What is the name of a piece of land bought by the United States in Russia?

A piece of land bought by the United States in Russia is Alaska.

/kloc-At the beginning of the 9th century, the Wicket Indian tribe, who lived in southern Alaska for generations, fought two wars against the invading Russians in succession, and they drove the Russians away in the first war. But in the second war, they were conquered by powerful Russians. Russia was badly hurt in the Crimean War, and Tsar Alexander II was determined to sell this unprofitable land.

Worried that the United States is not interested in buying Alaska, Russia spent $654.38 million to buy some American journalists and politicians, trying to persuade the US government to make a generous acquisition through them. 1867 in March, the Russian trading company sold the occupied land at a price of $4.74 per square kilometer, behind the back of Alaska natives. Despite the opposition of many people in China, US Secretary of State Seward wrote a check for $7.2 million, equivalent to $8.4 billion today. The transaction between the United States and Russia did not hand over the land contract and did not sign the treaty. At that time, no one knew the true value of Alaska, and many Americans criticized Seward for doing a "stupid thing".
