The Emancipation Proclamation created the legal framework for the liberation of the vast majority of the South's slaves during the course of the war. There were about 3.5million slaves living in the Southern states, excluding the border states that did not secede, in 1860. The Proclamation famously exempted the border states as well West Virginia, twelve parishes of Louisiana, seven counties in the rest of Virginia or to Tennessee. With the various exemptions of the Proclamation considered, the estimate given is usually that 3.1million persons - a little over three-quarters of the total slave population of the entire South - were legally granted freedom as a result of the Proclamation. The 1860 census records only around 432,000 enslaved persons living in Delaware, Missouri, Kentucky, Maryland or Washington D.C.; a comparable number again were made exempt by provisions relating to other states (Virginia, Louisiana and Tennesse had 1.1million slaves between them in 1860).
