Seward’s Day is celebrated on the last Monday in March, which in 2026 falls on March 30. This holiday honors William H. Seward, the U.S. Secretary of State who negotiated the purchase of Alaska from Russia in 1867. Although the purchase was initially ridiculed as “Seward’s Folly,” it later became significant due to the discovery of natural resources, leading to Alaska’s economic growth. The day is recognized as a legal holiday in Alaska, and various events and activities are held to commemorate this historical event. 

William H. Seward played a crucial role in the Civil War intelligence efforts of the Union. As Secretary of State, he was instrumental in coordinating intelligence activities and preventing foreign intervention in the conflict. Seward’s initiative in arresting southern spies and sympathizers, as well as his collaboration with other intelligence officials, helped protect the Union’s capital and maintain control over the war. His efforts were part of a broader effort to gather intelligence and counter espionage, which was essential for the success of the Union’s military operations and the preservation of the nation’s security.
