lamation provided the legal framework for freeing more than 3 million slaves in those regions. Prior to the Proclamation, in accordance with the Fugitive Slave Act of 1850, escaped slaves were either returned to their masters or held in camps as contraband for later return. The Proclamation applied only to slaves in Confederate-held lands; it did not apply to those in the four slave states that were not in rebellion (Kentucky, Maryland, Delaware, and Missouri, which were unnamed), nor to Tennessee (unnamed but occupied by Union troops since 1862) and lower Louisiana (also under occupation), and specifically excluded those counties of Virginia soon to form the state of West Virginia. Also specifically excluded (by name) were some regions already controlled by the Union army. Emancipation in those places would come after separate state actions and/or the December 1865 ratification of the Thirteenth Amendment, which made slavery and indentured servitude, except for those duly convicted of a crime, illegal everywhere subject to United States jurisdiction.[6]
