Step-by-step explanation:
In September 22, 1862, a presidential proclamation and executive order was made by United States President Abraham Lincoln and it became effective on January 1, 1863.
This Presidential proclamation was called Emancipation Proclamation, or Proclamation 95, was It changed the legal status under federal law of than 3.5 million enslaved African Americans in the Confederate states from slave to free.
The Proclamation was done in the ten states that were still in mutiny in 1863, and thus did not span across the nearly 500,000 slaves in the slave-holding border states like Kentucky, Maryland, Missouri, or Delaware which were Union states. Those slaves were freed by later federal actions and separate state.
