Question

How was the addition of Oregon to the United States an example of the idea of manifest destiny

Answer 1

Manifest Destiny was used to validate the acquisition of Oregon.

Three absolute beliefs were, and continue to be, attached to this idea of Manifest Destiny:

1. Americans would geographically, politically, and economically expand to the continental limits.
2. Americans would Americanize all people living within the continental limits.
3. Americans would conquer both the people who resisted Americanization and the natural geographical forces that stood in their way.
