Indus Valley / Harappan Civilization

A. Ghosh discovered Kalibangan during his Ghaggar valley exploration in 1953; it was later systematically excavated by B.B. Lal and B.K. Thapar.

Unlike the Egyptian Pharaohs, Harappans did not build massive monumental tombs or pyramid structures; they practiced simple pit/urn burials.

Harappan towns were laid out on a grid plan with straight streets intersecting at right angles.

In standard Harappan inhumation graves, the deceased were laid extended on their backs with the head towards the North.

Harappan baked and sun-dried bricks followed a remarkably uniform ratio across all settlements of 1:2:4 (e.g., 7 cm x 14 cm x 28 cm).

Harappan chert cubical weights followed a binary system (1, 2, 4, 8, 16, 32, 64... with 16 being the base unit) for smaller goods and decimal for larger.

Chanhudaro in Sindh is the only Indus Valley settlement that lacks a fortified upper citadel; it was primarily an industrial manufacturing town.

Rakhigarhi in the Hisar district of Haryana spans over 350 hectares, making it the largest known Harappan site.

To maintain privacy and reduce dust and noise, residential entrances opened into secondary side alleys rather than the main thoroughfares.

Terracotta replicas of ploughs have been excavated at Banawali (Haryana) and sites across the Cholistan desert.

Shortugai in Badakhshan, northern Afghanistan, was established by the Harappans primarily to control the trade of precious blue lapis lazuli.

Chanhudaro and Lothal had dedicated craft workshops for manufacturing carnelian, steatite, and agate beads, and shell artifacts.

Over 60% of animal seals from the Indus Valley feature the unicorn figure (one-horned animal in profile).

The Great Bath is located on the Citadel mound of Mohenjo-daro and was likely used for special ritual bathing.

Shortugai in northern Afghanistan has yielded clear archaeological evidence of Harappan irrigation canals.

Cylindrical rolling seals typical of Mesopotamia have been recovered in small numbers from Kalibangan and Mohenjo-daro.

Bath and kitchen water flowed through conduits in exterior walls into covered brick channels along the street fitted with inspection traps.

A thick layer of natural bitumen (tar/asphalt) was applied between the gypsum-mortared bricks to make the basin watertight.

In the Sindhi language, 'Mohenjo-daro' means 'Mound of the Dead'.

S.R. Rao conducted the extensive excavations at Lothal between 1955 and 1960 for the Archaeological Survey of India.

Chert (often sourced from the Rohri hills of Sindh) was precisely cut into cubical, non-marked balance weights.

Banawali is in Fatehabad district of Haryana, excavated by R.S. Bisht.

Gold was obtained from the riverbeds of the Himalayas and the southern mines in Kolar, Karnataka.

Dholavira contains a vast open stadium-like space between the Citadel and the Middle Town equipped with tiered seating for public gatherings.

Charles Masson visited Harappa in 1826 and was the first explorer to publish a description of the extensive brick ruins.

Nani Gopal Majumdar discovered Chanhudaro in 1931, which was later extensively excavated by Ernest Mackay.

Dilmun in Mesopotamian texts is widely identified with the island of Bahrain in the Persian Gulf.

According to standardized radiocarbon dating (D.P. Agrawal / NCERT), the Mature urban Harappan phase spans from 2600 BCE to 1900 BCE.

Mohenjo-daro yielded fine terracotta bulls with heavy dewlaps, prominent humps, and alert heads.

The Harappans were pioneers in cotton production; the Greek term 'Sindon' was derived from 'Sindhu' (Indus).

Faience was an artificial paste of crushed sand/quartz mixed with a binder and pigment, then baked to give a vitreous glassy sheen.

A series of rectangular and circular brick fire altars containing ash and charcoal were excavated at Kalibangan and Lothal.

Dholavira in the Rann of Kutch (Gujarat) had a unique tripartite division: Citadel, Middle Town, and Lower Town, with massive stone gateways.

Kalibangan translates to 'Black Bangles' (Kali = black, Bangan = bangles) due to the abundance of terracotta bangles found there.

Sutkagan Dor, located on the Makran coast near the Iran-Pakistan border on the Dasht River, is the westernmost known Harappan outpost.

Given the supreme focus on trade and commerce and the absence of temples or military palaces, an oligarchy of merchant councils is widely hypothesized.

Kot Diji is situated east of the Indus River across from Mohenjo-daro in the Khairpur district of Sindh, Pakistan.

Sotka Koh, located on the Shadi Kaur river near Pasni on the Makran coast, was a Harappan coastal trading post.

Gradual climate changes (weakened monsoons), river shifts (drying of Saraswati / avulsion of Indus), and ecological strain caused the de-urbanization; asteroid impacts are unproven.

Cemetery R-37 (Mature Harappan) and Cemetery H (Late Harappan) were excavated on the southern outskirts of Harappa.

Cramped spacing on the left edge confirms that Harappan script was written from right to left, and in alternating directions (boustrophedon) on long lines.

The drying up and river diversion of the Ghaggar-Hakra river system caused severe environmental degradation leading to the desertion of sites like Kalibangan and Banawali.

Dholavira features an advanced network of 16 interconnected rock-cut reservoirs that collected runoff water from seasonal streams.

Rangpur (Periods II B, II C, and III) and Rojdi represent the degenerate, non-urban Late Harappan culture (Lustrous Red Ware phase).

Cunningham published a report on a seal found at Harappa showing a bull without a hump, though he could not identify its Bronze Age origin.

Daimabad is located on the Pravara river in Ahmednagar district of Maharashtra, representing the southernmost Harappan horizon.

Most Harappan inscriptions are very brief, averaging about 5 symbols; the longest single text found on three seal faces contains 26 signs.
