Migration has been a central factor in African history. It is likely that the human species started spreading on the planet within and outside of Africa between 2 and 2.5 million years ago. Although the earliest stages of human migrations are the subject of intense debate, most hypotheses concentrate on movements that occurred in the African continent. In historical times, African migrations can be divided into two broad sub-fields looking at, respectively: people moving because they were forced to and people choosing to move on their own free will. Africa has been the source of the largest forced migrations in history. The trans-Atlantic slave trade was the largest long-distance forced migration of people, even though it happened over a shorter period than the trans-Saharan and Indian Ocean slave trades. Within Africa, trade across complementary ecological zones and the seasonality of production propelled free migrations of traders and workers involved in long distance trade. Following the abolition of slavery and the slave trade, free labor migrations rose in importance. European colonialism introduced the need for cash that was often only accessible in cities and areas of cash crop production. It was also responsible for the introduction of new forms of forced labor required for the building and maintenance of colonial infrastructure. The rise of development as a rationale for the government of African societies influenced migrations in multiple ways through national and international policies aimed at channeling people’s mobility. In the last two centuries, African migrants have been unfolding projects of self-development by traveling to places where they hoped to find better opportunities. Yet contemporary trafficking and displacements caused by wars, intolerance, and natural catastrophes attest to the continuing relevance of violence as a key aspect of the experience of African migrants.
