Desire for expansion: The United States had long been interested in expanding its territory, particularly in the Pacific Northwest. Alaska was seen as a valuable addition to the country, providing access to natural resources such as gold, timber, and fur, as well as strategic military advantages.
The influence of William H. Seward: U.S. Secretary of State William H. Seward was a strong advocate for the purchase of Alaska. He believed that it was a wise investment that would benefit the United States in the long run. Seward also argued that acquiring Alaska would improve relations with Russia and reduce the risk of conflict between the two countries.
