Lincoln used the Emancipation Proclamation as a war weapon during the Civil War. This will allow the freedom of the slaves belonging to the states against the country’s union, most of them the southern ones, taking out their main source of production of their agriculture. Consequently, the free black people joined to the army of the states that support the Union showing Lincoln’s power as a commander of the army. He did not free the slaves of all the states because the supportive states used slavery as a force of work, besides that he argued that the black people were not equal to the white ones, they were just for work. Taking out slavery in the enemies will be a low point to them to take advantage, if they took out slavery in their own states, they would have been weak as well.
