The correct answer to this open question is the following.
Although the question is incomplete because it does not refer to a specific moment or place in the history of the US, we can say that if it refers to President Abraham Lincoln's Emancipation Proclamation of 1863, then his new freedom was 'inconceivable" to African Americans in the southern states until the Union Army won the American Civil War in 1865. However, although the ratification of the 13th Amendment to the Constitution of the United States happened in December 1865, the road to freedom for African Americans in the south was long to come. During Reconstruction, Jim Crow Laws and the Black Codes were southern legislations that limited freedom and the civil rights of Black people.
