Friction between the U.S. and Britain over boundary lines in the Louisiana Territory led to heightened tensions and disputes, particularly regarding land claims in the Pacific Northwest and the Oregon Territory. These disagreements contributed to the larger context of U.S. expansionism and manifest destiny, ultimately culminating in the Oregon Treaty of 1846, which peacefully resolved the boundary dispute.

This resolution helped avoid potential conflict and solidified U.S. claims to the Pacific Northwest.
