One of the first members of the new Republican party, he was a delegate to the national organizing convention in Feb., 1856. Barred as a New York delegate to the 1860 Republican convention, because of strained relations with the state leaders, he attended as a representative of Oregon. He was a leader in the successful fight to prevent Seward's nomination; and although at first favoring Edward Bates, he eventually threw his support to Abraham Lincoln. Seward had his revenge later by helping to block Greeley's election to the U.S. Senate (Greeley had served in the House of Representatives from Dec., 1848, to Mar., 1849).
Greeley's course in the Civil War lost him many admirers. At first disposed to let the "erring sisters go in peace," he soon came around to vigorous support of the war. However, he persistently denounced Lincoln's policy of conciliating the border slave states. On Aug. 19, 1862, he published over his signature in the Tribune an open letter to the President, which he titled "The Prayer of Twenty Millions," demanding that Lincoln commit himself definitely to emancipation. Lincoln's reply (Aug. 22) "to an old friend, whose heart I have always supposed to be right" was masterly (see Emancipation Proclamation). Only reluctantly and belatedly did Greeley support Lincoln for reelection in 1864.
The editor's humanitarian hatred of war led him to advocate peace negotiations of any sort, often to the embarrassment of the administration. In 1864, Lincoln sent him on what turned out to be a futile mission to Canada to meet with Confederate emissaries. After the war Greeley favored black suffrage and advocated amnesty for all Southerners. He was one of those who signed the bail bond to release Jefferson Davis from prison, and this magnanimous act cost him half the subscriptions to the Weekly Tribune.
