Abraham Lincoln spent the morning of Dec. 31, 1862 meeting with his cabinet to revise the final text of the Emancipation Proclamation, which was due to go into the effect the next day. On the morning of January 1, 1863, after an 11 A.M. reception at the White House, he signed the final, official copy of the document, which had been prepared by the State Department. Frederick Seward, the son of Lincoln’s Secretary of State, was an eyewtiness:
At noon, accompanying my father, I carried the broad parchment in a large portfolio under my arm. We, threading our way through the throng in the vicinity of the White House, went upstairs to the President’s room, where Mr. Lincoln speedily joined us. The broad sheet was spread open before him on the Cabinet table. Mr. Lincoln dipped his pen in the ink, and then, holding it a moment above the sheet, seemed to hesitate. Looking around, he said:
“I never in my life felt more certain that I was doing right, than I do in signing this paper. But I have been receiving calls and shaking hands since nine o’clock this morning, till my arm is stiff and numb. Now this signature is one that will be closely examined, and if they find my hand trembled they will say ‘he had some compunctions.’ But anyway, it is going to be done.”
So saying, he slowly and carefully wrote his name at the bottom of the proclamation. The signature proved to be unusually clear, bold, and firm, even for him, and a laugh followed at his apprehension. My father, after appending his own name, and causing the great seal to be affixed, had the important document placed among the archives. Copies were at once given to the press.
Many abolitionist churches in the North and communities of contraband slaves in Union camps in the South held watch night services on Dec. 31 to await the final proclamation. This year, on the 150th anniversary of the proclamation, some organizations are continuing this tradition, and the document is on exhibit for a limited time at the National Archives.
You can read the final proclamation’s text in the Collected Works of Abraham Lincoln:
Now, therefore I, Abraham Lincoln, President of the United States, by virtue of the power in me vested as Commander-in-Chief, of the Army and Navy of the United States in time of actual armed rebellion against authority and government of the United States, and as a fit and necessary war measure for suppressing said rebellion, do, on this first day of January, in the year of our Lord one thousand eight hundred and sixty three, and in accordance with my purpose so to do publicly proclaimed for the full period of one hundred days, from the day first above mentioned, order and designate as the States and parts of States wherein the people thereof respectively, are this day in rebellion against the United States, the following, towit:
