This essay argues that Marcus Garvey held a constructivist theory of self-determination, one that saw nationalism and transnationalism as mutually necessary and reinforcing ideals. The argument proceeds in three steps. First it recovers Garvey’s transnationalist emphasis by looking at his intellectual debts to other diaspora struggles, namely political Zionism and Irish nationalism. Second it argues that Garvey held a constructivist view of national identity, which also grounds his argument that the black diaspora has a right to collective self-determination. Third it (...) explicates Garvey’s further contention that the right to self-determination and the persistence of oppression give the African diaspora a pro tanto claim to an independent state, which he considered essential to vanquishing white supremacy and realizing collective self-rule.
