As an activist and writer, Domingo travelled to the United States advocating for Jamaican sovereignty as a leader of the African Blood Brotherhood and the Harlem branch of the Socialist Party.
In 1913, Domingo embarked on a speaking tour to various places in the United States where he discussed his vision for reform and progress in Jamaica.
[3] For that reason, Domingo was forced to resign as editor of the newspaper, but continued to write for the Black socialist press.
Domingo's essay "The Gift of the Black Tropics" gave an account of the sudden immigration of foreign-born Africans of the West Indies to Harlem during the early 1920s.
The League's most basic aims included establishing Jamaican self-governance, universal suffrage, and the right to form labour unions.
They also encouraged their countrymen to study Jamaica's history and art in order to foster the desire for people to express themselves and their culture artistically.
[3] Taken from The Messenger, Domingo presents an argument in which he favours the racial descriptor of "Negro" over "Colored" in describing an individual of African descent.
[5] He characterized the foreign-born Harlem population, of which he was a part, as frugal, hard-working, and refusing to conform to the ways of native-born Black Americans.
Additionally, Domingo compared foreign- and native-born Black folks in terms of their political and religious beliefs, contributions to the Harlem community, and feelings surrounding the color line.
This essay situates how the intersections of racism, colorism, sexism, classism, and xenophobia affected the lives of Harlem's Black population in the 1920s.
