<p>In the Zimbabwean past, farming societies utilized mineral resources for their own use and for exchange to local and regional populations, as well as to markets beyond African borders. Successful agriculture was constrained by environmental hazards, principally unpredictable and often inadequate rainfall. Farming communities managed this predicament in various ways. It is likely that some groups used mineral resources found in the vicinity of their settlements to produce materials or items to exchange. The social contexts that defined the nature of mineral production and exchange altered between the mid-first and mid-second millennium AD, as social ranks emerged and political and economic systems became increasingly complex. The thesis is a commentary on how the motivation of society to broaden its resource base, to improve the benefits to households and to society in general, contributed to the emergence of leaders and, ultimately, of an elite class. The focus of the research is on iron and copper production because the author has examined gold production thoroughly in a previous study. Four published papers outline the history of iron and copper production in Zimbabwe. The papers provide case studies of the scale and social context of iron and copper production and exchange.</p>
