Reader's Guide
The Midwest's significance stems from its role as a transportation crossroads for river boats, railroads, autos, trucks, and airplanes, facilitated by its central location. Politically, the region includes multiple swing states, making it heavily contested and often decisive in elections. The region's pre-Columbian history includes Mississippian culture, which built mound structures and supported large populations through maize, beans, and squash agriculture.
