The primary group that was instrumental in strengthening and saving American claims to Oregon were <u>American missionaries to the Indians.</u>
<u>Explanation:</u>
The Oregon evangelists were pioneers who settled in the Oregon Country of North America beginning during the 1830s committed to carrying Christianity to nearby Native Americans. In 1834 Jason Lee and four partners joined the Wyeth Expedition and set out toward the Northwest.
Lee chose a site in the Willamette Valley, and a strategic built up near present-day Salem, Oregon. The Wyeth-Lee gathering was the primary gathering to venture to every part of the whole course of what was to turn into the Oregon Trail. They additionally gave care and supplies to wagon parties going along the Oregon Trail.
Many whites wanted Indian land, and knew it would be easier to gain if the Indian tribes disappeared. With that statement appeared the Dawes Act, also known as the General Allotment Act, in February 1887. A scheme was soon developed for Indians that would allow individual Indians to own land for private use, and the Indians would be converted into capitalists.
