Why did people come to Cahokia?
We do not know why people chose to come to Cahokia, but it is located at an important confluence of the Mississippi River where the valley is wide and can hold a lot of people and farms. As Cahokia grew more powerful, more immigrants arrived, perhaps against their will as captives from war or by choice as families looking for work and a good life .
Why were the people next to Birdman buried?
Because the people next to the special grave goods and the young men and women a little farther away were buried at the same time as Birdman, many archaeologists think that they were human sacrifices who were killed to honor him or his family, show his power, or as an important religious act. The young men and women probably were forced to die and were chosen because they were not powerful people. However, the people next to Birdman may have chosen to die with him. A French colonist in 1725 witnessed the burial of a leader, named Tattooed Serpent, of the Natchez people in Mississippi. The Natchez had a similar way of life to people at Cahokia. At Tattooed Serpent’s funeral several commoners were killed, but some of his family and friends chose to join him in death. While we will never know for sure, it is possible that a similar event happened at Cahokia. Although Mound 72 tells a dramatic story, it is the only example of human sacrifice archaeologists have found at Cahokia and the practice was rare, possibly happening only once.
How did politics at Cahokia work?
There are two main ideas for how politics at Cahokia worked: a single, powerful leader, like a president or shared power between multiple leaders, like senators. Evidence for a single, strong leader includes one mound much bigger than the others, Monks Mound, that may have housed the most important family at Cahokia, and human sacrifice at Mound 72 (see ‘Religion, Power and Sacrifice’ section for more information). On the other hand, the fact that there are many large mounds at Cahokia, not just Monks Mound, suggests that power may have been shared. Most likely, there was one leader or group that was more important than others, but their power was not total.
Why are people buried at Mound 72?
People were buried in special ways because of their religious beliefs and some people were more powerful than others, having fancier grave goods and the power of life and death over commoners. Human sacrifice has happened throughout time all over the world. Cahokia shows us that human sacrifice is complicated – at Mound 72 some people were certainly forced to die, but others may have chosen to die along with someone they loved or found very important.
What did the Cahokians eat?
They also grew squash, sunflower and other domesticated crops and also ate a variety of wild plants. They fished in lakes and streams and hunted birds, deer, and occasionally animals like beavers and turtles. Isotopes in bone from burials (see ‘Religion, Power and Sacrifice’ section for more information) tells us that more powerful people at Cahokia ate more meat and probably had a healthier diet than commoners. Although many people were involved in getting or making food in some way, there still were many other jobs at Cahokia: you could be a potter, flintknapper, beadmaker, builder, healer, priest, leader, or some combination of all these. People had free time too, and for fun would play games like chunkey. To play chunkey, you roll a stone across a field and then try to throw a spear as close to the stone as possible before it stops rolling, sort of like a more exciting and dangerous game of bocce ball.
