Wisconsin's Mississippian people built large platform mounds with surrounding villages. The site at Aztalan was even surrounded by a stockade. This may suggest that there were conflicts between the people living within the stockade and those living outside it.
Social structure also changed with the introduction of Mississippian ideas. People who lived during this time experienced social inequality as they lived under religious or political rulers. Elite individuals received special privileges and goods from far away places. They possibly lived on the platform mounds and received exotic goods.
