Answer 1

The U.S manifest destiny was the belief that it was the destiny and duty of Americans to expand the United States from coast to coast. This was used to justify annexations and acquisitions of territories.

Step-by-step explanation:

The U.S manifest destiny was a belief held by many Americans in the mid-19th century that it was their destiny and duty to expand the United States from coast to coast. They saw this expansion as inevitable and divinely ordained. The concept of manifest destiny was used to justify the annexation of Texas and Oregon, as well as the acquisition of territories from Mexico, including California, through the Mexican-American War.
