With upwards of 30,000 inhabitants at its peak in about 1100 AD, Cahokia, Illinois remained North America's first and biggest real city until the Northeast's population exploded in the late 18th century. This urban center of the Mississippi culture had organized leadership, commerce and a penchant for mound-building. Monk's Mound, the largest at 100 feet tall, dominates the site and was probably a mighty foundation for the home of the resident spiritual leader.
