now-seasonal Ghaggar-Hakra River, with settlements stretching from the foothills of the Himalayas to the coast of the Arabian Sea near modern Karachi. Its mature phase, known as the Harappan period, is dated from approximately 2600 to 1900 BCE, following earlier regional cultures like that of Mehrgarh. Important sites extended as far east as the Ganges-Yamuna Doab at Alamgirpur and as far south as Daimabad in Maharashtra. The climate during its peak is believed to have been wetter, supporting the extensive agriculture that underpinned its cities.

Society and culture

Evidence suggests a society with low wealth disparity, lacking obvious palaces or temples dedicated to singular rulers or deities. Artistic expression is found in finely crafted seals depicting animals like the unicorn, zebu, and elephant, as well as in figurines, such as the famous Dancing Girl from Mohenjo-daro. Personal adornment included elaborate jewelry made from materials like carnelian, lapis lazuli, and gold. Ritual practices remain enigmatic, though structures like the Great Bath and fire altars at Kalibangan suggest ceremonial or religious functions.

Cities and architecture

Urban centers were masterpieces of planning, built on a grid system with standardized baked bricks. Major cities like Mohenjo-daro and Dholavira featured sophisticated water management, including wells, drainage systems, and reservoirs. Harappa and Mohenjo-daro were dominated by a raised citadel area, while Dholavira had a unique middle town and lower town configuration. Residential architecture varied, with some larger houses featuring courtyards and private wells. Notable structures include the aforementioned Great Bath and the massive granaries found at Harappa and Mohenjo-daro.

Economy and technology

The economy was based on intensive agriculture, cultivating wheat, barley, and cotton, and domesticating animals like the water buffalo. It was supported by a vast internal and external trade network, evidenced by standardized weights and measures. Trade goods reached Mesopotamia, as recorded in Akkadian texts mentioning Meluhha, and the Persian Gulf, with outposts like Shortugai in Afghanistan sourcing lapis lazuli. Technological achievements included advanced metallurgy with copper and bronze, the use of the potter's wheel, and the world's first known instance of cotton spinning and weaving.

Script and language

The civilization used a still-undeciphered Indus script, found primarily on stamp seals, tablets, and pottery. The script, consisting of over 400 distinct signs, shows no clear connection to later Brahmi or Kharosthi scripts. The underlying language remains unknown, with proposed links to the hypothetical Proto-Dravidian or other language families. The absence of lengthy bilingual inscriptions, unlike the Rosetta Stone for Egyptian hieroglyphs, has hindered decipherment efforts by scholars from the University of Helsinki to the Tamil Nadu archaeological department.

Decline and legacy

Around 1900 BCE, a period of de-urbanization began, marked by the abandonment of major cities. Proposed causes include climatic shifts, such as the drying of the Ghaggar-Hakra River, changes in the course of the Indus River, and possible invasions or migrations. The subsequent Cemetery H culture and Ochre Coloured Pottery culture show some continuities in regions like the Punjab. Elements of its culture, including ritual practices and artistic motifs, may have persisted and been absorbed into the later Vedic period and the rise of early historic states, forming a foundational layer of South Asian civilization.
