Early Career
Seward served in the New York State Senate from 1831 to 1834, as the 12th governor of New York from 1839 to 1842, and as a U.S. senator from New York from 1849 to 1861 [1].
Secretary of State
He served as the 24th U.S. Secretary of State from 1861 to 1869 under Lincoln and Johnson. He was praised for Civil War diplomacy that helped deter Britain and France from recognizing the Confederacy. In 1865 he was wounded in the plot that killed Lincoln, and his wife, Frances, died that year [1].
The Alaska Purchase
Seward negotiated with the Russian diplomat Eduard de Stoeckl. The treaty was signed at 4:00 a.m. on March 30, 1867, after an all-night session in Washington. The price was $7.2 million, about two cents per acre, and the Senate ratified it on April 9, 1867, by a vote of 37 to 2. U.S. sovereignty took effect on October 18, 1867, at a ceremony in Sitka [2].
Why Russia Sold
Russia had lost the Crimean War, found its Alaskan colony hard to defend against Britain, saw its sea otter population collapse and needed money [2]. See the entry on the Treaty of Cession.
Seward’s Folly
Critics called the purchase “Seward’s Folly” and “Seward’s Icebox,” arguing the United States had bought useless land. The 586,412-square-mile territory later proved valuable for its fish, gold, timber and oil [2].
Later Years and Legacy
Seward supported Johnson during Johnson’s impeachment and was nicknamed the Sage of Auburn. He died on October 10, 1872, in Auburn, New York, aged 71 [1]. The Alaska city of Seward, the Seward Peninsula and the Seward Highway bear his name. See also the entries on the Alaska Purchase and the Territory of Alaska.
