Today in History, April 9

146 years ago today, on April 9, 1867, the U.S. Senate passed by a single vote a treaty with Russia to buy Alaska for $7.2 million. Moscow, which wanted to sell the territory, fearing it might lose it in a war with Britain, went on to regret the sale after the Americans found gold there, and many Russians today believe that Alaska rightfully should belong to Russia.
