190 years ago, on April 17, 1824, Foreign Minister of Russian Empire Karl von Nesselrode and US ambassador Henry Middleton signed the first agreement on delimitation of boundaries in Alaska.

According to the document, the border lay along the parallel of 54' 40'' northern latitude. Russians weren't supposed to settle south of that line, Americans — to the north.

In 1867, when Russian Empire had financial difficulties after the Crimean war (1853-1956), Russian part of Alaska was sold to the USA for $7,2 mln.
