Caribbean nations such as Cuba, Haiti, and Guyana have historically served as places of refuge for Black Americans escaping racism and political persecution. Pan-Africanists in Guyana had even set up a village for Black Americans. There is also a lengthy history of Black people in the Caribbean protesting against the poor treatment of Black Americans. Artists such as Black Stalin and Mighty Gabby have expressed this in song. Eusi Kwayana was detained by the British colonial government for exposing America's racism against Black Americans.
Of course, this is history that isn't well-known in America because of the disconnect in the Diaspora. We don't know each other's histories like we should. If we did, we'd understand how interconnected our struggles have always been.
When has the “diaspora” helped Black America?
