The presence of Africans in Asia and their migration around it is one of the least-studied subjects in all of Asian history. The same is true for studies of the African diaspora, but that does not mean that African migration lacks significance in either field. Existing scholarship reveals that Africans traveled to and settled in various regions in Asia, from the Arabian Peninsula to Nagasaki. While there were free African migrants in Asia, a larger number of them arrived as slaves, transported there by both local and European traders. Conditions for the forced immigrants varied and not all of them remained permanently un-free, with some even eventually coming to obtain political power. To understand their dispersal and presence in Asia does more than simply broaden our current understanding of the African diaspora; it also enables us to understand that the African diaspora is a global phenomenon. That improved understanding can in turn break down the geographical boundary of Asian history and connect it not only to African history but to European history too. To do that, the topic requires scholars to challenge the methodological limits of current historical studies.
