Concept note-1: -President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863, as the nation approached its third year of bloody civil war. The proclamation declared “that all persons held as slaves” within the rebellious states “are, and henceforward shall be free."
Concept note-2: -Fact #9: The Emancipation Proclamation led the way to total abolition of slavery in the United States. With the Emancipation Proclamation, the aim of the war changed to include the freeing of slaves in addition to preserving the Union.
Concept note-3: -The Proclamation changed the legal status of more than 3.5 million enslaved African Americans in the secessionist Confederate states from enslaved to free.
