Following the Adam onis treaty which country clamied the Oregon territory?

Following the Adams-Onís Treaty in 1819, the United States and Spain settled territorial disputes, with Spain relinquishing its claims to the Oregon Territory. Consequently, the U.S. asserted its claim over the Oregon Territory, which was initially jointly occupied by both the U.S. and Britain under the 1818 treaty. This set the stage for future negotiations and conflicts over the territory, culminating in the Oregon Treaty of 1846.
