Answer:
From 1754, with the beginning of the French and Indian War, the population of the then British colonies in America began to acquire a feeling of national unity based on the common characteristics of the colonists, the culture of the colonies and the confrontation to a common enemy such as the French.
With the end of the war in 1763, the colonists understood that they did not need Great Britain to defend themselves from external threats, since the colonies alone had defeated the French. Then, added to this, the imposition by Parliament of a series of unfair taxes caused the colonists to rebel against Great Britain, considering themselves a different nation with its own idiosyncrasies.
This originated the beginning of the Revolutionary War, where the colonies embraced the liberal ideology to form a new nation, the United States of America.
