World Wars I and II were very probably the most destructive conflicts in African history. In terms of the human costs—the numbers of people mobilized, the scale of violence and destruction experienced--as well as their enduring political and social impact, no other previous conflicts are comparable, particularly over such short periods as four and ten years, respectively. All told, about 4,500,000 African soldiers and military laborers were mobilized during these wars and about 2,000,000 likely died.
Mobilization on this scale among African peasant societies was only sustainable because they were linked to the industrial economies of a handful of West Central European nation states at the core of the global commercial infrastructure, which invariably subordinated African interests to European imperial imperatives. Militarily, these were expressed in two ways: by the use of African soldiers and supporting military laborers to conquer or defend colonies on the continent, or by the export of African combat troops and laborers overseas—in numbers far exceeding comparable decades during the 18th-century peak of the transatlantic slave trade—to Europe and Asia to augment Allied armies there.
The destructive consequences of these wars were distributed unevenly across the continent. In some areas of Africa, human losses and physical devastation frequently approximated or surpassed the worst suffering experienced in Europe itself; yet, in other areas of the continent, Africans remained virtually untouched by these wars.
These conflicts contributed to an ever-growing assertiveness of African human rights in the face of European claims to racial supremacy that led after 1945 to the restoration of African sovereignty throughout most of the continent. On a personal level, however, most Africans received very little for their wartime sacrifices. Far more often, surviving veterans returned to their homes with an enhanced knowledge of the wider world, perhaps a modicum of newly acquired personal prestige within their respective societies, but little else.

From at least 3.4 million years ago to historic periods, humans and their ancestors used stone as the raw material for tool production. Archeologists find stone tools on all the planet’s habitable landmasses, even in its cold and ecologically sparse Arctic regions. Their ubiquity and durability inform archeologists about important dimensions of human behavioral variability. Stone tools’ durability also gives them the ability to contribute to the study of long-term historical processes and the deeper regularities and continuities underlying processes of change. Over the last two millennia as ceramics, livestock, European goods, and eventually Europeans themselves arrived in southern Africa, stone tools remained. As social, environmental, economic, and organizational upheavals buffeted African hunter-gatherers, they used stone tools to persist in often marginal landscapes. Indigenous Africans’ persistence in the environment of their evolutionary origins is due in large part to these “small things forgotten.” Stone tools and their broader contexts of use provide one important piece of information to address some of archaeology and history’s “big issues,” such as resilience in small-scale societies, questions of human mobility and migrations, and the interactions of humans with their environments. Yet, stone tools differ in important ways from the technologies historians are likely to be familiar with, such as ceramics and metallurgy, in being reductive. While ceramics are made by adding and manipulating clay-like substances, stone tools are made by removing material through the actions of grinding, pecking, or fracture. Metals sit somewhere in between ceramics and stone: they can be made through the reduction of ores, but they can also be made through additive processes when one includes recycling of old metals. Stone-tool technologies can also be more easily and independently reinvented than these other technologies. These distinctions, along with the details of stone tool production and use, hold significance for historians wishing to investigate the role of technology in social organization, economy, consumption, contact, and cultural change.
