The "Black Star Line" was a shipping line and steamship company established by Marcus Garvey in 1919. Its purpose was to promote the idea of black economic self-sufficiency and to facilitate trade and transportation among black communities around the world. The Black Star Line aimed to create opportunities for black-owned businesses and encourage black people to support and invest in enterprises that would benefit their own communities. It was seen as a symbol of black pride and economic empowerment during the early 20th century.
