The initial push for a federation among British Caribbean colonies might have originated among the white elites, but the banner for federation was quickly picked up by Afro-Caribbean activists who saw in the possibility of a united West Indian nation a means of securing political power and more.

In Building a Nation, Eric Duke moves beyond the narrow view of federation as only relevant to Caribbean and British imperial histories. By examining support for federation among many Afro-Caribbean and other black activists in and out of the West Indies, Duke convincingly expands and connects the movements history squarely into the wider history of political and social activism in the early-mid-twentieth century Black Diaspora.

Exploring the relationships between the pursuit of Caribbean federation and Black Diaspora politics, Duke posits that federation was more than a regional endeavor; it was a diasporic, blacknation building undertakingwith broad support in diaspora centers such as Harlem and Londondeeply immersed in ideas of racial unity, racial uplift, and black self-determination.
