The Alaska Purchase: U.S. Officially Takes Possession of Alaska from Russia on October 18, 1867
On October 18, 1867, the United States formally took possession of Alaska, marking the completion of the Alaska Purchase from Russia. This significant event, often referred to as “Alaska Day,” reshaped the geographical and economic landscape of the U.S., adding over 586,000 square miles to its territory. The acquisition of Alaska, initially considered “Seward’s Folly,” proved to be one of the most valuable land purchases in American history, given the region’s vast natural resources.
