by 1827 which two countries were actively claiming the paicific northwest

Question

help meeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Answer 1

I assume Alaska - which was Russian territory until it was sold to the United States in 1867 - is not under consideration in this question.

Great Britain and the United States both claimed the Oregon territory.  The dispute was not settled until 1846, when the border was set at the 49th parallel.
