The Declaration of Independence had nothing to do with freeing any slaves. You are probably thinking of the Emancipation Proclamation in which Lincoln ordered that slaves be freed in any Confederate state that did not return to the Union by January 1, 1863. The Proclamation did not cover any slaves in Union states.
There weren't any slaves after the american civil war. They were freed by the emancipation act.
Yes, in Africa
It technically freed the slaves in the states in rebellion, but not the ones in the Border states that had stayed loyal. In practice, it did not free many slaves, but the Union troops were licensed to liberate any slaves they came across in their Southern campaigns. These presently joined the Union armies.
The Emancipation Proclamation
The 13th Amendment, December 1865. Lincoln's Emancipation Proclamation of January 1863 did not directly free any slaves, except that it licensed Union troops to free any slaves they came across.
Civil war Union generals and there troops went to go kill any plantation owners in the area with slaves.
While the 13th amendment freed the slaves, it did not make them citizens or give them any rights. The newly freed slaves had no where to go after the 13th amendment was passed -- they were simply no longer slaves. Most slaves during the civil war had been born into slavery as the importation of slaves was made illegal in 1808. So, the slaves had no reason to go back to Africa, as they had no money and many had never been there anyway. The U.S. government realized they had to do something about all these people, so they essentially gave them citizenship with the 14th amendment, and later the right to vote with the 15th.
The man freed slaves. Thats a major one right there.
On his death bed he freed a Tarter slave that may have accompanied him from Asia.
The Emancipation Proclamation freed the slaves in the Southern states, who already broke off from the union. This meant that President Lincoln had no control over whethere these slaves would be free or not. But once a Southern town or area was freed by Union soldiers, the slaves would be free. This caused help for the Union army from former slaves. The Emancipation Proclamation went into effect January 1, 1863.
The black slaves were freed and there wasn't any more slavery in the north or the south.
