Cahokia

c. 1050 CE — Americas, Mississippian culture

Today: Near modern St. Louis, Missouri, USA

Across the river from where St. Louis stands today, the Mississippian people built Cahokia, the largest city in North America north of Mexico — a metropolis of perhaps 20,000 centered on enormous flat-topped earthen pyramids and a plaza aligned to the heavens. For a time it was larger than London. Then, over the 1300s, it was abandoned, likely amid climate stress and political strain — proof that the Americas held cities and states long before any European arrived to 'discover' them.

Worth knowing: Cahokia's largest earthen mound is broader at its base than the Great Pyramid of Giza — yet most Americans have never heard of the city, which once thrived where East St. Louis sits today.

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.
