Marcus Garvey founded the Universal Negro Improvement Association (UNIA) in 1914 in Jamaica (his native country). In 1916, Garvey moved to New York City and the UNIA activity became centered there. In 1919, Garvey also started the Black Star Line, which was a shipping & distribution line dedicated to the economic success of the black community. A 1920 business meeting of the Black Star Line brought together 25,000 delegates of the UNIA from around the world in Harlem, New York. At that meeting, the Declaration of Rights of the Negro Peoples of the World was produced.
The Declaration began with a list of 12 complaints of the black community, which concluded with the statement, "Against all such inhuman, unchristian and uncivilized treatment we here and now emphatically protest, and invoke the condemnation of all mankind." Then the Declaration listed 54 principles of rights asserted by the UNIA, of which the quoted line above is principle #3.
