The goal of this research is to provide a diaspora-centered analysis of Black identity politics by illustrating how African populations navigate their diasporic identities and imposed racial boundaries when engaging with social movements like #BlackLivesMatter. Extending scholarship on Black immigration and Black politics, the present study highlights the processes by which racial histories, U.S. racial hierarchies, and gender hegemony guide African immigrants’ and children of African immigrants’ individual conceptions of Blackness as well as their political engagements. Using a qualitative design (N = 28 semi-structured interviews), I examine first-, 1.5-, and second-generation Africans’ connections to #BlackLivesMatter, a racial justice social movement mobilized in response to the police killings of African American men and women. Findings illustrate that while all participants express an implicit connection to #BlackLivesMatter by drawing attention to the visual aspects of their superordinate Black racial identity, there are certain sources of diasporic fragmentation that lead to racial distancing, intraracial group contention, and subsequent disconnections from the movement. Deconstructing the notion of Black political behavior as homogeneous, findings also suggest that political solidarity does not require uniformity in interests: when engaging in collective action, it is possible to express racial linked fate while also expressing substantial differences in culture and knowledge systems.
