The U.S. purchased Alaska in 1867. At the time the purchase was called "Seward's Folly" and "Seward's Icebox", the name in honor of the Secretary of State. My guess is that the natural rival purchaser would have been Hudson Bay Company, since Britain declared Canada independent around the same time. Canada's Dominion Day in fact is July 1, 1867. Hudson Bay Company later sold Rupert's Land to the Dominion of Canada for $1,500,000.00. I doubt that Russia would have held it; Russia needed the cash badly.
