What was the events of manifest destiny of 1840?

Answer 1

Manifest Destiny, a term popularized in the 1840s, encapsulated the belief that the United States was destined to expand across the North American continent. Key events during this period included the annexation of Texas in 1845, which led to tensions with Mexico, and the subsequent outbreak of the Mexican-American War (1846-1848). The war resulted in significant territorial gains for the U.S., including present-day California, Arizona, New Mexico, and parts of Colorado, Nevada, and Utah, further fulfilling the ideology of westward expansion. This period also fostered a sense of American exceptionalism and led to conflicts with Indigenous peoples and other nations.
