Which country did Hawaii belong to before it was sold to the United States?

It seems that Hawaii was not sold. It turned out that the locals lived there, and later they wanted to submit to the United States and become the 50th state of Hawaii.

The most famous state that was sold was Alaska. The U.S. government bought it from the Tsar for $720 (the currency value at that time, I don’t know how much it is now). It was later considered to belong to the Tsarist government. Big mistake.
