Explain why president lincoln waited for a union victory before announcing the emancipation proclamation.

America’s promise of freedom is filled with contradiction. Perhaps no people understood this more than the roughly four million enslaved African Americans living in the United States before 1863. Through their actions, large and small, enslaved people worked toward the moment of freedom for more than 200 years. On January 1, 1863, the United States government responded. Invoking presidential wartime powers, Abraham Lincoln decreed that all persons held in bondage within the Confederacy were free. The Emancipation Proclamation cracked open the institution of slavery, changing the course of the Civil War and the nation.
