What did Adams onis treaty have to do with the Oregon country?

The Adams-Onís Treaty of 1819, also known as the Transcontinental Treaty, established a boundary between Spanish territory and the United States, which included provisions related to the Oregon Country. While the treaty primarily focused on ceding Florida to the U.S. and defining the boundary between Spanish Mexico and the U.S., it effectively recognized U.S. claims to the Oregon region by clarifying territorial boundaries. This laid the groundwork for further American interest and eventual settlement in the Oregon Country in the following decades.
