Long ago, many people lived together. 
These people grew lots of corn. This helped them have more food. Because they had food, they could live in big towns. One big town was called Cahokia. 
They also made beautiful things. They made pots using shells. They even made art from copper. They traded these items with far away lands.
Later, the weather changed. It became very cold and dry. This made it hard to grow corn. Many people had to move to new places.
Some groups stayed and kept their ways. They were very special. It is amazing how they lived.
The Mississippian culture was a group of Native American societies. They lived in the Midwest and Southeast. This was from about 800 to 1600 CE. 
These people were great builders. They made large mounds out of earth. These mounds were often shaped like pyramids. People built homes and temples on top of them. 
They grew a lot of maize, which is corn. This food helped them build big towns. One very large city was Cahokia. It was in what is now Illinois. 
They were also skilled at making things. They used shells to help make clay pots. They also hammered copper to make art. They traded these goods over long distances. 
Later, the weather changed. It became cold and dry. This made it hard to grow corn. Many people moved away from the big cities. Some groups, like the Natchez, kept their ways for a long time.
The Mississippian culture was a group of Native American societies. They lived in the Midwest and Southeast. These groups flourished from about 800 to 1600 CE. 

Life in these societies changed as they grew. Most people began to farm maize, which is corn. This large-scale farming helped them feed many people. It also allowed some people to focus on crafts. They made pottery using crushed river shells to strengthen the clay. They also worked with copper. They hammered the metal to make beautiful plates and decorations. 
The history of these people has three main parts. The Early Mississippian period began around 1200 CE. During this time, groups moved into larger towns. The Middle Mississippian period was the peak of their culture. This happened around 1400 CE. This was when their largest cities grew very big. The Late Mississippian period began before 1540 CE. During this time, many people began to move away. Some groups faced hard times due to changes in the world. 
Cahokia was the largest and most important city. It was located in present-day southern Illinois. It was a major religious center for many people. 
Many things changed for the Mississippians over time. Around 1200 to 1800 CE, the climate changed. This period is called the Little Ice Age. It became much colder and drier. This made it very hard to grow enough corn. Many people left the big cities to find better land. 
The Mississippian culture was a collection of Native American societies. These groups flourished across the Midwestern, Eastern, and Southeastern United States. They lived from approximately 800 to 1600 CE. 

One of the most famous traits was the construction of platform mounds. These were large, truncated earthen pyramids. They were usually square or rectangular in shape. Sometimes they were even circular. People built structures on top of these mounds. These buildings served as domestic houses, temples, or burial sites. 
Mississippian societies were organized through complex chiefdoms. This is a type of social organization where power is centralized. A few people or even one leader held both political and religious power. This led to institutionalized social inequality. This means some people had more status and resources than others. This social structure often followed a settlement hierarchy. In this system, one major center controlled many smaller communities. These smaller villages might have had fewer mounds than the main center.
Religion was a central part of their lives. They practiced a belief system called the Southeastern Ceremonial Complex (SECC). This is also known as the Southern Cult. SECC items are found in many places. They range from Wisconsin to the Gulf Coast. They also extend from Florida to Oklahoma. These religious ideas were often tied to ritual games. One such game was called chunkey. They also worked with copper for ritual objects. They used a process called annealing to shape the metal. This involved heating and cooling the copper to make it easier to work. They made beautiful copper plates and other decorations. 
Historians divide the Mississippian period into three main stages. The Early Mississippian period began around 1200 CE. During this time, groups moved away from tribal lifeways. They embraced sedentism, which means living in one place. They also moved toward more centralized government. The Middle Mississippian period was the apex of the culture. This was the peak of their power and size. This era saw the expansion of major metropolises like Cahokia. 
Cahokia was the most important site in the entire culture. It was located in present-day southern Illinois. It was the largest Pre-Columbian settlement north of Mexico. Cahokia was a major religious and ceremonial center. Archaeologists have found many amazing things there. They found evidence of astronomy at Cahokia Woodhenge. They also found ritual retainer burials in Mound 72. 
Many factors caused the Mississippian culture to change. Around 1200 to 1800 CE, the world experienced the Little Ice Age. This was a period of global climate change. It brought colder conditions and less moisture. This lack of water made it hard to grow maize. Scholars believe this drought, along with overhunting, forced people to leave large sites.
