This was accompanied by a homogenization of material culture (e.g. pottery and architectural styles) that divided the smaller settlements beforehand. Mound construction increased across the region in the 11th century in the floodplain and, for the first time, in the uplands to the east. Some mounds were built on earlier settlement locations—arguably by descendants emphasizing their particular ancestral positions in the new social order. All villages experienced either renewal and construction efforts turning them into mound centers, or were depopulated to become just a few households or a single farmstead.<ref name=":6" /> New settlement types including nucleated settlements, mound centers, small dispersed clusters of houses, and single-family farmsteads appeared throughout the region. The city's complex construction of earthen mounds required digging, excavation and transportation by hand using woven baskets. Construction made use of {{convert|55|e6ft3|e6m3|abbr=off|sp=us}} of earth, and much of the work was accomplished over decades.

The city has been traditionally thought to have been a maize-centric civilization, the crop having been introduced to the region around AD 900.<ref>{{Cite journal |last=Emerson |first=Thomas E. |date=2002 |title=An Introduction to Cahokia 2002: Diversity, Complexity, and History |url=https://www.jstor.org/stable/20708175 |journal=Midcontinental Journal of Archaeology |volume=27 |issue=2 |pages=127–148 |issn=0146-1109}}</ref> While maize is often credited with enabling Cahokia's early population growth, more recent research has suggested that Cahokian diets were quite varied, especially in the city's early period of existence. A diversity of crops, such as [[Chenopodium|goosefoot]] and [[Iva annua|sumpweed]] from the [[Eastern Agricultural Complex]], were grown and eaten at Cahokia.<ref name=":8" /> Thomas Emerson and Kristin Hedman attribute the discovery of Cahokian individuals with low-maize diets to the existence of hunter-gatherer immigrant communities who had not yet adopted maize as a staple food source.<ref name=":2" /> Residents of outlying areas relied heavily on maize for subsistence, while residents of Cahokia's city center enjoyed more diverse diets. One interpretation is that higher levels of maize consumption may be correlated with a lower social status among Cahokian residents.<ref name=":4" /> The impact that Cahokian agriculture had on the environment, and its relationship to the city's ultimate collapse, is hotly debated. The depletion of farming soil surrounding Cahokia may have led to a decline in food resources that doomed the city. Jane Mt. Pleasant, however, argues that these models of Cahokia's soil longevity are flawed, because it is based on modern understandings of crop yields that assume the use of plows. Cahokians' exclusive use of hand tools was less damaging to the soil and thus may have maintained soil quality far longer than is typical today, making a rapid collapse of agricultural productivity in Cahokia less likely.<ref>{{Cite journal |last=Mt.

Richter|Daniel Richter]] notes that the apex of the city occurred during the [[Medieval Warming Period]]. This period appears to have fostered an agricultural revolution in upper North America, as the [[Three Sisters (agriculture)|three-fold crops]] of [[maize]], beans ([[legumes]]), and gourds ([[Cucurbita|squash]]) were developed and adapted or bred to the temperate climates of the north from their origins in [[Mesoamerica]]. Richter also notes that Cahokia's advanced development coincided with the development in the Southwest of the [[Chaco Canyon]] society, which also produced large-scale works in an apparent socially stratified society. The decline of the city coincides with the [[Little Ice Age]], although by then, the three-fold agriculture remained well-established throughout temperate North America.<ref>{{cite book |author=Richter, Daniel K. |title=Before the Revolution: America's Ancient Pasts |publisher=Belknap - Harvard University Press |year=2011 |isbn=9780674055803 |location=Cambridge, MA |pages=20–21}}</ref> ==Notable features== The original site contained 120 earthen mounds over an area of {{convert|6|sqmi|km2|0}}, of which 80 remain today.

Most of these mounds were leveled during the development of St. Louis, and much of their material was reused in construction projects. One survivor of these mounds is [[Sugarloaf Mound]].

It is {{convert|140|mi|km|abbr=on}} southeast of Cahokia, located in the floodplain of the [[Ohio River]]. With a total of 19 mounds at the complex, it is considered the fifth-largest Mississippian site in terms of the number of monuments.
