My family went to the movies to see "Lincoln," the much advertised and critically acclaimed new film by Steven Spielberg. The plot centered on one particular phase of the president's legacy, the abolition of slavery and how he got it done. All of us were taught the Emancipation Proclamation was the vehicle that abolished slavery in America. That just is not true, and Spielberg brilliantly showed us the real story. That's right, it was not the Emancipation Proclamation!
Wikipedia: "The Emancipation Proclamation is a military order issued to the Army and Navy of the United States by President Abraham Lincoln on January 1, 1863, during the American Civil War. It was based on the president's constitutional authority as commander in chief of the armed forces; it was not a law passed by Congress. It proclaimed all slaves in Confederate territory to be forever free; that is, it ordered the Army to treat as free men the slaves in 10 states that were still in rebellion, thus applying to 3.1 million of the 4 million slaves in the U.S."
Lincoln knew that this was flimsy and would probably fall apart at the end of the war. The Confederacy certainly would use this as a condition of surrender (to keep slavery) and the American people were so weary of the war which terribly affected every household with death and misery. This was simply an executive order implemented under the War Powers Act. It didn't even apply to non-Confederate states, and the Confederate states paid no attention to it at all. What he needed was an amendment to the Constitution. Thus, he had his Republican Party sponsor the bill which would become the 13th Amendment. This amendment would outlaw slavery within the United States forever.
Although the abolition of slavery was part of the main platform of the new Republican Party, it wasn't going to be easy at all. An amendment to the Constitution must have two-thirds of the House votes to pass and go onto the president's desk. The Republicans had a majority, but were not even close to a two-thirds majority. In addition, the Democratic Party was very much against the thought of abolishing slavery. They certainly were going to dig in and try to defeat the amendment. The GOP needed 22 Democratic votes to pass the bill, and so the plot thickened. Time was "ticking" as the amendment needed to be passed before the end of the war. Congress would be in no mood to stir up things again with a new initiative against slavery.
Lincoln and various GOP House leaders had to come up with a political scheme to rid America of slavery. Spielberg did more than clearly show how ugly politics can be. Lincoln, the congressmen, cabinet officials, Gen. Grant, lobbyists, press, etc., were all involved in this ebb-and-flow struggle.
Patronage jobs, earmarks, bribery, etc. were some of the "ammunition" that was used in the persuasion of certain Democrats. "Honest Abe" was not totally honest in this struggle to make his dream a reality--the abolition of slavery--but he got the job done.
