The UNIA was formed by Marcus Garvey in 1913. His goal was to promote the welfare of Black communities. He argued that Black people would be better off strengthening their own communities and businesses. In New York City, the UNIA provided Black history classes and job training, and advertisements for Black-owned businesses.
The NAACP was formed by W.E.B Du Bois and a group of activists in 1909. Their goal was to ensure political, educational, social and economic equality in the United States. Allowing equality among the races. They fought to stop discriminaiton and violence and to secure voting rights.
One of the UNIA’s goals was to transport Blacks back to Africa using the Black Star Line as they believed equality would not be achieved in the United States. However the shipping company was never completed and Garvey was deported to Jamaica, his native land. Because of this, this makes the NAACP more successful, though UNIA was influential to the advancement of Black Nationalism.
