On March 2, 1861 A bill was passed by the Senate which proposed an amendment to the US Constitution. Here is the text:
"No amendment shall be made to the Constitution which will authorize or give to Congress the power to abolish or interfere, within any State, with the domestic institutions thereof, including that of persons held to labor or service by the laws of said State."
Basically, what the amendment proposed to do was prevent Congress from interfering with the institution of slavery, in the States that it existed in.
Two days later in his inaugural address, Lincoln made the following remarks:
""I understand a proposed amendment to the Constitution has passed Congress, to the effect that the Federal Government
shall never interfere with the domestic institutions of the States,
including that of persons held to service. Holding such a
provision to now be implied constitutional law, I have no
objection to its being made express and irrevocable."
The amendment was never ratified by the Constitutionally required 3/4 of the States. However, what is important is that Lincoln expressly endorsed the amendment, an amendment which would prevent the federal government from interfering with slavery.
If the South only wanted to "keep their slaves", then all they had to do was to stay within the Union.
This exposes the myth that the "Civil War was fought over slavery", as the politically correct lie that it is."
