Link to Emancipation Proclamation ---Emancipation Proclamation
Quote from below Emancipation Proclamation ---"On Jan. 1, 1863, U.S. President Abraham Lincoln declared free all slaves residing in territory in rebellion against the federal government. This Emancipation Proclamation actually freed few people. It did not apply to slaves in border states fighting on the Union side; nor did it affect slaves in southern areas already under Union control. Naturally, the states in rebellion did not act on Lincoln's order."
If you want to consider over 3 million people "few", I suppose you could say that. Two million was CSA president Jefferson Davis' estimate of confederate states slaves freed as of September of 1864, only 18 months after the EP was issued. Naturally, states in rebellion did not follow Lincoln's order. But the United States Army did follow it, and they enforced it so well that by June 19 of 1865, (Juneteenth day in Texas) there were no slaves left in areas that were in rebellion as of Jan of 1863. All told, over 3 million slaves were liberated by the EP.
