Who was the U.S. Secretary of State that purchased Alaska from Russia?

The purchase of Alaska from Russia in 1867 was negotiated by William H. Seward, who was the U.S. Secretary of State at that time. Seward played a crucial role in advocating for the acquisition, believing it would enhance American territory and economic interests. The transaction is often referred to as "Seward's Folly" by skeptics who questioned the value of the purchase, given that Alaska was largely viewed as a barren wasteland. However, Seward believed in the strategic and resource potential of Alaska, which ultimately proved to be a significant and beneficial acquisition for the United States, rich in natural resources such as gold, oil, and fish.

The other historical figures listed were instrumental in different periods of American history. Thomas Jefferson, for example, is known for the Louisiana Purchase, while John Quincy Adams and James Monroe were prominent in the era of early American diplomacy and expansion, but neither was involved in the acquisition of Alaska.
