俄國沙皇亞歷山大二世，依當年俄國駐美公使Eduard de Stoeckl和美國國務卿William H. Seward斡旋後，1867年3月30日所簽訂之條約，以美金720萬元代價，將阿拉斯加賣給美國政府。在條約生效前，阿拉斯加原來是俄國拓殖未完成的殖民地。
1. Russian Colonization on Alaska
Some researchers believe that the first Russian settlement in Alaska was established in 17th century.
Sitka, renamed New Archangel from 1804 to 1867, on Baranof Island in the Alexander Archipelago in what is now Southeast Alaska, became the capital of Russian America and remained the capital after the colony was transferred to the United States. The Russians never fully colonized Alaska, and the colony was never very profitable.
William H. Seward, the United States Secretary of State, negotiated the Alaska Purchase (also known as Seward's Folly) with the Russians in 1867 for $7.2 million. Alaska was loosely governed by the military initially, and was administered as a district starting in 1884, with a governor appointed by the president of the United States, as well as a district court headquartered in Sitka.
2. Alaska Purchase Treaty
The Alaska Purchase was the acquisition of the Alaska territory by the United States from Russia in the year 1867 by a treaty ratified by the Senate.
The Russians therefore started to believe that in any future conflict with Britain, their hard-to-defend region might become a prime target, and would be easily captured. Therefore the Tsar Alexander II decided to sell the territory.
Following the Union victory in the Civil War, the Tsar then instructed the Russian minister to the United States, Eduard de Stoeckl, to re-enter into negotiations with Seward in the beginning of March 1867. The negotiations concluded after an all-night session with the signing of the treaty at 4 a.m. on March 30, 1867, with the purchase price set at $7.2 million, or about 2 cents per acre.
3. Alaska Status
Alaska was purchased from Russia on March 30, 1867, for $7.2 million ($113 million in today's dollars) at approximately two cents per acre ($4.74/km²). The land went through several administrative changes before becoming an organized (or incorporated) territory on May 11, 1912, and the 49th state of the U.S. on January 3, 1959.
