Question

Which is an example of the concept of Manifest Destiny in action?

Answer 1

America’s expansion into the western frontier

Answer 2

In the nineteenth century US, Manifest Destiny was a conviction that was generally held that the predetermination of American pioneers was to grow and move over the mainland to spread their conventions and their establishments, while in the meantime edifying progressively crude countries.

They felt that the Indians' absence of human progress demonstrated that they were mediocre. Beyond any doubt it is extremely helpful.
