The Oregon Trail played a significant role in the establishment of the boundary between the United States and Canada. The large influx of American settlers and pioneers who traveled along the Oregon Trail in the mid-19th century helped strengthen the U.S.'s claim to the Oregon Territory, which was also being claimed by the British. This ultimately led to the Oregon Treaty of 1846, which established the 49th parallel as the boundary between the United States and Canada in the Pacific Northwest region. The Oregon Trail, therefore, had a direct impact on shaping the boundary between the two countries.
