This changed on September 22, 1862, when President Abraham Lincoln issued a preliminary version of the Proclamation of Emancipation in which he declared that as of January 1, 1863 slaves in those states or parts of the states still in rebellion would be free One hundred days later, Lincoln issued the Emancipation Proclamation declaring that "all persons held as slaves" in the rebel zones "are, and will henceforth be, free."
