Africa and Its Diasporas under Slavery  

Walter Hawthorne

Diasporas result when people from the same place, real or imagined, migrate to another place, settle together, and produce new generations. African diasporas before 1900 resulted from forced migrations, spurred by the trade in enslaved people from the continent into the Atlantic and Indian Oceans, Red Sea, and across the Sahara Desert. The identities that Africans in diasporas professed and cultures that they created and recreated differed across time and space. Among the things that shaped African diasporic cultures were the nature of linkages to African homelands and the political, economic, religious, and social structures of the broader societies in which African diasporas were situated. These and other factors meant that African diasporas in Indian Ocean societies were very different from those in Atlantic Ocean societies. Generally, over time enslaved Africans in diaspora around the Indian Ocean sought to become part of broader cosmopolitan communities and did not associate themselves with an African homeland. Enslaved Africans in diaspora around the Atlantic Ocean built communities that were apart from those of their enslavers and identified with African homelands. However, in some periods, societies with slaves in the Americas offered opportunities for enslaved people to become part of dominant institutions, and some enslaved people could take advantage of those opportunities to forge new lives for themselves and others. Everywhere African diasporas formed, those people who composed them shaped local and global histories in ways that are evident today.

Ideological and Technological Exchanges in the Early Modern Atlantic  

Walter C. Rucker

Despite assumptions regarding the unidirectional flow of ideas and technologies from Europe to Atlantic Africa beginning in the 1440s, African-European interactions were far more complex and dynamic. The multilateral flow of concepts in the early Atlantic world had a precedent in the Mediterranean world. New and reintroduced concepts entering Iberia from North Africa and Arabia propelled sustained contacts between Europe, Africa, and the Americas. Beginning with the Umayyad Caliphate’s conquest of Iberia until the defeat of the last Islamic stronghold in 1492, Iberian architecture, language, and science received waves of innovation from foreign sources. This constant cross-fertilization reintroduced Iberians and other Europeans—emerging from the early Middle Ages—to physics, astronomy, and geometry; navigational instruments like compasses, quadrants, and astrolabes; and seafaring technologies like lateen sails. This process of multilateral exchange and interaction set the stage for the complex engagements between Europeans and Atlantic Africans by the mid-15th century. Beginning with the Portuguese in the 1440s, Europeans engaged with Atlantic Africans and, together, developed commercial networks, political alliances, and social connections from Senegambia to Angola. Within these regions, a matrix of exchanges occurred that shaped the course of Atlantic history. Above and beyond the Columbian Exchange of agricultural products, Atlantic Africans introduced Europeans to an array of aquatic proficiencies; techniques associated with mineral extraction, mining and metallurgy, and crop cultivation; and herblore. Instead of understanding Atlantic Africa as a recipient of foreign ideas and innovations and in a state of dependency, communities in the region were partners within the many exchange networks through the 18th century. As they absorbed, internalized, and—in some cases—Africanized European ideas and technologies, Atlantic Africans also introduced Europeans to African innovations. As vectors of Atlantic African and Atlantic creole ideas, enslaved women and men fueled a broader range of exchanges in Western Hemisphere colonies.
