Question

I need help on thinking of a sentence for Manifest Destiny

Answer 1

I can suggest some sentences:
1) you can describe what it was:

Manifest Destiny was the belief that settling in America was a destiny, or right, of the settlers.

2) you can describe its effect:

Manifest Destiny was a belief that justified many injustices towards the indigenous people because it suggested that the settlers had a right for the land, which in turn undermined the indigenous claim to the land.
