Okay, so Mississippian culture was a way of life for people who lived in what is now the southeastern United States from about AD 800 to 1600. They were called the Mississippian people because they lived near the Mississippi River.
These people were skilled farmers and grew crops like corn, beans, squash, and sunflowers. They also hunted and fished for food.
One thing that was very important to the Mississippian people was having leaders who could make decisions for the group. They built large cities with houses made of mud and straw that could hold lots of people.
One of the most famous sites of the Mississippian culture is called Cahokia, which was a city located in what is now Illinois. It had a huge pyramid-shaped mound that was used for religious ceremonies and was bigger than any other structure in North America until European settlers came.
The Mississippian people also made beautiful pottery and jewelry, and they liked to decorate their bodies with tattoos and piercings.
When European settlers arrived in the area, the Mississippian culture began to decline and eventually disappeared. But we can still learn about their amazing way of life by studying their artifacts and the sites they left behind.
