Drawing on the latest archaeological fieldwork, Caddo Connections looks at the highly dynamic cultural landscape of the Caddo Area and its complex interconnections and exchanges with surrounding regions. The authors employ a multiscalar approach to examine cultural diversity through time and across space within the Caddo Area. They explore how and why this diversity developed, consider what allowed it to stabilize during the Mississippian period, and analyze changes following contact between historic Caddo peoples and Europeans. Looking beyond individual river valleys to the broader macroregion, they also address the linkages connecting the Caddo Area with the Southeast, southern Plains, and Southwest.
