What British in 1846 signed the Oregon Treaty what happened afterwards?

In 1846, the Oregon Treaty was signed between the United States and Great Britain, resolving the Oregon boundary dispute by establishing the 49th parallel as the border between British North America and the U.S. west of the Rocky Mountains. After the treaty, the Oregon Territory was officially organized, leading to an influx of American settlers in the region. This expansion contributed to the westward movement and settlement patterns that characterized the United States in the following decades. The peaceful resolution of the Oregon boundary dispute also set a precedent for future territorial negotiations between the two nations.
