The acquisition of the Oregon Territory was not a result of the United States' victory in the Mexican-American War; instead, it was obtained through a peaceful settlement with Great Britain. Key outcomes of the Mexican War included territorial expansion, disputes over slavery extension, potential party splits, and increased settlement in areas like California.
- The victory of the United States in the Mexican-American War resulted in significant consequences, but the acquisition of the Oregon Territory is not one of them.
- The correct outcomes of the war included the cession by Mexico of an enormous amount of land to the United States, which included present-day California, Nevada, Utah, and parts of Arizona, Colorado, New Mexico, and Wyoming.
- This subsequently led to renewed controversy over the issue of extending slavery into the territories, a situation that could potentially split the Whig and Democrat parties over the slavery question, and a rush of settlers to the new American territories, notably seen with the California Gold Rush.
- The acquisition of the Oregon Territory was actually achieved through negotiations with Great Britain and not as a result of the Mexican-American War.
- Therefore, the correct answer to the question is the acquisition of the Oregon Territory, as it was not a direct consequence of the United States' victory in the Mexican War.
