The Civil War, a war fought during the 1860s, decided a great many things: slavery or freedom, south and north or unification. In the beginning of the war, the Northern African Americans were not allowed to join the Union Army and fight against the Southern oppressors. Alfred M. Green, while giving a speech in Philadelphia at the beginning of the war, urged African American to prepare to enlist. He also spoke subversively about the unfairness of the treatment of African Americans not only in the South but also in the North. Green uses a variety of methods to persuade his fellow African-Americans to prepare for war while also speaking out against the treatment of the African-Am. in the North.
