The Indus Valley Civilization existed through its early years of 3300-1300 BCE, and its mature period of 2600-1900 BCE. The area of this civilization extended along the Indus River from what today is northeast Afghanistan, into Pakistan and northwest India. The Indus Civilization was the most widespread of the three early civilizations of the ancient world, along with Ancient Egypt and Mesopotamia. Harappa and Mohenjo-daro were thought to be the two great cities of the Indus Valley Civilization, emerging around 2600 BCE along the Indus River Valley in the Sindh and Punjab provinces of Pakistan. Their discovery and excavation in the 19th and 20th centuries provided important archaeological data about ancient cultures.

Indus Valley Civilization

The Indus Valley Civilization was one of the three “Ancient East” societies that are considered to be the cradles of civilization of the old world of man, and are among the most widespread; the other two “Ancient East” societies are Mesopotamia and Pharonic Egypt. The lifespan of the Indus Valley Civilization is often separated into three phases: Early Harappan Phase (3300-2600 BCE), Mature Harappan Phase (2600-1900 BCE) and Late Harappan Phase (1900-1300 BCE).

At its peak, the Indus Valley Civilization may had a population of over five million people. It is considered a Bronze Age society, and inhabitants of the ancient Indus River Valley developed new techniques in metallurgy—the science of working with copper, bronze, lead, and tin. They also performed intricate handicraft, especially using products made of the semi-precious gemstone Carnelian, as well as seal carving— the cutting of patterns into the bottom face of a seal used for stamping. The Indus cities are noted for their urban planning, baked brick houses, elaborate drainage systems, water supply systems, and clusters of large, non-residential buildings.

The Indus Valley Civilization is also known as the Harappan Civilization, after Harappa, the first of its sites to be excavated in the 1920s, in what was then the Punjab province of British India and is now in Pakistan. The discoveries of Harappa, and the site of its fellow Indus city Mohenjo-daro, were the culmination of work beginning in 1861 with the founding of the Archaeological Survey of India in the British Raj, the common name for British imperial rule over the Indian subcontinent from 1858 through 1947.

Harappa and Mohenjo-daro

Harappa was a fortified city in modern-day Pakistan that is believed to have been home to as many as 23,500 residents living in sculpted houses with flat roofs made of red sand and clay. The city spread over 150 hectares (370 acres) and had fortified administrative and religious centers of the same type used in Mohenjo-daro. The modern village of Harappa, used as a railway station during the Raj, is six kilometers (3.7 miles) from the ancient city site, which suffered heavy damage during the British period of rule.

Mohenjo-daro is thought to have been built in the 26th century BCE and became not only the largest city of the Indus Valley Civilization but one of the world’s earliest, major urban centers. Located west of the Indus River in the Larkana District, Mohenjo-daro was one of the most sophisticated cities of the period, with sophisticated engineering and urban planning. Cock-fighting was thought to have religious and ritual significance, with domesticated chickens bred for religion rather than food (although the city may have been a point of origin for the worldwide domestication of chickens). Mohenjo-daro was abandoned around 1900 BCE when the Indus Civilization went into sudden decline.

The ruins of Harappa were first described in 1842 by Charles Masson in his book, Narrative of Various Journeys in Balochistan, Afghanistan, the Panjab, & Kalât. In 1856, British engineers John and William Brunton were laying the East Indian Railway Company line connecting the cities of Karachi and Lahore, when their crew discovered hard, well-burnt bricks in the area and used them for ballast for the railroad track, unwittingly dismantling the ruins of the ancient city of Brahminabad.

Excavations

In 1912, John Faithfull Fleet, an English civil servant working with the Indian Civil Services, discovered several Harappan seals. This prompted an excavation campaign from 1921-1922 by Sir John Hubert Marshall, Director-General of the Archaeological Survey of India, which resulted in the discovery of Harappa. By 1931, much of Mohenjo-Daro had been excavated, while the next director of the Archaeological Survey of India, Sir Mortimer Wheeler, led additional excavations.

The Partition of India, in 1947, divided the country to create the new nation of Pakistan. The bulk of the archaeological finds that followed were inherited by Pakistan. By 1999, over 1,056 cities and settlements had been found, of which 96 have been excavated.
