Final answer:
The colonists' success in their revolution against Great Britain can be attributed to their unity, the signing of the Declaration of Independence, and the support they received from France.
Step-by-step explanation:
The Revolution succeeded because colonists from diverse economic and social backgrounds united in their opposition to Great Britain. A sense of community against a common enemy prevailed among Patriots, even though there were colonists who remained loyal to the crown or preferred to remain neutral. The colonists' success in their revolution against a strong country like Great Britain could be attributed to factors such as their unity, the signing of the Declaration of Independence, and the support they received from France.
