Although Manifest Destiny was rooted in the idea of expansionism, the racial component was also an integral part of this western movement. Because of America's growing successes in technology, agriculture, and communication, the culture became overwhelmed with a new sense of self confidence and superiority. When American leaders decided to officially move west and dominate the geographical landscape, the underlying message what that they held an inherent superiority over the native people. This sense of righteousness entails that racial component. Instead of merely being executed in beliefs of liberty and presumed prosperity, the Manifest Destiny was based in the belief that "Indian" culture was subordinate to American lifestyles.
Not only was there an ideological component to the movement, but the economic incentive to move west also carries a heavy racial bearing. The white people living in New England believed that the rich and luscious lands of the West were being wasted by the Native Americans. Simply because the Native people did not use the land for cattle herding and other American agricultural practices, they were perceived as wasteful. The white people failed to understand the intrinsic beauty and value of the land, unlike the appreciative Native Americans. By completing Manifest Destiny, the settlers of America not only declared their racism towards those with different practices, but they failed to acknowledge the benefits of cultural customs that they did not create themselves. The racial aspect to Manifest Destiny is undeniable, despite the argument that it was purely sparked from an inherent need to promote freedom and prosperity.
In Michael Hunt's book, Ideology and US Foreign Policy, he highlights how the United States used racism in it's policies and relationships to other foreign states. As the United States expanded, policy makers focused on racial and religious purtiy to justify expansion.
Domestically, we see manifest destiny affect the First Nations, pushing various indigenous tribes into reservations and forcefully ''civilizing" these individuals. Indigenous Americans living in the Midwest were taken from their tribes, forced to learn English, and assimilate into American society. Similarly, we see this happening internationally, with the United States forcing Japan's Meiji empire to open it's ports and encourage trade with American shareholders. This was supported by the belief that Americans were racially superior than the Japanese and Chinese, and needed Weatern/American influences, such as Christianity, democracy, and capitalism to be civilized throughout the globe.
With these ideologies spreading America's influence and power, indigenous and native cultures took a backseat. Because other cultures and races were seen as inferior, there is a strong racial component to manifest destiny.
There was a racial component to Manifest Destiny. The majority of Americans believed that the white Anglo-Saxon Protestant was the best possible person.
Americans in the 1830s and 1840s saw a lot of progress. The nation was growing rapidly. New innovations such as interchangeable parts were making goods cheaper. The nation was gaining new canals and railroads. The nation was also dredging rivers and improving harbors. It seemed inevitable that the new nation would continue on an upward trajectory. Many attributed this to the Protestant work ethic.
When Americans looked West, they viewed a land that was in need of good stewards—people who could make the land profitable. Throughout history, European-Americans viewed Native American culture as being lazy. They often discounted Native American agriculture as just a bunch of weeds thrown together haphazardly. The European-American thought that all farming should take place in neat rows, with fences for the livestock. Anything that did not conform to this must be wrong. These Americans looked West and thought that God intended all that land to be used according to white ways. This was the racial component to Manifest Destiny: it was about not just spreading democratic ideals but also spreading white customs.
