Cahokia (AD 600-1400), one of the largest cities built by the ancient Cahokian civilization, was located just five miles east of what is now St. Louis. Like other mound builders, Cahokians planted family farms within the city to supply its urban dwellers with corn, squash, and sunflowers, among other foods and medicines. Cahokia’s neighborhoods included houses, large plazas, public buildings, and more than 100 monumental earthen mounds. Suburban towns radiated outward 50 miles in every direction from the city (Pauketat, 2009).
