People of African descent who migrated from their “homelands” constituted, and still constitute, important forces in many African cultures outside of their “homelands” as well as in many other cultures outside of the African continent. Historically, the migration of people of African descent from their “homelands” is mainly linked to the pre-20th century Muslim or Asian trade and the Atlantic trade as well as to the post 1980 globalization of the capitalist system. Even before the post 1980 globalization of the capitalist system deepened the crises in African states and resulted in the migration of skilled and unskilled Africans to places like the United States, Canada, Britain and the Middle East, some scholars had written on people of African descent in several parts of the world. Although the earliest among those who wrote on the subject before the 1980s did not employ the term “African diaspora” in their analysis, an increasing number of scholars who wrote after 1950 have used the term in question in their study of people of African descent in various parts of the world. The relevant literature written after 1950 features disagreement over the meaning of the concept “African diaspora” and point to diverse methodologies that are useful in working on the subject. This particular literature can be divided into three broad categories: works that deal with the Old African diaspora, works that deal with the New African diaspora and works that deal with both the Old and New African diasporas. The historiography shows that works situated in all of these three categories mainly offer competing view over three fundamental questions: why did Africans leave their “homelands” and settle elsewhere? What was the impact of this process on the societies they left? How did Africans who left their “homelands” integrate into their host societies or preserve their unique identities; or, more broadly, what was the impact of their arrival on the host society they entered? Despite the rapid strides that have been made since the 1960s in regard to addressing these questions or in regards to the scholarly study of the African diasporas in general, there is still no firm definition of the term “African diaspora.” Moreover, there are still other gaps in the scholarly knowledge of the subject.

Over the past six decades, the historiography of Atlantic slavery and the slave trade has shown remarkable growth and sophistication. Historians have marshalled a vast array of sources and offered rich and compelling explanations for these two great tragedies in human history. The survey of this vibrant scholarly tradition throws light on major theoretical and interpretive shifts over time and indicates potential new pathways for future research. While early scholarly efforts have assessed plantation slavery in particular on the antebellum United States South, new voices—those of Western women inspired by the feminist movement and non-Western men and women who began entering academia in larger numbers over the second half of the 20th century—revolutionized views of slavery across time and space. The introduction of new methodological approaches to the field, particularly through dialogue between scholars who engage in quantitative analysis and those who privilege social history sources that are more revealing of lived experiences, has conditioned the types of questions and arguments about slavery and the slave trade that the field has generated. Finally, digital approaches had a significant impact on the field, opening new possibilities to assess and share data from around the world and helping foster an increasingly global conversation about the causes, consequences, and integration of slave systems. No synthesis will ever cover all the details of these thriving subjects of study and, judging from the passionate debates that continue to unfold, interest in the history of slavery and the slave trade is unlikely to fade.
The robust, sustained interest in the history of the transatlantic slave trade has been a defining feature of the intersection of African studies and digital scholarship since the advent of humanities computing in the 1960s. The pioneering work of the Trans-Atlantic Slave Trade Database, first made widely available in CD-ROM in 1999, is one of several major projects to use digital tools in the research and analysis of the Atlantic trade from the sixteenth through the mid-nineteenth century. Over the past two decades, computing technologies have also been applied to the exploration of African bondage outside the maritime Atlantic frame. In the 2010s, (the online successor to the original Slave Trade Database compact disc) joined many other projects in and outside the academy that deploy digital tools in the reconstruction of the large-scale structural history of the trade as well as the microhistorical understandings of individual lives, the biography of notables, and family ancestry.
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.
The use of numerical data and statistical sources in African history has expanded in recent decades, facilitated by technological advances and the digitization of primary sources. This expansion has included new analysis of traditional measures (population, government, and trade) as well as new sources of individual-level data such as census returns, marriage registers, and military and police records. Overall, this work has allowed for a more comprehensive quantitative picture of Africa’s history, and in particular facilitated comparisons within Africa and between African countries and other parts of the world. However, there remain misunderstandings about the collection, use, and interpretation of these data. Increasingly sophisticated methods of quantitative analysis can alienate scholars who have an intimate knowledge of the data and how they are produced, but lack specialist methodological training. At the same time, limited understanding of the origins and reliability of quantitative data can lead to misinterpretation.

The University of Wisconsin-Madison has been a prominent producer of doctorates in African history since 1963. As of 2017 the institution had granted more than 110 degrees. Philip D. Curtin and Jan Vansina, both pioneers in launching the field, led the program until 1975 and were joined in 1969 by Steven Feierman. Together, they supervised an initial cohort of graduates, several of whom became leaders of the then still-formative field, particularly in its methodological infrastructure, as well as in economic and demographic history, slavery in Africa and the Atlantic slave trade, and medical history. The distinguishing features qualifying a diverse array of individual intellectual trajectories as a coherent “school” include a focus on epistemologically historical approaches anchored in the intellectual perspectives of Africans as historical actors and often also as they engaged broader commercial Atlantic and Indian Ocean and world contexts; smaller numbers of more recent doctorates had subsequently sustained these orientations.
Former graduates of the program, William W. Brown, David Henige, and Thomas T. Spear, returned after 1975 to update this framework by bringing social theory and cultural history to bear on the African historical actors at the program’s core. Since 2005, a third generation of faculty members, Neil Kodesh, James Sweet, and Emily Colacci (all students of Wisconsin PhDs teaching at other institutions), have added contemporary approaches to the Wisconsin school’s continuing commitment to Africans’ distinctive epistemologies as they engaged the flows of modern global history. Professionally, Madison graduates have, accordingly, led the ongoing effort to bring Africa in from its initial marginality—as the continent seen as uniquely without a history—into the historical discipline’s core. An aphoristic summary of the Wisconsin legacy might be “Africans’ worlds and Africans in the world.”
