The Oregon missionaries were collectively the religious-minded pioneers who settled in the Oregon Country of North America starting in the 1830s with the intent of converting local Native Americans to Christianity.[1] The Foreign Mission movement was already 14 years underway by 1820, but it was difficult to find missionaries willing to go to Oregon, as many wanted to go to the east, to India or China.[1] It was not until the 1830s, when a schoolmaster from Connecticut, Hall Jackson Kelley, created his "American Society for the Settlement of the Oregon Country," that more interest and support for Oregon missionaries grew.[1] Oregon missionaries played a political role, as well as a religious one, as their missions established US political power in an area in which the Hudson’s Bay Company, operating under the British government, maintained a political interest in the Oregon country.[2] Such missionaries had an influential impact on the early settlement of the region, establishing institutions that became the foundation of United States settlement of the Pacific Northwest.

It is meant that like tapestry scientific theories often need to pull out since they are not relevant and often times the whole chain of theories may be pulled out.
