The Indus Valley Cities

c. 2600 BCE — South Asia, Indus Valley Civilization

Today: Pakistan and northwest India (Mohenjo-daro and Harappa)

Across a territory larger than ancient Egypt and Mesopotamia combined, the Indus Valley Civilization built hundreds of cities of astonishing order — grid-planned streets, standardized fired bricks, covered sewers, and public baths. Yet archaeologists have found no palaces, no royal tombs, no grand temples, and no sign of an army: a sophisticated urban order seemingly without kings or war, its writing still undeciphered. It stands as proof that complex civilization did not have to be built the Mesopotamian way — around a strongman and a shrine.

Worth knowing: Indus weights were so precisely standardized that a stone weight from one city matches one from 500 miles away to within a fraction of a gram — a shared system enforced across an area larger than Western Europe, with no visible enforcer.

Pattern: State formation & institutional founding — A durable new order — a state, an institution, a system of rule — is deliberately built and consolidated, outlasting the people who founded it.
