Explanation:

The Mississippians were part of Native Indian communities. They originally lived in the Mississippi River Valley, known as farmers settled in river valleys who cultivated corn, beans and squash which came to be known as three sister crops. As the European began to arrive in the southeast, the Native caught European diseases and died. The desire for European goods caused Mississippians to relocate closer or distant from European settlements. The native chiefdom, and authority structure destroyed with the coming of European trade which led people to spread around the region.
