Wheat documents how forced migrants from African functioned as "de facto colonists." The book added detail and nuance to my understanding of the early modern Atlantic world. Ibero-African creolized cultures existed on both sides of the Atlantic c. 16oo. Many Africans trafficked as slaves to the Spanish Caribbean arrived with some Iberian cultural knowledge. Moreover, these forced migrants often also retained specific ethnic identities from Africa. These identities were also known to many Iberians, both in Africa and in the Caribbean. The large scale slave societies, especially those based on sugar production, evolved later. As always historians need to remember not to project the most salient aspects of past further back than the evidence supports.
"[E]nslaved workers...performed tasks that in Spain would have been done by Iberian agricultural workers...The extensive participation of sub-Saharan Africans in Spain's colonization of the circum-Caribbean created an economically and socially diversified population that does not resemble models of later monoculture slave systems. At the same time, that most of these de facto colonists arrived as involuntary migrants on slave ships makes their participatory roles far more ambiguous than those of voluntary migrants performing similar labors in other settings" (160).
