“Although there were enslavers who were aware of the implementation of the Emancipation Proclamation, it wasn’t until June 19, 1865, that it was actually enforced [by] the Union Army,” writes Mary Elliott, curator of American slavery at the Smithsonian’s National Museum of African American History and Culture (NMAAHC) in a blog post. “... It took the creation of the Emancipation Proclamation, the end of the Civil War, and the passage of the 13th Amendment to finally end slavery throughout the nation.”
