In 1855 how did war between native Americans and miners in Oregon begin?

In 1855, tensions escalated between Native Americans and miners in Oregon due to the influx of settlers and gold seekers encroaching on indigenous lands. The conflict was fueled by the miners' disregard for treaties that guaranteed Native American rights to their territories. Clashes erupted as miners sought to access resources, leading to violent confrontations, most notably the Rogue River Wars. These conflicts ultimately highlighted the broader struggle between U.S. expansion and Native American sovereignty.
