Why did Russia and Spain give up on Oregon

Sowwy if im wrong

Explanation:

The Russo-American Treaty of 1824 established a clear border between American and Russian lands on the West Coast as well as trade. It gave Russian claims south of parallel 54°40′ north to the US.

Russia was inclined to give away this territory, which was in dispute between them, Britain, America and Spain, to insure their undisputed and ongoing ownership over Alaska. They were in no position to enforce their claims militarily and the trade value of territories other than Alaska was limited. They decided to get the best agreement that they could to avoid conflict.

A few years later, even Alaska became difficult for them to manage, and, once again fearing losing the land without compensation to either the US or Britain, they negotiated the Alaska purchase.
