An Historic Irony

Yes, I am one of the people who say "an historic".

So I'm reading for my law history class and I came across this ironic case in US History. Not a legal case, just a case of fact.

The 13th amendment to our constitution ratified in 1865 reads:

1. Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.


2. Congress shall have power to enforce this article by appropriate legislation

In 1860 then senator Jefferson Davis (later head of the Confederate States of America) proposed the following 13th amendment which was NARROWLY kept from passing due to Lincoln's election and the secession of the southern states:

Neither Congress nor a territorial legislature...possess the power to annul or impair the constitutional right of any citizen of the United States to take his slave property into the common territories..."
 
...Funny how one election and 5 years made such a difference.
