Alaska Purchase

1867 sale by Russia to the United States

The Alaska Purchase in 1867 resulted in the transfer of Russian America to the United States for $7.2 million (equivalent to $132 million in 2024). On April 9 of that year, the United States Senate ratified a bilateral treaty that had been signed on March 30, and American sovereignty became legally effective across the territory on October 18. During the first half of the 19th century, the Russian Empire had established a colonial presence in parts of North America, but few Russians ever settled in Alaska.
