At first when Great Britain received the Declaration of Independence from the colonists, they were silent about it. The signers of the document knew that by doing so that they have validated their rebellion. The British saw the signers to be treasonous.
The Declaration of Independence was ratified on July 4th, 1776. It contained the grievances of Americans (who were under the British rule at this time) against the rule of the British King and they sought for independence.
It was the idea of "Manifest Destiny" that was the belief that it was God’s plan for the United States to own most or all of North America, since people thought the US was "destined" to occupy all the territory from the Atlantic to the Pacific.
