"Four score and seven years ago..."

Novels and poems are not the only form of literature. Perhaps one of the most famous pieces of literature ever written, besides the Declaration of Independence, is the Emancipation Proclamation. The Emancipation Proclamation consists of two executive orders issued by Abraham Lincoln. The first one, issued September 22, 1862, declared the freedom of all slaves in any state of the Confederate States of America that did not return to Union control by January 1, 1863. The second order, issued January 1, 1863, named ten specific states where it would apply. Lincoln issued the Executive Order by his authority as "Commander in Chief of the Army and Navy" under Article II, section 2 of the United States Constitution.

The Emancipation Proclamation was criticized at the time for freeing only the slaves over which the Union had no power. Although most slaves were not freed immediately, the Proclamation did free thousands of slaves the day it went into effect in parts of nine of the ten states to which it applied . In every Confederate state the Proclamation went into immediate effect in Union-occupied areas and at least 20,000 slaves were freed at once on January 1, 1863.

Additionally, the Proclamation provided the legal framework for the emancipation of nearly all four million slaves as the Union armies advanced, and committed the Union to ending slavery, which was a controversial decision even in the North. Hearing of the Proclamation, more slaves quickly escaped to Union lines as the Army units moved South. As the Union armies advanced through the Confederacy, thousands of slaves were freed each day until nearly all were freed by July 1865.

Near the end of the war, abolitionists were concerned that while the Proclamation had freed most slaves as a war measure, it had not made slavery illegal. Several former slave states had already passed legislation prohibiting slavery; however, in a few states, slavery continued to be legal, and to exist, until December 18, 1865, when the Thirteenth Amendment was enacted.
