Question

What was the Impact of Westward movement in USA.

Answer 1

Westward expansion, particularly west of the Mississippi River, had profound effects on American politics. The Monroe Doctrine set forth a policy of Manifest Destiny that the United States should extend from the Atlantic Coast to the Pacific Coast. This expansion created a number of political crises that revolved around the expansion of slavery, dispossession of Native Americans and federal landholdings in the West.
