FACT: President Abraham Lincoln proposed ending slavery by 1900; the 13th Amendment could have been far different had Congress done what Lincoln proposed.
This is from his Address to Congress December 1, 1862...
“... In this view, I recommend the adoption of the following resolution and articles amendatory to the Constitution of the United States: “Resolved by the Senate and House of Representatives of the United States of America in Congress assembled, (two thirds of both houses concurring,) That the following articles be proposed to the legislatures (or conventions) of the several States as amendments to the Constitution of the United States, all or any of which articles when ratified by three-fourths of the said legislatures (or conventions) to be valid as part or parts of the said Constitution, viz:
“Article -—.
“Every State, wherein slavery now exists, which shall abolish the same therein, at any time, or times, before the first day of January, in the year of our Lord one thousand and nine hundred, shall receive compensation from the United States as follows, to wit:
“The President of the United States shall deliver to every such State, bonds of the United States, bearing interest at the rate of -— per cent, per annum, to an amount equal to the aggregate sum of for each slave shown to have been therein, by the eig[h]th census of the United States, said bonds to be delivered to such State by instalments, or in one parcel, at the completion of the abolishment, accordingly as the same shall have been gradual, or at one time, within such State; and interest shall begin to run upon any such bond, only from the proper time of its delivery as aforesaid. Any State having received bonds as aforesaid, and afterwards reintroducing or tolerating slavery therein, shall refund to the United States the bonds so received, or the value thereof, and all interest paid thereon...”
You are absolutely correct. Had everyone simply done what Lincoln proposed, Slavery would have lingered way longer than 1900.
The Ghost Amendment that haunts Lincoln's Legacy.
I bet you didn't know that Lincoln was pushing an Amendment to make slavery continue indefinitely.
