The ancient city of Cahokia, located in present-day Illinois, did not have kings in the traditional sense. Instead, it was ruled by a council of elders and a powerful chief or "Great Sun" who was chosen from among the council members.

The Great Sun was a political and religious leader who oversaw the city's affairs and was responsible for maintaining order and justice. They were often adorned with special clothing and symbols of their power, such as eagle feathers, shell necklaces, and headdresses made of animal fur and feathers.

The Great Sun was also responsible for organizing religious ceremonies and rituals, which were an important part of Cahokian life. They often wore elaborate costumes and masks during these ceremonies, which were intended to appease the gods and ensure a successful harvest or hunting season.

Overall, the role of the Great Sun in Cahokian society was to maintain stability and balance between the various factions and clans that made up the city's population, as well as to serve as a spiritual leader and intermediary between the people and the gods.
