Manifest Destiny was a 19th-century doctrine or belief that the expansion of the United States across the American continents was both justified and inevitable. This ideology emerged in the 1840s and became a foundational aspect of American nationalism, underpinning the United States’ territorial expansion.
### Key Elements of Manifest Destiny:
1. **Divine Right**: Proponents believed that it was America's God-given right to expand its territory across the continent from the Atlantic to the Pacific Ocean.
2. **Cultural Superiority**: Many adherents held the view that American democratic values and way of life were superior and that it was their duty to spread these values to what they considered "less developed" territories and peoples.
3. **Economic Opportunity**: Expansion was also linked to the idea of economic opportunity, as more land meant more resources, agriculture, and wealth for the increasingly growing population.
### Effects on the Size of the United States:
1. **Territorial Acquisition**: The policy of Manifest Destiny significantly contributed to the territorial expansion of the United States. Notable instances include:
- **The Louisiana Purchase (1803)**: Doubled the size of the U.S. and set a precedent for further expansion.
- **Annexation of Texas (1845)**: Texas was an independent republic that was incorporated into the United States, which led to a war with Mexico.
- **Oregon Trail and the Oregon Territory**: The desire for expansion led to increased settlement in the Oregon Territory, which was jointly occupied with Britain before being acquired by the U.S. in 1846 through negotiation.
- **Mexican-American War (1846-1848)**: Resulted in the U.S. gaining a significant portion of Mexico’s northern territories, including present-day California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming, through the Treaty of Guadalupe Hidalgo.
2. **Increased Migration**: The ideology spurred waves of settlers moving westward, leading to rapid population growth and the establishment of new states.
3. **Impact on Indigenous Peoples**: The expansion had devastating consequences for Native American populations, including loss of land, culture, and lives, as settlers pushed westward, leading to forced removals (such as the Trail of Tears) and violent conflicts.
4. **Slavery and Sectional Tension**: The acquisition of new territories raised significant debates over the expansion of slavery into these areas, contributing to sectional tensions that would eventually lead to the Civil War.
In summary, Manifest Destiny shaped the territorial growth of the United States dramatically, transforming it from a collection of states along the Atlantic coast to a continental nation. It was a fundamental force that influenced American history, culture, and policy during the 19th century.
