Map of Missouri

History

Archaeological excavations along river valleys have shown continuous habitation since about 9000 BCE. Beginning before 1000 CE, the people of the Mississippian culture created regional political centers at present-day St. Louis and across the Mississippi River at Cahokia, near present-day Collinsville, Illinois. Their large cities included thousands of individual residences. Still, they are known for their surviving massive earthwork mounds, built for religious, political and social reasons, in platform, ridgetop and conical shapes. Cahokia was the center of a regional trading network that reached from the Great Lakes to the Gulf of Mexico. The civilization declined by 1400 CE, and most descendants left the area long before the arrival of Europeans.

Geography

Missouri borders eight different states, a figure equaled only by its neighbor, Tennessee. Missouri is bounded by Iowa on the north; by Illinois, Kentucky, and Tennessee across the Mississippi River on the east; on the south by Arkansas; and by Oklahoma, Kansas, and Nebraska (the last across the Missouri River) on the west. Whereas the northern and southern boundaries are straight lines, the Missouri Bootheel extends south between the St. Francis and the Mississippi rivers. The two largest rivers are the Mississippi (which defines the eastern boundary of the state) and the Missouri River (which flows from west to east through the state), essentially connecting the two largest metros of Kansas City and St. Louis.
