Final answer:
White Americans benefited the most from Manifest Destiny, while Native Americans, Mexicans, and African Americans faced negative consequences.
Step-by-step explanation:
The group of people who benefited the most from Manifest Destiny were White Americans. Manifest Destiny was a belief that the United States was destined to expand from coast to coast, and it resulted in the westward expansion of the country. As a result, white Americans gained access to new lands and resources, increased political power, and economic opportunities.
On the other hand, Native Americans were greatly impacted negatively by Manifest Destiny. They faced forced removal from their ancestral lands, loss of their traditional way of life, and devastating conflicts with the expanding United States.
Mexicans also suffered due to Manifest Destiny. The Mexican-American War, which was a direct result of the expansionist mindset, led to Mexico losing a significant portion of its territory, including present-day California, Nevada, Utah, and parts of Arizona, New Mexico, Colorado, Wyoming, Kansas, and Oklahoma.
Regarding African Americans, Manifest Destiny had complicated effects. While some African Americans did migrate westward in search of new opportunities or to escape slavery, they still faced racial discrimination and the continued institution of slavery throughout much of the country.
