Question

How did Manifest Destiny affect the growth of the nation?

Answer 1

Well, Manifest destiny meant that the US wanted to control land from the Pacific to the Atlantic, so they wanted most of North America. This meant that they displaced many Native Nations. The US could have reconsidered their motivation but at the time most people had the idea of white supremacy so they did not really care about Natives, and therefore did not reconsider their motivations.
