Explain why the number of U.S. settlers helped to finalize the border between the U.S. and Britain in the Pacific Northwest (PNW). (DO NOT USE SOURCES) (Make sure it is three SHORT sentences.)

Answer 1

The increasing number of U.S. settlers in the PNW put pressure on the U.S. government to solidify its border with Britain to prevent further disputes. The settlers demanded protection and clarity on land ownership rights, prompting the U.S. government to negotiate and establish the Oregon Treaty in 1846. This treaty ultimately divided the PNW into British and American territories along the 49th parallel.
