* * * * * INTRODUCTION Northwestern Louisiana was occupied by the Caddo Indians during the period of early Spanish, French, and American contacts. By combining history and archaeology, the Caddo story can be traced back for a thousand years—a unique opportunity made possible by a long tradition of distinctive traits, especially in pottery forms and decorations. Our story of the Caddo Indians in Louisiana, therefore, begins around A.D. 800-900 and can be traced by archaeology well into the historic period. The center of Caddoan occupation during contact times and throughout their prehistoric development was along Red River and its tributaries, with extensions to other river valleys in the four-state area of northern Louisiana, southwestern Arkansas, eastern Texas, and eastern Oklahoma. The successful agriculture of these farming peoples was best adapted to the fertile valleys of major streams like the Red, Sabine, Angelina, Ouachita and—in Oklahoma—the Canadian and Arkansas rivers. In spite of their linguistic (language) connections with Plains tribes like the Wichita, Pawnee, and Arikara, the Caddos in Louisiana had customs much like those of other Southeastern tribes. They maintained trade and cultural contacts with the lower Mississippi Valley tribes of eastern and southern Louisiana for many centuries. PRE-CADDOAN DEVELOPMENTS Northwestern Louisiana was occupied for thousands of years before the beginnings of Caddo culture. In the upland areas, along small streams and bordering the river valleys, projectile points and tools of Early and Late Paleo-Indian peoples have been found (Webb 1948b; Gagliano and Gregory 1965). In the western plains, the makers of the fluted Clovis and Folsom points hunted now extinct types of big game (mammoth, mastodon, sloth) between 10,000 and 8000 B.C. The later Plainview, Angostura, and Scottsbluff points have been found with the extinct large bison. Since all of these distinctive projectile point types have been found in the Louisiana uplands and mastodon bones, teeth, and tusks have been found in Red River Valley, big game hunting was possible in the state. However, no camp or kill sites of Paleo-Indian people have been found thus far.
