On Sept. 22, 1862, President Abraham Lincoln issued the preliminary Emancipation Proclamation, declaring all slaves in rebel states should be free as of Jan. 1, 1863. This was no help for Missouri slaves because it was to free slaves located in “states in rebellion” and Missouri was a slave state still in the Union. General John C. Fremont had issued an emancipation order for Missouri slaves on August 31, 1861. President Lincoln immediately enraged abolitionists by rescinding that order. Missouri slaves were not set free by state law until January of 1865.
