How does the method of Political Black Nationalism work?

Black nationalism is a type of nationalism or pan-nationalism which espouses the belief that black people are a race and seeks to develop and maintain a black racial and national identity.[1] Black nationalist activism revolves around social, political, and economic empowerment of black communities and people, especially to resist assimilation into white culture (through integration or otherwise) and maintain a distinct black identity.[1]

Explanation:

Black nationalism arose within the African American community in the United States. In the early 20th century, the Garveyism promoted by the U.S.-based Marcus Garvey furthered black nationalist ideas. Black nationalist ideas also proved an influence on the Black Islam movement, particularly groups like the Nation of Islam founded by Elijah Muhammad. During the 1960s, Black nationalism influenced the Black Panther Party and the broader Black Power movement

imperialism is a type of government that seeks to increase its size, either by forcing (through war) or influencing (through politics) other countries to submit to their rule. the sun never sets on the roman empire, or so went the saying when rome controlled the majority of europe 2000 years ago.
