The Alaska Purchase was the purchase of Alaska by the United States from the Russian Empire in 1867. The purchase, made at the initiative of United States Secretary of State William H. Seward, gained 586,412 square miles (1,518,800 km2) of new United States territory. Originally organized as the Department of Alaska, the area was successively the District of Alaska and the Alaska Territory before becoming the modern state of Alaska upon being admitted to the United States in 1959.
After sweeping the elections of 1866, the Radical Republicans gained almost complete control over policymaking in Congress. Along with their more moderate Republican allies, they gained control of the House of Representatives and the Senate and thus gained sufficient power to override any potential vetoes by President Andrew Johnson.
