Why the Indus Valley Civilization Is Called the Harappan Culture

The "Type Site" Convention in Archaeology

The Indus Valley Civilization (IVC) is named the Harappan Culture because Harappa (Punjab, Pakistan) was the first major site discovered and excavated in the 1920s.

How It Happened

1. 1826: British traveler Charles Masson notes ruins at Harappa.
2. 1850s: Railway contractors bricks from Harappa for ballast—destroying much of the site.
3. 1921–22: Daya Ram Sahni (ASI) conducts first systematic excavations at Harappa.
4. 1922: R.D. Banerji excavates Mohenjo-daro (Sindh), revealing the same culture.
5. 1924: Sir John Marshall announces the discovery of a "new civilization" in the Illustrated London News, naming it the Indus Valley Civilization after the river system, but the archaeological culture retains the name Harappan (or Mature Harappan) following the convention of naming a culture after its type site.

Why Not "Mohenjo-daro Culture"?

Harappa was excavated first. In archaeology, the type site (where the defining artifact assemblage is first recognized) gives its name to the culture—e.g., Clovis culture (Clovis, NM), La Tène culture (La Tène, Switzerland).

Other Names

• Indus-Sarasvati Civilization — preferred by some Indian scholars emphasizing the Ghaggar-Hakra (paleo-Sarasvati) river system.
• Harappan Phase — specifically the urban Mature period (2600–1900 BCE), distinct from Early Harappan and Late Harappan.
