In this paper I discuss known and probable migrations and areas of settlement of proto-Mande and Mande-speaking groups during eight climate periods spanning the past eight millennia. Recent scholarship concerning west African climate patterns in past times has made feasible provisional periodizations of west African history that are independent of European-derived chronologies. Concomitantly, these historical periodizations offer provocative insights regarding such long-term processes as human migrations and settlement patterns; the diffusion of cultigens and domestic animals; the development of long- distance trade routes; and the use of horse cavalry in warfare. The provisional historical schema comprising eight climate periods and Map 1 depicting ecological zones are principally derived from the pioneering studies of Sharon E. Nicholson and of Susan and Roderick McIntosh, and from the analyses I have presented elsewhere: (1) The Atlantic Wet Phase which extended from ca. 5500 to ca. 2500 B.C., was succeeded by (2) a two-and-a-half millennia-long period of desiccation. (3) There was a six centuries-long transiton period between ca. 300 B.C. and ca. 300 A.D., during the latter part of which ecological conditions improved sufficiently to permit the development of intra- and trans- Saharan commerce. (4) Four centuries of moderate rainfall ca. 300-ca. 700, and (5) four centuries of abundant rainfall ca. 700-ca. 1100, were followed by (6) a four centuries long dry period extending from ca. 1100 to ca. 1500. (7) A brief wet period, ca. 1500-ca. 1630, preceded (8) a two centuries-long dry period lasting until ca. 1860
