Answer: The Emancipation Proclamation freed slaves, but only those in Southern States. The 13th Amendment expanded the abolishment of slavery to the North as well as involuntary servitude in both the North and South. Among other things the 14th Amendment established the equal legal protection of all citizens born or naturalized in the United States.
In the end the 14th Amendment was little more than a reiteration of the "all men are create equal" phrase in the Declaration of Indendence, which was originally called 'the true Bill of Rights'. The 'men' in the famous phrase referred to all Mankind, including women as well as slaves of any of the races.
